壳聚糖与丙烯酸－2－丙烯酰胺－2－甲基丙磺酸共聚物共混膜及制备方法与应用
摘要：
本发明涉及一种壳聚糖与丙烯酸－2－丙烯酰胺－2－甲基丙磺酸共聚物共混膜及制备方法，它是以壳聚糖和丙烯酸－2－丙烯酰胺－2－甲基丙磺酸共聚物和甲酸为原料，按照壳聚糖与丙烯酸－2－丙烯酰胺－2－甲基丙磺酸共聚物质量比为1∶0.1－0.7进行配料，其制备方法包括是在壳聚糖甲酸水溶液的铸膜液中加入烯酸－2－丙烯酰胺－2－甲基丙磺酸共聚物溶液，80℃下搅拌0.5－2h，过滤，静止脱泡，在玻璃板上流延，干燥成膜，再进行H2SO4水溶液中交联，真空干燥；本发明制备简单，原料丰富，价格低廉，制膜成本低。具有较低的甲醇渗透率与较高的质子传导率，可用作直接甲醇燃料电池膜。
摘要（英）：

The invention relates to a blend membrane of chitosan and acrylic acid-2-acrylamide-2-methylpropanesulfonic acid and preparation thereof, which uses chitosan, copolymer of acrylic acid-2-acrylamide-2-methylpropanesulfonic acid and formic acid to be raw material, wherein weight ratio of chitosan and copolymer of acrylic acid-2-acrylamide-2-methylpropanesulfonic acid is ranging from 1:0.1 to 0.7. The preparation includes charging copolymer solution of acrylic acid-2-acrylamide-2-methylpropanesulfonic acid into casting liquid of chitosan formic acid, stirring for 0.5-2 hours at the temperature of 80 DEG C., filtering, defoaming in static, flow casting on glass plate, drying and membrane forming, crosslinking in H2SO4 aqueous solution, vacuum drying. The invention is simple in preparation, abundant in material, low in price and cost for membrane producing. The produced membrane has relatively low permeability of methanol, relatively high conductivity of proton, and can be used as membrane for direct methanol fuel cell.
