| 摘要: |
| 以实验室合成的七苯基-单氯丙基POSS(POSS-Cl)为原子转移自由基聚合(ATRP)的引发剂,合成了含POSS的聚甲基丙烯酸三氟乙酯(PTFEMA)均聚物(POSS-PTFEMA)、POSS聚甲基丙烯酸甲酯-b-聚甲基丙烯酸三氟乙酯(POSS-PMMA-b-PTFEMA)和POSS聚甲基丙烯酸三氟乙酯-b-聚甲基丙烯酸甲酯(POSS-PTFEMA-b-PMMA)的POSS嵌段共聚物。利用傅里叶红外光谱(FT-IR)、核磁共振(NMR)等方法确定了POSS聚合物的结构,凝胶渗透色谱(GPC)表征了POSS聚合物的分子量和分子量分布。热失重(TGA)分析表明,3种POSS聚合物表现出良好的热稳定性能。对聚合物膜的疏水疏油性研究表明,聚合物膜对水接触角为97°~101°,对正十二烷的接触角则为36°~40°,且随聚合物中TFEMA聚合度的增大,表面能减小,接触角随之增大。 |

| Abstract: |
| Three tadpole-shaped POSS fluorinated acrylate polymers, POSS-poly (trifluoroethyl acrylate) (POSS-PTFEMA), POSS-poly (methyl methacrylate)-b-poly (trifluoroethyl methacrylate) (POSS-PMMA-b-PTFEMA) and POSS-poly (trifluoroethyl methacrylate)-b-poly (methyl methacrylate) (POSS-PTFEMA-b-PMMA), were synthesized via atom transfer radical polymerization (ATRP) using 3-chloropropyl-hepta (phenyl) POSS (POSS-Cl) as the initiator. The structures of the initiator and the related three hybrid polymers were characterized with fourier transform infrared (FT-IR) spectroscopy and nuclear magnetic resonance (NMR) techniques, and the molecular weights and molecular weight distributions were determined with gel permeation chromatography (GPC). Thermal stabilities of the hybrid polymers were evaluated by thermal gravimetric (TG) method, and the results indicated that the hybrid polymers exhibited excellent thermal stability. In addition, surface hydrophobic and oleophobic properties of the hybrid polymers were shown that on the polymer films the water contact angles were about 97°~101°, and the dihexyl contact angles were about 36°~40°. Furthermore, it was found that with the increasing of the degree of polymerization of TFEMA, the surface energy was decreased which leaded higher contact angles. |
