Abstract(#br)The aim of this work was to synthesize a non-isocyanate poly(dimethylsiloxane) hydroxyurethane with biomimetic terminal catechol moieties, as a candidate for inorganic and metallic surface modification. Such surface modifier is capable to strongly attach onto metallic and inorganic substrates forming layers and, in addition, providing water-repellent surfaces. The non-isocyanate route is based on carbon dioxide cycloaddition into bis-epoxide, resulting in a precursor bis(cyclic carbonate)-polydimethylsiloxane (CCPDMS), thus fully replacing isocyanate in the manufacture process.

Abstract(#br)Modern light wearable electrical devices require flexible, conductive materials for the development of portable and/or wearable devices. In this study, a flexible carbon nanotube (CNT) electrode is prepared, and the conductive CNTs are deposited on a flexible polydimethylsiloxane (PDMS) substrate using a combination of inkjet printing and transfer printing methods. Aqueous CNT ink is printed on a commercial overhead projector film.
