| 摘 要： | 分别以体积比为1∶1的异丙醇/水、甲醇/水混合溶剂作为接枝溶剂,通过调节丙烯酸单体浓度得到不同接枝率和不同表面接枝链分布的接枝膜,用接枝膜诱导形成了不同形貌特征的硫化镉.研究表明,接枝率越大,硫化镉在聚乙烯接枝膜表面的分布越密集;与甲醇/水为混合接枝溶剂相比,在异丙醇/水为混合接枝溶剂的接枝膜上的硫化镉颗粒分布比较均匀.

| Abstract: | Cadmium sulfide (CdS) formation on low density polyethylene film (LDPE) grafted with acrylic acid (AAc) was attempted. Films with different degrees of grafting and grafting chain distributions were obtained by using isopropanol/water or methanol/water (volume ratio: 1:1) as grafting solvents respectively and adjusting the monomer concentrations. Different morphologies of CdS were induced on the grafted films. The results indicated that CdS par- ticles grew faster and distributed more thickly on films with higher degrees of grafting. CdS particles formed on films grafted in isopropanol/water system distributed more uniformly than in the methanol/water system. |
