| Abstract Scope |
Melting gels are a class of hybrid organic-inorganic, silica-based gels which are solid below their glass transition temperatures, near room temperature, but show thermoplastic behavior when heated. While this phase change can be repeated multiple times, heating the gel past its consolidation temperature initiates an irreversible reaction that produces highly crosslinked organic-inorganic glasses. This thermoplastic-to-thermoset ability makes melting gels uniquely compatible with processing techniques inaccessible to other gels. However, melting gel consolidation reactions are highly dependent on charge interactions. Here we use electrospray deposition (ESD) of melting gels with different modifiers to reduce and enhance charge removal by mass transport to see how the charge affects film morphology, consolidation chemistry, and surface properties. Microscopy, film thickness measurements, water contact angle, and Fourier transform infrared spectroscopy were used to characterize the sprayed melting gel composites. |
