Addition of microcrystalline cellulose to an alkyd resin/titanium dioxide film: effect on dielectric properties
In this study, various composite films were prepared by varying the amounts of long-oil Alkyd Resin (AR), Titanium Dioxide (TiO2) and Microcrystalline Cellulose (MCC). The effects of each component, TiO2 and MCC, on the properties and microstructure of the dry film were determined by examining image...
