| Abstract: | In this paper,analysis of the corn starch-acrylic acid graft super absorbent polymer is studied by electron microscope,scan electron microscope,infrared spectroscopy and X-ray diffraction.Other properties,such as water absorption speed,water-holding capacity,performance reutilization,water-retention and reabsorption of the soil are studied.The result shows that: starch granules can not be seen in the surface of polymer,and have no effects in water absorption.The major factor to water absorption is the network structure formed through cross-linking.Then,water absorption and water-holding capacity under high temperature and pressure were both superior. |
