The effect of microfibrillated cellulose content and foaming temperature and time on the foaming behavior of dry poly(vinyl alcohol)(PVOH)/ microfibrillated cellulose(MFC) composites was investigated. PVOH/MFC composites were prepared by the solution film casting method and foamed via the batch depressurization foaming process with a physical blowing agent supercritical CO2. The rheological properties and thermal properties of PVOH/MFC composites were characterized. Microfibrillated cellulose fiber acted as...
