The result of PVA scaffolds have diameter is 6 cm and average thickness is 0.34 cm to calculating % porosity is -39.2 %. It shows that the PVA scaffolds structure is not due to preparing the PVA solution. Maybe the solution is not still in the proper temperature. It make the salt that put to make the porous in the scaffold structure dissolve. The result of the scaffolds structure is not porous. the cylindrical semple is
