The microchannel of PDMS/glass chip was coated with a layer of poly-(allylamine hydrochloride)(PAH) then with poly(arylic acid)(PAA).
首次将聚丙烯氯化铵和聚丙烯酸通过静电吸附作用层层组装于聚二甲基硅氧烷/玻璃芯片内部,修饰后的芯片电渗流(EOF)随pH值的变化较小,具有较好的重复性和稳定性,EOF在2周内的变化率为1。
The blend membranes of chloromethylated/quaternized polysulfone and polyvinylidene for ultrafiltration of cathodic electrophoretic paints were prepared.
