Abstract

We investigate the dielectric and electrical properties of sol-gel/DNA-CTMA blends, with particular interest in capacitor applications in energy storage. Methacryloyloxypropyltrimethoxysilane (MAPTMS) was the sol-gel precursor, and DNA-CTMA was blended in to the resulting sol-gel at 5 weight%. The blend was then tested for its dielectric properties and dielectric breakdown strength; at frequencies below 10kHz the blend was found to have a dielectric constant in the range of 7.5, while the breakdown strength was greater than 800 V/μm, an exceptional value. We discuss these results as well as other aspects of the dielectric and electrical properties of these blends.
