| Abstract: | The starch/PVA blend was prepared by means of high speed stirring and its properties was examined. The results indicate that a suitable mechanical action of high speed stirring has a favorable effect on the mechanical properties, transparency and water proof of the Strach/PVA blend films. The biodigradability of PVA is enhanced and the stability of starch is improved, both of the properties are required when the Starch/PVA blends film is used in practice. The improved properties of starch/PVA films obtained are due to that the dispersion of starch in PVA is improved by high speed stirring and the interaction between starch and PVA is strengthened. |
