通过氧化和超声波作用制备了氧化石墨烯(GO)纳米相片层分散液,再与甲基丙烯酸(MAA)和烯丙基磺酸钠(SAS)进行自由基共聚反应制备了氧化石墨烯与甲基丙烯酸和烯丙基磺酸钠的共聚物 P (GO-MAA-SAS),各组分的质量比为 m (MAA)∶m(SAS)∶m(GO)=13∶6∶1.FT-IR 检测结果表明GO 与单体之间发生了共聚反应,AFM检测结果表明共聚物中GO 片层的厚度为4 nm、长宽在5~10 nm范围.应用结果表明用10%的 P(GO-MAA-SAS)鞣制皮革的收缩温度为84℃,GO 的鞣制作用与 GO 的纳米效应和与胶原纤维的键合作用及其二者之间的协同作用有关,研究结果 GO 纳米片层可以鞣制皮革并且GO 的分散状态是影响鞣制效果的主要因素.
The nanometer dispersion solution of graphene oxide (GO)was prepared by oxidation and ultrasoni-cation,followed carried out the free-radical copolymerization with methylacrylic acid (MAA)and sodium allyl-sulfonate (SAS)to synthesize the copolymer of GO,MAA and SAS (p(GO-MAA-SAS)).The copolymer was prepared by the weight ratios of MAA,SAS and GO of 1 3∶6∶1 .The FT-IR results indicated that the copoly-merization of GO and vinyl monomers was taken placed and GO naosheets were dispersed uniformly with thick-ness of 4 nm and size of 5-10 nm.The applied results indicated that the shrinkage temperature of the leather tanned with the 10% copolymer could reach 84 ℃,and the tanning function come from the synergistic effect of nano effects and functional groups.The research result has positive meaning to preparation of leather by green and clearning process.
