用非辐射能量转移荧光技术研究了乳胶粒成膜过程中聚合物的相互扩散。研究了甲基丙烯酸1-萘乙酯或甲基丙烯酸9-蒽酯能量转移对标记的聚甲基丙烯酸丁酯和聚甲基丙烯酸戊酯的模型乳液聚合物。测量颗粒尺寸、聚合物Tg和聚合物相容性对颗粒间扩散的速率和程度的影响。此外，在薄膜形成的最后阶段，TEM图像的时间依赖性增强了相互扩散的概念图
Polymer interdiffusion between latex particles during film formation is studied using the fluorescence technique of nonradiative energy transfer (NET). Model emulsion polymers of poly(butyl methacrylate) and poly(amyl methacrylate), labeled with the energy transfer pair of 1-naphthylethyl methacrylate or 9-anthryl methacrylate, are investigated. The effects of particle size, polymer T g , and polymer compatibility on the rate and extent of interparticle diffusion are measured. In addition, the time dependence of TEM images during the final stage of film formation augments the conceptual picture of interdiffusion
