Abstract:Energy
consumption in the field of heat preservation increases
every year, so it is important to develop foam with a good thermal
insulation properties. In this work, a method for the fabrication
of poly(vinyl alcohol)-polycaprolactone (PVA–PCL) blend foams
with high expansion ratio and low thermal conductivity using PVA–PCL
mixture solution via supercritical carbon dioxide (scCO2) foaming was proposed. A high water content in the mixture solution
was used as the coblowing agent, and the differences in foaming… Show more
