摘要
采用预水解的二氧化钛(TiO_2)溶胶与丙烯酸树脂共混或原位聚合的方法成功地制备了均匀透明的丙烯酸树脂/TiO_2有机—无机杂化材料。通过原子力显微镜(AFM)、X—射线光电子能谱(XPS)和表面接触角研究了杂化材料涂层的表面性质。结果发现在杂化材料中添加TiO_2后,涂层的表面粗糙度、表面Ti元素含量和表面自由能增加,接触角下降。
Acrylic resin/titania organic -- inorganic hybrid materials were successfully prepared by the in situ polymer-
ization of acrylic monomers as well as blending the synthesized thermoplastic acrylic resins with titania sols which were firstly
prehydrolyzed from the precursor of Ti(OBu^n)_4. The surface properties of the hybrid coats were characterized by atom force
microscopy (AFM). X-ray photoelectron spectroscopy (XPS) and contact angle measurement. The results showed that the
surface roughness. surface titanium content and surface free energy of the hybrid films increased and contact angle decreased
for the hybrids with titania embedded.
