Synthesis of phenolic/vinyl acetate aergel system for thermalsupper insulator applications

The development of novel thermal insulator materials is the primary measure to reduce energy consumption andmeet the cold and hot environment of constructions and thermal equipment. Today, aerogels are used as the bestthermal insulators due to their desirable properties, such as very low density, high specific surface area, andhydrophobic materials. Aerogels are nanoporous materials synthesized from a gel in which the liquid component ofthe gel is replaced by a gas without volume loss.Therefore, aerogels synthesize with desirable properties at areasonable price has attracted the attention of researchers. In this research, preparing phenolic/vinyl acetate aerogelwith ۸۵% porosity and thermal conductivity coefficient of ۰.۰۳۴ W.m-۱K-۱ was done successfully. Due to itsproperties and working temperature in the ra nge of -۴۰ to ۹۰ ℃, this aerogel can be effective as a thermal insulationin many applications.
