The primary purpose of this research is to create a flexible, self-sustaining gel with an optical transparency of over 70% for light in the range of 400 to 700 nanometers. Attention is focused on identifying and controlling the effect of crosslinker concentration and degree of neutralization on the polymer gel optical transparency, structural rigidity and electroactive response. Appropriate flexible and transparent electrodes suited for the present application are identified. Spectrophotometer tests indicate that there is a large gap between the spectra from crosslinker content of 175mg and 200mg (with an intensity difference of approximately 40% at 440nm).
