主　　题：Poly(vinyl alcohol) ZIF-8 Ice-templating Porous composite C02 adsorption 

摘      要：A bulk Poly(vinyl alcohol)/ZIF-8(PVA/ZIF-8)porous composite with aligned porous structure was prepared by ice-templating method.The microstructure of PVA/ZIF-8 porous composites was characterized by scanning electron microscopy(SEM).The results showed that the composites had regular pore structure and ZIF-8 nanoparticles were evenly distributed on the skeleton of PVA.X-ray diffraction(XRD)test results showed that the crystalline structure of ZIF-8 was well preserved in the composites.The specific surface area of the composite was characterized by nitrogen adsorption/desorption test.The specific surface area of the composite was up to 1160 m^2 g^1.PVA/ZIF-8 porous composites could also support a certain weight with almost no volume shrinkage.The carbon dioxide adsorption quantity of the composite was up to 11.3 cm^3 g^1,proving that PVA/ZIF-8 porous composite has a good application prospect in the field of carbon dioxide adsorption.
