Polyvinylsilazane layer coating and its application in poly(dimethylsiloxane) microchip electrophoresis
Abstract(#br)In this paper, reactive polyvinylsilazane (PVSZ) is employed as silicate source for poly(dimethylsiloxane) (PDMS) channel surface modification. The PVSZ submicron layer is simply constructed by flushing 1\u003cce:hsp sp=\"0.25\"/\u003ewt.% PVSZ-anhydrous DMF solution into PDMS channel for 1\u003cce:hsp sp=\"0.25\"/\u003emin. After UV and thermal curing, the reactive coating is subjected to hydrolysis reaction in an alkali solution for 1\u003cce:hsp sp=\"0.25\"/\u003eh to convert the consolidated polymer surface to silicate phase.
