合成了一系列基于倍半硅氧烷(POSS)的多面体低聚倍半硅氧烷(POSS-MMA-(HFPO)(3)MA)杂化三元共聚物P(POSS-MMA-(HFPO)(3)MA)，并用核磁共振、红外光谱、凝胶渗透色谱、差示扫描量热法和热重分析对其进行了表征。POSS笼的引入改善了这些三元共聚物的热性能。经该三元共聚物整理后的棉织物具有良好的拒水拒油性能。当POSS含量从6.4wt%增加到13.4wt%时，水和色拉油的接触角分别从接近140度增加到152度，从接近127度增加到144度。与P(MMA-(HFPO)(3)MA)共聚物涂层棉织物相比，POSS基三元共聚涂层棉织物具有更好的拒油性能，且随着POSS含量的增加有先增大后减小的趋势。POSS含量为9.5wt%的三元共聚物涂层棉织物的正十六烷(表面张力：27.4mN/m，20℃)接触角接近117度。(C)2010爱思唯尔有限公司。保留所有权利。
A series of polyhedral oligomeric silsesquioxane (POSS) based hybrid terpolymers P(POSS-MMA-(HFPO)(3)MA) were synthesized and characterized by NMR, FT-IR, GPC, DSC and TG. The thermal properties of these terpolymers were improved by the introduction of POSS cage. The cotton fabrics coated with these terpolymers possessed excellent water and oil repellency. The water and salad oil contact angle could be achieved from similar to 140 degrees to 152 degrees and from similar to 127 degrees to 144 degrees respectively as the content of POSS in the terpolymer increased from 6.4 wt% to 13.4 wt%. Compared with P(MMA-(HFPO)(3)MA) copolymer-coated cotton fabrics, POSS-based terpolymer coated cotton fabrics showed better oil repellency with a tendency of first increasing and then decreasing with an increase of the POSS content. The n-hexadecane (surface tension: 27.4 mN/m, 20 degrees C) contact angle reached similar to 117 degrees for coated cotton fabrics with terpolymer containing 9.5 wt% of POSS. (C) 2010 Elsevier Ltd.
