甲基丙烯酰氯改性电气石功能聚合物的制备与性能表征

Preparation and characterization of functional copolymer with tourmaline modified by methacryloyl chloride

通过甲基丙烯酰氯的表面改性,在电气石表面引入带双键的有机官能团制备了可聚合的有机化改性电气石,然后与甲基丙烯酸甲酯、丙烯酸丁酯进行共聚合反应,成功地将电气石引入到了聚合物分子结构中,制备了含电气石的功能聚合物p(TMC/BA/MMA)。结果表明,表面改性没有影响电气石的功能特性,所得的改性电气石及其功能聚合物均具有优良的负离子释放和远红外辐射性能,电气石在共聚物中分散稳定性良好,且该含电气石共聚物膜具有优良的力学性能。

The polymerizable tourmaline was prepared by surface modification of tourmaline with methacryloyl chloride and then it was copolymerized with methyl methacrylate and butyl acrylate to synthesize the tourmaline-containing functional copolymer p（TMC/BA/MMA）with the tourmaline introduced into the copolymer.The experimental results showed that surface modification preserved tourmaline＇s anion-releasing properties and the modified tourmaline and its copolymer presented excellent anion-releasing and far-infrared radiation characteristics.In addition,the tourmaline dispersedhomogeneously in the copolymer and as a result,the functional copolymer p（TMC/BA/MMA）film presented strong mechanical properties.
