在水溶液中制备了带有胸腺嘧啶侧基的新型两亲共聚物的胶束,即聚苯乙烯-共聚(N-丙烯酰基胸腺嘧啶)(PS-共-PAT)。透射电子显微镜和激光散射研究表明,所得球形胶束为纳米级,尺寸分布较窄。此外,亲水性和疏水性含量之比强烈影响球形胶束的流体力学半径(113-227 nm)。在PS- co曝光后-PAT胶束对三聚氰胺的作用,三聚氰胺与胸腺嘧啶之间的三氢键键识别导致聚合物胶束的聚集,因此该聚合物胶束的蓝相透明溶液变为浑浊的乳液。1 H NMR谱和ζ电位测量进一步证实了胶束的聚集和三聚氰胺与PS- co - PAT壳之间的氢键相互作用。这些结果表明,PS- co - PAT胶束可能是三聚氰胺识别的潜在新载体。
The liquid, polymer-containing coating materials of this invention comprise a polymer of a polymerizable, nitrogen-containing, hydrophilic monomer, which may give thermoresponsive properties, and which is copolymerized with a hydrophobic, polymerizable siloxy-containing monomer, in a solvent system of a volatile hydrophobic (non-polar) liquid that is non-stinging to a user. The material forms a coating or bandage in the form of a film when applied to a surface or the skin of a user.

Antimicrobial polymer coating formulations are prepared that protect biological surfaces by treating, reducing, ameliorating, preventing or inhibiting pathogenic microorganism ingress to a human or animal host, reducing the potential for infection, particularly by necrotizing fasciitis originating microorganisms, through use of a polymer coating barrier containing antimicrobial agents that facilitates sustained release of biocidal agents active against such opportunistic microorganisms. Such formulations are effective for inhibiting microbial ingress pertaining to soft tissue and skin tears, abrasions, punctures and surgical wounds, and can be used as in water environments and as a skin protectant sunscreen and insect repellent.
