Study of fabrication of PMMA microspheres for applications in large scale manufacturing
Monodispersed poly(methyl methacrylate) microspheres with the size from 5μm to 13μm were prepared by using a dispersion polymerization method.Three reaction containers with volume of 250 ml; 500 mland 2000 mlwere used to study the scalability of the fabrication process.In the case of 2000-mlreaction...

| Summary: | Monodispersed poly(methyl methacrylate) microspheres with the size from 5μm to 13μm were prepared by using a dispersion polymerization method.Three reaction containers with volume of 250 ml; 500 mland 2000 mlwere used to study the scalability of the fabrication process.In the case of 2000-mlreaction container, more than 80g of microspheres were synthesized with high efficiency, which could be utilized for the fabrication of more than 100m2of anisotropic conductive film. The products were proved to have a good quality and to be ready forcarrying forwardto the silver-plating process and the fabrication of anisotropic conductive films.Other two methods including microwave-assisted polymerization and seeded polymerization were also performed to decrease the reactiontime and to increase particles size. However, the two methods still need more optimization to yield better quality of products and efficiency of process |
