Paper 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 solgel precursor, and DNA-CTMA was blended in to the resulting sol-gel at various weight percentages. The blends were tested for their dielectric properties and dielectric breakdown strength; the 5% DNA blend was found to be optimal with a dielectric constant in the range of 7.5, while the breakdown strength was greater than 800 V/μm for 1 μm films and about 500 V/μm for 5μm films. Hybrid sol-gel/DNA-CTMA/barium titanate nanoparticle composites were also formulated and their dielectric properties measured. While a high dielectric constant was achieved (38), this came at the expense of a significantly reduced breakdown voltage (160V/μm). We discuss these results as well as other aspects of the dielectric and electrical properties of these blends.
