【摘要】 以多巴胺甲基丙烯酰胺及N-异丙基丙烯酰胺为单体,采用自由基聚合方法制备了含有邻苯二酚单元的聚合物poly(NIPAM-co-DMA),并将该聚合物与1,4-苯二硼酸(BDBA)作用形成聚合物凝胶,考差了NaOH浓度,poly(NIPAM-co-DMA)与BDBA用量对形成凝胶的影响,研究结果表明该聚合物凝胶可实现凝胶-溶胶转变并具有自愈合性能.更多还原

【Abstract】 Catechol unit-containing polymer(poly(NIPAM-co-DMA)) is prepared by free radical polymerization method using Dopamine methacrylamide and N-isopropylacrylamide as monomers.This polymer forms polymer gel with 1,4-Phenylenediboronic Acid(BDBA),the influence of NaOH concentration and the dosage of poly(NIPAM-co-DMA the) or BDBA on forming the gel is studied.The results indicates that the polymer gel could realize gel-sol transition and exhibit self-healing properties.更多还原
