| Abstract: | The foaming process of polyvinyl alcohol(PVAL)foaming materials were reviewed from two aspects of chemical foaming agent and physical foaming agent.The effects of inorganic foaming agent and organic foaming agent,as well as supercritical CO2physical foaming agent on the cell size,pore size and mechanical properties of PVAL foaming materials were emphatically introduced.The different foaming agents have different characteristics,the green and environmentally friendly supercritical CO2foaming agents will be the focus of future research.In addition,the application status of PVAL foaming materials in biomedical,sewage treatment and packaging fields were introduced. |
