Study On ISBS Having Effect On The Preparation Of PMMA/Expanded Graphite/P(MMA-St) Composite Materials

Our study applied voltage 4kv, control the temperature from 85 to 90 degrees, react more than 6 hours, and then put the emulsion in the oven for drying. Finally we get poly (methyl methacrylate-styrene) nanorods.Nano-materials was added to other materials to form nanocompos-ites, but one of the important factors improving the performance of composite material is the additives dispersed in the matter uniformly or not. Nanomaterials was added to the composite material can be viewed as a disorder uncontrolled, and irregular process. This experiment was innovatively made to study on respectively blending the expanded graphite and poly methyl methacrylate-styrene nanorods with poly methyl methacrylate (PMMA) using or nonusing the method of in situ bubble stretching (ISBS), the SEM and XRD shows that after using the ISBS method, the length of expanded graphite is the original's 1/7.5, equably dispersed in the matrix. Poly(methyl methacrylate-styrene) in the matrix are almost invisible. In this study, we also test the standard spline's mechanical properties. Datas show that adding the expanded graphite by using ISBS can improve material's impact strength by 214%, and materil's haze was 121.3%. Adding the poly (methylmethacrylate-styrene) nanorod by using ISBS can improve material's impact strength by 9.3%, and material's haze was 23.9%, the transmittance descend 2.34%.
