Abstract In this work, the dielectric properties of polymethyl methacrylate (PMMA) were obviously improved by using graphene encapsulated microspheres through soap-free emulsion polymerization technique. Scanning electron microscope (SEM) observation implied that styrene-butyl acrylate copolymer (SBA) microspheres and reduced graphene oxide encapsulated SBA microspheres (rGO@SBA) was successfully obtained through using soap-free emulsion polymerization. The dielectric constant of PMMA/rGO@SBA could reach 46.64 at 1000 Hz by incorporating only 0.26 wt% rGO. On the other hand, three different PMMA based composites were also prepared by adding rGO and SBA through conventional emulsion polymerization and simple physical blending. The dielectric constant results revealed that all these composites presented low dielectric constant compared with composites through soap-free emulsion polymerization technique. The possible reason was that the isolated rGO sheets can interconnect with each other to from three-dimensional segregated network structure through hot pressing technique. SEM results demonstrated that the rGO encapsulated SBA structure could be retained after hot pressing. Therefore, soap-free emulsion polymerization technique can favorably fabricated rGO encapsulated polymer microspheres with high dielectric properties.

Binder Removal

ABSTRACTCompact samples of alumina and polymethyl methacrylate have been heated in a 2.45 GHz microwave cavity and by conventional heating in an electric furnace. Various heating schedules have been used to effect the removal of the polymeric binder by thermal decomposition. Dielectric properties, porosity and other physical properties have been investigated in order to better understand the binder removal process in a microwave field. Results of the study emphasize the amount of carbon residuals remaining in the bulk.

Polymerization Method

The soap-free emulsion of vinyl acetate (VAc)/butyl acrylate (BA) copolymer was prepared by a semi-continuous and pre-emulsification polymerization method, using ammonium sulfate allyloxy nonylphenoxy poly(ethyleneoxy) (10) ether (DNS-86) as a reactive emulsifier. The effects of DNS-86 on the stability of the emulsion and the properties of the latex film were investigated. The infrared spectrum, thermal stability, glass transition temperature and micromorphology of latex were also studied. The results showed that the emulsion had the best stability and the conversion rate reached a maximum of 98.46% when the DNS-86 amount was 4 wt % of the total amount of monomers. Compared with the PVAc latex synthesized with octylphenol polyoxyethylene ether (10) (OP-10), the latex prepared with DNS-86 has higher thermal stability and ionic stability, whereas the latex film has better water resistance.
