摘要
在介绍逾渗理论的历史发展及其描述方法的基础上,总结了聚合物共混体脆韧转变(BDT)中的逾渗模型的提出、发展及应用.并指出对BDT逾渗模型的进一步研究具有很明显的科学意义和实际意义.提出了可深入着手研究的五个方向,即建立系列聚合物和系列共混体系的逾渗模型、将其宏观性能与组分特征参数建立联系、展开脆韧转变的逾渗理论的过程研究、进行纳米共混物脆韧转变的逾渗研究以及聚合物体系逾渗过程的计算机模拟.
The development and descriptive methods of percolation theory are outlined in this paper.Based on its introduction, the presentation, development and application of percolation theory in brittle-ductile transition(BDT) of polymer blends are summarized.It is pointed out that,further research of BDT percolation theory is of obviously scientific and technological significance.The five aspects of further research is put forward which are (1) establishment of percolation model applied to a series of polymers and polymer blends systems,(2) relationship of macroscopic properties and characteristic parameters of components,(3) research of the process of BDT with percolation theory,(4) research of BDT of nano-hybrids with percolation theory,and (5) application research and computer simulation of percolation model of polymer systems.
