Latest Patents
One of her latest patents is titled "Crosslinked polymers with tunable coefficients of thermal expansion." This invention addresses the thermal expansion mismatch between encapsulants and the objects they encapsulate. By incorporating a negative coefficient of thermal expansion (CTE) moiety into the thermoset resin or polymer backbone, her invention allows for better compatibility in thermal environments. The negative CTE moiety acts as a thermal contractile unit, which can shrink due to thermally induced conversion, making it suitable for various applications, including passive energy generation and piezoelectric applications.
Another notable patent is "Use of latent metathesis polymerization systems for additive manufacturing." This invention involves latent metathesis-active resin compositions that can be utilized in additive manufacturing processes. The method includes extruding a latent metathesis-active resin and triggering polymerization through directed irradiation or thermal stimuli. This innovation opens new avenues for direct-ink write printing and stereolithographic printing of objects.
