P(NIPAAm-co-AAPBA-co-HPM-co-TMSPM)四元共聚物的温度及葡萄糖响应行为

Temperature-and Glucose-responsive Behaviors of P(NIPAAm-co-AAPBA-co-HPM-co-TMSPM)Quaternary Copolymers

通过自由基聚合法将N-异丙基丙烯酰胺(N-isopropylacrylamide,NIPAAm)、3-丙烯酰胺基苯硼酸(3-acrylamidophenylboronic acid,AAPBA)、甲基丙烯酸羟丙酯(Hydroxypropyl methacrylate,HPM)和甲基丙烯酸(3-三甲氧基硅)丙酯(3-trimethoxysilylpropyl methacrylate,TMSPM)合成为P(NIPAAm-co-AAPBA-co-HPM-co-TMSPM)四元共聚物。采用傅里叶变换红外光谱、核磁共振氢谱和动态光散射等手段对终产物进行化学结构、分子组成和响应行为等方面的鉴定与考察。结果表明合成的共聚物由NIPAAm、AAPBA、HPM和TMSPM按照设计的反应物的物质的量比组成,为短链型聚合物,兼具温度和葡萄糖双重响应性能。

The P（NIPAAm-co-AAPBA-co-HPM-co-TMSPM）quaternary copolymers were synthesized by free radical polymerization of N-isopropylacrylamide（NIPAAm）,3-acrylamidophenylboronic acid（AAPBA）,hydroxypropyl methacrylate（HPM）and 3-trimethoxysilylpropyl methacrylate（TMSPM）.Fourier transform infrared（FTIR）spectrometry,nuclear magnetic resonance hydrogen（^1 H-NMR）spectroscopy and dynamic light scattering（DLS）technique were used to analyze and identify the chemical structure,molecular composition and responsive behaviors of the copolymers.The results indicated that the resultant copolymers with short chains,were composed of NIPAAm,AAPBA,HPM and TMSPM in the designed molar ratios of reactants,and they displayed excellent dual-response towards temperature and glucose.
