在高分子多相体系中,相间界面张力(γ_(12))是微区的重要控制因素,无论是Donatelli,Sperling等提出的IPN体系微区尺寸关系式,还是Tokita提出的共混体系中分散相粒径表达式,都含有界面张力因子。 然而,由于高分子体系中界面张力测定的诸多实际困难,当前在国内外非常多的研究工作中,广泛地采用了一些替代的办法,应用较多的有以表面张力差来代替界面张力的Antonow原则延伸及一些近似的计算方法,如Wu及Girifalco和Good提出的由表
In the polymer multi-phase system, the interfacial tension (γ_ (12)) is an important control factor in the microzone. Whether it is the domain size relationship of IPN system proposed by Donatelli and Sperling et al. Or the dispersion system proposed by Tokita Phase particle size expression, all contain interfacial tension factor. However, due to many practical difficulties in the determination of interfacial tension in polymer systems, some alternative methods have been widely adopted in many research work both at home and abroad. There are more applications of Antonow with surface tension difference instead of interfacial tension The extension of the principle and some approximate calculation methods, such as those proposed by Wu and Girifalco and Good
