The main goal of PROSUITE is to develop a framework methodology, operational methods and tools for the sustainability assessment of current and future technologies over their life cycle, applicable to different stages of maturity. The project will apply the methodology for four technology cases with close consultation of the stakeholders involved, which includes cases from biorefineries, nanotechnology, information technologies, and carbon storage and sequestration. PROSUITE will show (i) how to combine technology forecasting methods with life cycle approaches, and (ii) how to develop and possibly combine the economic, environmental and social sustainability dimensions in a standardized, comprehensive, and broadly accepted way. PROSUITE will create a solid research basis for technology characterization, including the identification of decisive technology features, basic engineering modules for estimations of material flows and energy use, and learning curves. For the economic assessment, methods for the assessment for economic and sectoral impacts of novel technologies will be developed and combined with background data for scenario-based life-cycle inventory modelling. For the environmental assessment, state-of-the-art environment indicators will be proposed together with targeted method development for the assessment of geographically explicit land and water use impacts, metal toxicity and outdoor nanoparticle exposure. For the social assessment, a set of quantitative and qualitative social indicators will be selected via participatory approaches, setting the standard for future assessments. The use of various multicriteria assessment methods will be explored to aggegrate across indicators. The methods developed will be part of a decision support system, which will be output as open source modular software.

The proposed effort will utilize lithiated POSS in synergistic combination with commercial phosphates to achieve comparable processing characteristics and superior flame retardancy, smoke and toxicity to that of Derakane 510A. The POSS-phosphate synergist package will be formulated into a Hydrex nonhalogenated vinylester resin and superior mechanical properties (interlaminar shear strength and carbon fiber adhesion) will be demonstrated. An analysis of material and manufacturing cost is presented and will be validated during the effort.


Nanoscopic metallized and nonmetallized nanoscopic silicon containing agents including polyhedral oligomeric silsesquioxane and polyhedral oligomeric silicate provide radiation absorption and in situ formation of nanoscopic glass layers on material surfaces. These property improvements are useful in space-survivable materials, microelectronic packaging, and radiation absorptive paints, coatings and molded articles.

Current energy storage devices have energy densities that are barely sufficient for low cost electric-vehicles and rely on lithium ion batteries that use flammable, unsafe, liquid electrolytes. However, in order to replace liquid electrolyes in lithium batteries for hybrid electric power train systems, solid polymer electrolytes, which have the advantages of safety and flexibility, must attain conductivities of & gt; 10-3 S/cm. To date, solid polymer electrolytes with good mechanical properties and conductivities of even 10-4 S/cm have not been achieved. Using newly developed multi-ionic POSS-based lithium salts in which the Si-O-Li are replaced with Si-O-BF3Li groups, solid polymer electrolytes with ionic conductivities & gt; 10-3 S/cm will be prepared. The electron withdrawing POSS cage and BF3 groups promote dissociation of the Li+ ions. The salts are Janus-like structures in which one end contains the ionic moieties and the other end contains hydrophobic phenyl groups. When blended with polymers such as polyethylene oxide (PEO), the hydrophobic groups cluster/crystallize and the Li+ ions are solvated by the polar ethylene oxide units. In preliminary studies, the PEO was amorphous although the solid polymer electrolyte was a hard solid until ~ 120 oC, and room temperature conductivities reached 4 x 10-4 S/cm. The solid structure was suggested to be the result of crosslinks arising from Si-O-BFs Li+ (O-CH2CH2) sites, with the PEO chains linking different phenyl clusters. In order to further improve conductivities, POSS-based lithium salts will be synthesized with varying ratios of Li/phenyl groups.

The recent development of colorless, transparent polyimides provides a break-out solution for the operational and environmental protection of thin multijunction solar cells. The incorporation of polyhedral oligomeric silsesquioxanes into the polyimide backbone renders these systems radiation hard toward proton, electron and atomic oxygen degradation. The POSS polyimides also exhibit 5x improved impact and tear resistance relative to conventional imides. The incorporation of POSS also enables the spray application of a fully imidized coating and eliminates the post-bake procedures for conventional imide coatings. BENEFIT: Terrestrial solar cell encapsulation, encapsulants for quantum dot arrays, durable computer and pda screen coatings.

Polyhedral silsesquioxanes (POSS) will be modified using chloromethylation of aromatic POSS cages. These cages will then be co-cast, using solvent, with chloromethylated polysulfones and subsequently quaternized with monofunctional and difunctional trialkylamines in order to render crosslinked films containing the cage-structures. Subsequent alkalization will form anion exchange membranes with high IEC, high conductivity but low swelling, good chemical resistance against strong acids and bases and good mechanical strength. They will be used as AEMs in direct sodium borohydride/hydrogen peroxide fuel cells.

A method of using metallized and nonmetallized nanostructured chemicals as surface and volume modification agents within polymers and on the surfaces of nano and macroscopic particulates and fillers. Because of their 0.5 nm-3.0 nm size, nanostructured chemicals can be utilized to greatly increase surface area, improve compatibility, and promote lubricity between surfaces at a length scale not previously attainable.

ABSTRACT:Specialty elastomers, such as hydrogenated acrylonitrile-butadiene rubber (HNBR) and fluoroelastomer (FKM), are widely utilized as high performance seals in numerous aerospace vehicles and components. The elastomer sealing industry and its products are primarily based on a limited pool of feedstocks that were last advanced in the 1970's. Using current technology, elastomeric seals must be utilized within narrow ranges of operating conditions (temperature, pressure, chemical exposure). This increases risk for equipment failures due to unforeseen variations in operating conditions and may result in loss of equipment, facilities, mission and life. A more robust sealing approach is needed to increase safety and performance margins and to fill performance gaps in elastomeric sealing technology.BENEFIT:A leapfrog advancement in elastomeric sealing technology can be realized and productized within 30 months though the proposed transition team effort. Hybrid Plastics is an expert in manufacture of POSS chemicals and Parker is an expert in design and manufacture of elastomeric sealing technology products and distribution.

The use of nanostructured chemicals based on polyhedral oligomeric silsesquioxanes (POSS) and polyhedral oligomeric silicates (POS) are used to control porosity in organic and inorganic media. The precisely defined nanoscopic dimensions of this class of chemicals enables porosity to be both created (increased) or reduced (decreased) as desired. The thermal and chemical stability of the POSS/POS nanostructures and the ability of these nano-building blocks to be selectively placed or rationally assembled with both inorganic and organic material mediums allow tailoring of porosity.
