熔融凝胶是一类有机改性硅胶，在室温下刚性，在T1温度下流动，在T2 （T2 > T1）温度下固化，交联完成。(a)软化，(b)变硬，(c)再软化的过程可以重复多次。系统地研究了单取代烷氧基硅烷和二取代烷氧基硅烷的混合物，以确定合适的熔融凝胶组成。混合物和由此产生的熔融凝胶的特征在于它们的软化温度和固结温度。为了将这些材料用于密封微电子器件，对其物理性质进行了测量。
Melting gels are a class of organically modified silica gels that are rigid at room temperature, flow at temperature T1 and consolidate at temperature T2 (T2 > T1), when crosslinking is complete. The process of (a) softening, (b) becoming rigid and (c) re-softening can be repeated many times. Mixtures of mono-substituted alkoxysilanes and di-substituted alkoxysilanes have been studied in a systematic way to identify suitable melting gel compositions. The mixtures and the resulting melting gels have been characterized for their softening temperatures and consolidation temperatures. With an interest in using these materials for sealing microelectronics, their physical properties have been measured.
