  1. The urea - formaldehyde ( uf ) polymer / sio2 composite microspheres were prepared by polymerization - induced colloid aggregation ( pica ) method. the formation mechanism of composite microspheres is attributed to the fact that that urea and formaldehyde firstly undergo acid - catalyzed polymerization to form oligomers, and then the sol particles are adsorbed on the chain of oligomers by wan der walls force and hydrogen bonding. when the oligomers reach the critical chain length, they separate from solution due to phase separation

    對復微球形成機理的研究表明,尿素和在酸性條件下自身可以形成高分子微球,在sio _ 2酸性溶膠中發生和反應時,隨著反應的進行,齊不斷生成, sio _ 2膠體顆粒逐漸吸附在齊分子鏈上,當鏈達到沉澱臨界鏈長時,由於相分離作用,從前驅溶液中析出,同時sio _ 2膠體顆粒均勻的分佈在網路中,隨之沉澱出來,形成sio _ 2復微球。
