Functional polyolefins (i.e., polyethene or polypropene bearing functional groups) are highly desired materials, due to their beneficial surface properties. Many different pathways exist for the synthesis of these materials, each with its own advantages and drawbacks. This review focuses on those synthetic pathways that build up a polymer chain from ethene/propene and functionalised polar vinyl monomers. Despite many recent advances in the various fields of olefin polymerisation, it still remains a challenge to synthesise high molecular-weight copolymers with tuneable amounts of functional groups, preferably with consecutive insertions of polar monomers occurring in a stereoselective way. To overcome some of these challenges, polymerisation of alternative functionalised monomers is explored as well. © 2013 The Royal Society of Chemistry.

This project aims at the development of multiscale simulation methodology and software for predicting the morphology (spatial distribution and state of aggregation of nanoparticles), thermal (glass temperature), mechanical (viscoelastic storage and loss moduli, plasticity, fracture toughness and compression strength), electrical and optical properties of soft and hard polymer matrix nanocomposites from the atomic-level characteristics of their constituent nanoparticles and macromolecules and from the processing conditions used in their preparation. The hierarchical simulation methodology and software to be developed will be validated against two main categories of systems: silica-filled natural and synthetic rubbers and carbon nanotube filled thermoset resins. The novel ground-breaking modelling methodology should significantly improve the reliable design and processability of nanocomposites contributing to the EU Grand Challenges for reduction of CO2 emission, energy savings by light-weight high-strength nanocomposites, mobility and improved living environment. The successful outcome of the project will constitute an important advance in the state of the art and will have immediate industrial, economic and environmental impact. The multiscale simulation methodology of EU-COMPNANOCOMP focuses on soft nanocomposites (thermoplastics) whereas the complementary RU-COMPNANOCOMP focuses on glassy nanocomposites (thermosets)(grey in proposal). RU-COMPNANOCOMP is completed with EU partners for experimental validation of the multiscale modelling codes. Both EU and RU consortia work on the development of algorithms to be integrated in a multiscale modelling software package for further commercialization. A total of 213.5 man months completed with 26 man months from own resources is proposed with a project duration of 36 months appropriate for achieving the challenging objectives. EU-COMPNANOCOMP has a total cost of 2.3 million with EC funding of 1.5 million requested.

Overall objective of the SHINE project is to develop a novel generation of elastomers that undergo spontaneous self-healing, leading to enhanced durability and reliability of the products made thereof (dynamic seals, shock absorbers, anti-vibration devices for vehicles, roads, railroads and bridges). The elastomers can heal without human intervention and can undergo multiple healing stages. They can prevent damage propagation by healing the microcracks or repair themselves in the case of accidental break. The objectives include also developing and standardizing test methods to quantify the efficiency and effectiveness of the self-healing process. The scientific and technical concept is based on the use of dynamic crosslinks both covalent and supramolecular (H-bonds and ionic interactions) that can be broken and reversibly reestablished to provide self-healing. Supported by the SHINE Exploitation Plan the new elastomers will be used to formulate, compound, manufacture and evaluate the final products as listed above. The results will be disseminated to initiate further research in this field. The products made by the self-healing elastomers will have prolonged lifetime, will increase reliability and enhance safety when used in vehicles, machinery and transportation infrastructure. The societal benefits are in reduction of roads incidents, injuries and fatalities, reduction in environmental pollution, and reduction of urban noise. The economic benefits include less road maintenance work, less traffic jams and waste of time associated with this, savings in energy and natural resources consumption, reduced machinery idle time due to frequent reparations, and reduced transportation costs, which will eventually improve the competitiveness of the European industry. A total of 574 person-months with project duration of 42 months are proposed for achieving the objectives of the project. SHINE has a budget of 6,2 million , with a requested EC funding of 3,9 million .

Poly(2-oxazoline)s (POxs) are a versatile class of biocompatible polymers, which have been investigated as poly(ethylene glycol) (PEG) alternatives. In recent years, POxs have drawn significant attention as coatings for antifouling applications. In this tutorial review different approaches to immobilize POxs on surfaces as well as properties and applications of POx coated surfaces will be presented. © 2013 The Royal Society of Chemistry.

Marine biofouling, the unwanted colonization of marine organisms on surfaces immersed in seawater has a huge economic and environmental impact in terms of maintenance requirements for marine structures, increased vessel fuel consumption, operating costs, greenhouse gas emissions and spread of non-indigenous species. The SEAFRONT project will aim to significantly advance the control of biofouling and reduce hydrodynamic drag by integrating multiple technology concepts such as surface structure, surface chemistry and bio-active/bio-based fouling control methodologies into one environmentally benign and drag-reducing solution for mobile and stationary maritime applications. In parallel, a combination of laboratory-based performance benchmarking and end-user field trials will be undertaken in order to develop an enhanced fundamental/mechanistic understanding of the coating-biofouling interaction, the impact of this on hydrodynamic drag and to inform technology development and down-selection of promising fouling control solutions. This project aims to facilitate a leap forward in reducing greenhouse gas emissions from marine transport and the conservation of the marine ecosystem by adopting a multidisciplinary and synergistic approach to fouling control.
