微孔塑料气泡成核的聚合物刷子模型
Simulation of Polymer Brushes for Nucleation of Microcellular Plastics
摘要
Abstract
Nucleation is one of the key stages during producing microcellular plastics, the radius of critical nucleus is the main factors for deciding the radius of bubbles of product, nu-cleus density also decides the bubble density. The nucleation theories existing are based on classicnucleation theory mostly, classicnucleation theory has given the calculation formulae of critical nucleus and nucleus density, but it does not consider the physical speciality of pol-ymer and can't calculate the certain numerical value, so it is restricted in application. This paper will construct the nodel of brushes for nucleation of microcellular plastics from the model of polymer brushes, giving the calculation formulae of critical nucleus radius, and ana-lyxing the influence of temperature, pressure and polymer molecular weight on critical nucle-us radius.关键词
