Secondly, PU pre-polymer was modified by acrylate monomers using twomethods.The first,PU emulsion with no saturated duplet bond was prepared.

第一種方法是先制備出含有不飽和雙鍵的PU乳液，加入丙烯酸酯單體與PU乳液共聚99视屏在线，形成互穿網(wǎng)絡(luò)欧美最新视频。

The styrene-acrylate spheres were coated with the TiO2 colloidal particles via electrostatic effect and hydrogen bond interactions with the increase of aging time, thus the film-forming capability of the solution was changed. The poor film-forming capability results in the formation of the porous structure with dense, homogeneous island morphology. Then the TiO2 porous films with dense pores can be obtained after two coating-dissolving cycles.
