探究阳离子胍盐类抗菌剂与阴离子聚电解质(羧甲基纤维素钠)的自组装过程和影响因素,对聚电解质复合物的自组装过程进行了表征,并研究聚电解质复合物在纸浆纤维上的吸附过程。结果表明:胍盐类抗菌剂与羧甲基纤维素钠混合时,可以通过静电相互作用而形成具有纳微米尺寸微球结构的聚电解质复合物;同时,聚电解质复合物LBL膜表面形貌中的复合物粒子随自组装过程进行而有所不同,LBL膜表面粗糙度随着膜层数的增加变化趋势与羧甲基纤维素钠的分子量有关;当向纸浆纤维中加入聚电解质复合物时,胍盐类抗菌剂在纤维上的吸附量远高于只加入胍盐类抗菌剂时的吸附量。
The self-assembly process and influencing factors of cationic guanidinium antibacterial agent and anionic polyelectrolyte (sodium carboxymethylcellulose) were investigated. The self-assembly process of polyelectrolyte complex was characterized and the effects of polyelectrolyte complex on pulp fiber The adsorption process. The results show that when the guanidinium salt antibacterial agent is mixed with sodium carboxymethylcellulose, the polyelectrolyte complex with nano-sized microspheres can be formed by electrostatic interaction. Meanwhile, the surface morphology of polyelectrolyte complex LBL membrane Of the composite particles vary with the self-assembly process, LBL film surface roughness with increasing the number of layers changes with the molecular weight of sodium carboxymethyl cellulose; when added to the pulp fiber polyelectrolyte complex The adsorption amount of guanidinium antibacterial agent on the fiber is much higher than that of the guanidine salt antibacterial agent.
