pH-responsive self assemblies for “smart surface coatings”

Baquey G., Sakai K., Perrier S., Biggs S., Chamelic Ltd, UK

Over the last few years, adsorption of polyelectrolytes at solid/liquid interfaces has gained in popularity due to their potential applications for drug delivery, for the preparation of nanosized materials and for the fabrication of smart [...]

Polymer-Controlled Growth of CdSe Nanoparticles into Micro- and Nanowires

Fahmi A.W., Oertel U., Steinert V., Moriarty P., Stamm M., University of Nottingham, UK

This work reports an easy and effective method to prepare CdSe semiconductors nanoparticles stabilised by using amphiphile diblock copolymer polystyrene-block-polyvinylpyridine [PS-b-P4VP] in nonaqueous medium. spin coating on native oxide Si-wafers showed a core-shell structure of [...]

Polymeric Nanocomposites Enabled by Controlled Architecture Materials

Shefelbine T.A., Marx R.E., Nelson J.M., Longabach J.W., Brostrom M.L., Bucket M.I., 3M Corporate Research, US

This presentation will focus on the use of Controlled Architecture Materials (CAMs): block copolymers, telechelic, gradient and star branched polymers as additives to induce the exfoliation of nanoclays in thermoplastic resins. Conventional exfoliation methods include [...]
