以平均粒径为0.7～0.9 μm的明胶(Gelatin)微球为基核,通过定向沉积自组装法成功制备了以Gelatin为核、BaTiO3为壳的Gelatin/BaTiO3核壳复合粒子.利用TEM、XRD、FT-IR、TG和光学接触角测量等技术对复合粒子的形貌、结构、组成及表面亲水性能进行了研究.结果表明,复合粒子为球形微粒,具有良好的表面亲水性和分散稳定性,BaTiO3壳层约占粒子总质量的18.8％,具有立方相晶相结构.将粒子分散到水凝胶弹性体中,测量在有/无电场作用下得到的弹性体的储能模量,借以考察复合粒子在弹性体中的电场响应性能,发现Gelatin/BaTiO3复合粒子的电场响应性能明显强于纯BaTiO3粒子.说明将BaTiO3包覆在聚合物上能显著提高BaTiO3粒子的电场响应性能.
