Thermal and dynamic mechanical analysis of films prepared from treated diatomaceous earth (DE), untreated diatomaceous earth (DE), silica and epoxy have been studied. Epoxy films with different amounts of untreated and silane-treated DE were prepared. The storage modulus of the films was found to increase with the incorporation of treated and untreated DE particles in an epoxy matrix. A broad tan-delta peak was observed for the films with treated DE as compared to that of untreated DE particles. Similar mechanical properties were observed for epoxy-untreated DE and epoxy-silica films. The thermal properties of the epoxy-DE films have also been studied using differential scanning calorimetry (DSC).
