New silane and siloxane compounds containing cyclic carbonate functional groups were synthesized and characterized. The compounds were prepared via two routes: hydrosilation of SiH containing siloxanes and alcoholysis of chlorosilanes with hydroxy-terminated oligoethers. The products were purified by distillation and solvent extraction and characterized using 1H, 13C, and 29Si NMR. Upon doping with...
A poly(dimethylsiloxane) (PDMS)-based functional microfluidic device containing a charged matrix of PDMS pillar arrays grafted with hyperbranched polyglycerols (HPGs) was developed. Samples of PDMS were modified with allylamine plasma to form amine groups on the surface prior to the covalent grafting of succinimdyl ester-functionalized HPGs. The anionic functionality of the PDMS channel matrices was...
