摘要
采用传统自由基共聚合方法合成了新型的含氟大分子单体PFMA-MA,并将其与甲基丙烯酸甲酯(MMA)、丙烯酸异丁酯(IBA)和γ-甲基丙烯酰氧基丙基三甲氧基硅烷(MPTS)进行自由基共聚合成了长氟链丙烯酸酯共聚物(ACLC)。对该聚合物的表面性能以及本体性能进行了研究。结果表明,少量的PFMA-MA便可使得到的共聚物ACLC的憎水性大幅度提高。通过X射线光电子能谱(XPS)研究大幅提高憎水性的机理,结果表明ACLC中的长氟链段具有强烈的迁移特性,氟原子富集于表面,使得材料憎水性得到提高。ACLC具有优异的附着力、硬度和低吸水率。含长氟侧链梳形丙烯酸酯共聚物有望应用在疏水、防水涂层材料等领域。
Novel fluorinated macromonomer PFMA-MA was synthesized via conventional radical copolymerization. A novel acrylate copolymer with long fluorinated chains（ACLC） was prepared by copolymerization of PFMA-MA, methyl methacrylate（MMA）, isobutyl acrylate（IBA） and ？-methacryl propyl trimethoxyl silane（MPTS）. Surface properties and bulk properties of ACLC were investigated. The results showed that just using a small amount of PFMA-MA can greatly improved the hydrophobicity. X-ray photoelectron spectroscopy（XPS） analysis was employed to investigate the mechanism of the improvement of hydrophobicity. XPS results revealed that long fluorinated chains of ACLC had strong tendency to migrate to the surface. Fluorine atoms enriched on the surface of the films. In addition, ACLC possessed low water absorption, excellent adhesion and pencil hardness. ACLC had the prominent potential application in hydrophobic coatings.
