中文摘要：
以二甲亚砜（DMSO）为溶剂,用多巴胺（Dopamine）胺解聚（苯乙烯-alt-马来酸酐）（P（St-alt-Man））制备双亲交替共聚物P（St-alt-Ma-Dopa）.在选择性溶剂（N,N-二甲基甲酰胺（DMF）/水）中对P（St-alt-Ma-Dopa）进行溶液自组装,用紫外分光光度计（UV）、透射电镜（TEM）、荧光探针技术、zeta电位仪等技术研究了添加剂（HCl,NaOH或NaCl）对P（St-alt-Ma-Dopa）自组装行为的影响及其胶体粒子的乳化性能.结果表明,P（St-alt-Ma-Dopa）链在选择性溶剂（DMF/水）中可自组装形成球状胶体颗粒,其临界聚集水含量（CWC）明显大于P（St-alt-Man）.体系的pH值、盐浓度等对P（St-alt-Ma-Dopa）胶体粒子的性质（粒子大小、zeta电位、亲疏水性等）有较大的影响,引入多巴胺结构使交替共聚物胶体粒子的乳化性能有所提高.
英文摘要：
Using dimethylsulfoxide（DMSO） as solvent,an amphiphilic alternating copolymer P（St-alt-Ma-Dopa） was prepared by the ammonolysis of P（St-alt-Man） with dopamine.The influences of additives（HCl,NaOH,or NaCl） on the characteristics of P（St-alt-Ma-Dopa） colloid particles after the self-assembly of the copolymer in the selective solvent N,N-dimethylformamide（DMF）/H2O were studied by UV spectrophotometer,transmission electron microscopy（TEM）,zeta potential measurements,and fluorescence probe.Results show that P（St-alt-Ma-Dopa） can self-assemble into spherical particles and its critical water content（CWC） is larger than that of P（St-alt-Man）.The size,zeta potential,and hydrophilic-hydrophobic property of these colloid particles showed a series of regular changes after the addition of HCl,NaOH,or NaCl.The emulsification of P（St-alt-Ma-Dopa） colloid particles was improved because of the presence of dopamine.
