High-Performance Bio-Based Cyanate Ester Resins with Low Moisture Uptake
Abstract
Key physical characteristics including density, packing fraction, moisture uptake, and as-cured dry glass transition temperature of cyanurate networks formed from bio-based cyanate esters synthesized from the natural product anethole were examined. The results showed that both equivalently high glass transition temperatures and lower moisture uptake compared to commercial materials could be achieved, though, for the non-optimal cure schedules studied, not in the same network. The most important factor in moisture uptake appeared to be the relation between the cure schedule and the glass transition temperature of the developing network. By optimizing these parameters, it may be possible to produce networks that exhibit both a higher glass transition temperature as well as lower moisture uptake compared to commercial materials.
