Studies from University of California in the Area of Polymer Research PublishedPolymer ResearchNewsRx.com
By a News Reporter-Staff News Editor at Journal of Technology -- Investigators publish new report on Polymer Research. According to news reporting originating from Los Angeles, California, by VerticalNews correspondents, research stated, "Novel polyphenylene oxide (PPO) microcapsules filled with epoxy resins (PPOMCs) were synthesized by in situ polymerization technology with 2, 6-dimethy phenol as shell materials and diglycidyl ether of bisphenol A epoxy resins as core materials. The structures and morphologies of PPOMCs were characterized using Fourier-transform infrared spectroscopy, micro-confocal Raman microscope, laser scanning confocal microscopy, scanning electron microscopy and optical microscopy, respectively."
Our news editors obtained a quote from the research from the University of California, "The thermal properties of PPOMCs were investigated using differential scanning calorimetry and thermogravimetric analysis. The influences of different processing parameters such as the weight ratio of shell material to core material, kind of surfactant and reaction temperature on the morphologies and sizes of PPOMCs were investigated. Preliminary investigation on application of PPOMCs to thermosetting resins 4,4'-bismaleimidodiphenylmethane/O,O'-diallylbisphenol A (BMI/BA) system was conducted. PPOMCs can be synthesized successfully. The sizes and surface morphologies of PPOMCs may be significantly affected by different processing parameters. PPOMCs can be well prepared at about 30 degrees C, and they depend strongly on the kind of surfactant and the weight ratio of shell material to core material. PPOMCs basically exhibit high thermal stability when the temperature is below 258 degrees C. The addition of PPOMCs can improve the mechanical properties and maintain the thermal properties of BMI/BA system."
According to the news editors, the research concluded: "The released core materials from PPOMCs may repair the matrix cracks through the polymerization of epoxy resins initiated by curing agent."
