Method of producing open-cell material, the open cell material, and a method to use the open cell material

摘要

Range 5~1000kg / m ^3, an average pore diameter in the range of ² / g ^0.1~50m range 1μm~1mm, a BET surface area density, and acoustic absorption factor at a frequency of 2000Hz in a layer thickness of 50mm There is a modified open cell foam in excess of 50%, a range of 1~4000ppm, mean diameter (number average) is continuously modified with fixed particles in the range of 5nm~900nm based on the weight of the unmodified open-cell foam cell foam.
