News from March 30th, Professor Yu Shuhong of the School of Chemistry and Materials Science, University of Science and Technology of China, using chitosan as a three-Microsoft template, developed a new synthetic strategy for the copolymerization of phenolic resin with SiO2 and phase separation at the nanoscale, and successfully developed A PFR / SiO2 composite aerogel material with a dual network structure was developed. Related results have been published on Angew. Chem. Int. Ed.
According to reports, the aerogel has a good thermal insulation effect, with a minimum thermal conductivity of 24 mW / mK, which is superior to traditional foamed polystyrene and other materials. Its heat is relatively low in a low temperature and low humidity environment The conductivity is maintained at 28 mW / mK. This material can avoid the failure of the load-bearing structure of the building in the event of a fire and gain time for evacuation.
