【摘要】 分别采用水相法和两相法简便合成了两种4-氯代邻苯二甲酸二茂钛配合物,并用IR,1H NMR,TG,EA及SEM等手段对产物的结构和形貌进行了表征.分析了反应条件对产物粒径和形貌的影响,研究了茂钛配合物在含水复合弹性体介质中对电场作用的响应性能.结果表明,两种方法所得配合物的结构有所不同,水相法所得配合物中羧基氧以单齿形式与钛(Ⅳ)配位,而两相法中羧基氧则以双齿形式与钛(Ⅳ)配位.在不同条件下获得的两种配合物均聚集为空心微球,粒径分别为0.5～1μm和2～5μm.它们都具有较强的电场响应性能,且该性能与分子结构和微球表面润湿性相关.更多还原

【Abstract】 4-Chlorophthalate titanocene complexes were synthesized by reacting Cp2TiCl2 with 4-chlorophthalic acid in water or in CHCl3/H2O medium.The complexes were characterized by TG,IR,1H NMR,SEM and EA.The effects of reactive condition on the particle size and the morphology of complexes were investigated.In addition,the electric field response performance of titanocene complexes which were dispersed in the glycerin/gelatin aqueous elastomers were also studied.It was found that there are differences in the structure of the complexes which were synthesized by different methods.The hollow microspheres of complexes with diameter of 0.5₁ μm and 2₅ μm were obtained by aqueous phase method and two-phase method,respectively.Both of the complexes have obvious response to electric field.更多还原
