Nanocomposites are promising for many sectors, as they can make polymers stronger, less water and gas permeable, tune surface properties, add functionalities such as antimicrobial effects. In spite of intensive research activities, significant efforts are still needed to deploy the full potential of nanotechnology in the industry. The main challenge is still obtaining a proper nanostructuring of the nanoparticles, especially when transferring it to industrial scale, further improvements are clearly needed in terms of processing and control. The OptiNanoPro project will develop different approaches for the introduction of nanotechnology into packaging, automotive and photovoltaic materials production lines. In particular, the project will focus on the development and industrial integration of tailored online dispersion and monitoring systems to ensure a constant quality of delivered materials. In terms of improved functionalities, nanotechnology can provide packaging with improved barrier properties as well as repellent properties resulting in easy-to-empty features that will on the one hand reduce wastes at consumer level and, on the other hand, improve their acceptability by recyclers. Likewise, solar panels can be self-cleaning to increase their effectiveness and extend the period between their maintenance and their lifetime by filtering UV light leading to material weathering. In the automotive sector, lightweight parts can be obtained for greater fuel efficiency. To this end, a group of end-user industries from Europe covering the supply and value chain of the 3 target sectors and using a range of converting processes such as coating and lamination, compounding, injection/co-injection and electrospray nanodeposition, supported by selected RTDs and number of technological SMEs, will work together on integrating new nanotechnologies in existing production lines, while also taking into account nanosafety, environmental, productivity and cost-effectiveness issues.

Organic solar cells (OSC) feature several advantages over classical silicon solar cells: low cost, energy effective production, low weight and semi-transparency. This makes them apt for novel applications like, building-integrated photovoltaics (BIPV) with high market potential. However, both the efficiency and the long-term stability must be enhanced for OSCs to become profitable. POCAONTAS will develop highly efficient and stable OSCs based on tailored blends of polymers (P) with single wall carbon nanotubes (SWNT), that are ideally suited for OSCs due to their inherent stability, high carrier mobility and the tunability of optical gaps. Up to now, no breakthrough in SWNT based OSC has been achieved due to challenges with the control of SWNT-chirality, -aggregation, orbital energy mismatch and nanoscale sample morphology. Our consortium will address these issues: We will synthesize functional polymers that (i) allow for a tailored selection of SWNT chiralities, and (ii) match the SWNT energy levels to polymers for maximization of efficiency. The introduction of SWNT-P exchange protocols enables us to optimize (i) and (ii) with different polymers, avoiding compromises in performance. We will obtain optimized donor-acceptor blends, in which the SWNTs are light antenna and charge transporter. We unify leading European groups in time- (down to 10 fs) and spatially (down to 10 nm) resolved spectroscopies providing unique insights into SWNT-P interactions at the molecular level. Experts in multi-scale quantum chemical modeling will develop greater predictive power of charge transport. FLEXINK, a startup in optoelectronics materials, will provide tailored polymers. KONARKA, world leader in commercial OSCs, will build and test solar cells using our blends. Both full partners can directly exploit the projects outcome to strengthen their market position. Three associated industrial partners provide industry internships for each ESR maximizing their career perspectives.

The Earth receives the energy in 1 hour required for all human needs in a year. Harvesting solar energy will reduce harmful CO2 emissions and resolve the forthcoming energy deficit that other sources alone cannot make up. The market for stable, cheap, roll-to-roll mass-produced organic solar cells (OSCs) is estimated at 1 billion Euros by 2016. The ITN ESTABLIS will produce a team of 11 ESRs and 4 ERs to harness this pivotal point in Europes development based on a reliable, economically powerful and clean resource. ESTABLIS will be an interdisciplinary and inter-sectorial research and training network. ESRs and ERs that result from ESTABLIS will excel. They will possess a broad skill-set across a range of disciplines that are of absolute necessity to develop the industrial and academic infra-structure in OSCs. Researchers will receive training in the primary areas of synthetic organic chemistry through complementary aspects of polymer science to complete industrial scale photovoltaic device manufacture. To improve the roll-to-roll engineering and stability of opto-electronically active thin-films will require new polymers, surface treatments, rheological appraisals of polymer processing, and ageing studies. A parallel approach will develop the necessary improvements in electronic and opto-electronic properties by clarifying correlations between charge transfer, photochemistry and stability. This project will be run by meticulously interacting groups to increase the stability of strong, flexible, low-cost OSCs to 10 years so that they can be sold on a mass-market basis. ESTABLIS is an exceptionally complementary consortium of field-leading University groups and the worlds chief Industrial companies, namely, the worlds foremost producers of OSCs, Konarka, of conducting polymers, Heraeus, and of semiconducting polymers, Merck. These key European companies are at the heart to ensure that training and technological developments will be industrially operable.

Windows are critical elements to control the energy performance of buildings especially for zero-energy buildings. It is of paramount importance to develop windows which show reduced U-value, weight and costs and certain features to control and harvest energy. Such a window will have a high impact in the window industry and will reduce green house gas emissions as long as the window is affordable, can be used in renovation and in every climate zone. Therefore MEM4WIN is aiming at the following goals (1) weight reduction (2) energy control and harvesting (3) replacement of cost intensive processes and materials. (1) We will introduce a novel IG-Unit for quadruple glazing containing ultra thin glass membranes dedicated as frameless openable windows for direct application in facades. Due to this approach U-values of 0.3 W/mK can be achieved reducing weight by more than 50% and costs by 20%. (2) We will implement printed organic photovoltaics (OPVs) and solar thermal collectors for energy harvesting and micro mirrors for energy control and advances day lighting. (3) Fabrication costs will further be reduced by replacing conventional and cost intensive materials used for contacts like ITO and silver by graphene. We will introduce production methods like roll-to-plate and ink-jet printing to fabricate contacts for OPVs. At the end of the project the different components like micro mirrors, OPVs, organic light emitting diodes (OLEDs) and solar thermal collector will be integrated into a demonstrator showing the suitability of the used equipment, processes and new materials developed within MEM4WIN. Each aspect of MEM4WIN - (1) weight reduction, (2) energy control and harvesting, (3) replacement of cost intensive processes and materials - is represented by experts in this field resulting in a multidisciplinary highly motivated consortium containing participants from basic research as well as industrial endusers from whole Europe.
