▎ 摘　　要

NOVELTY - An aminated enhanced modified straw-based composite material is prepared by slowly adding 80-90 pts. wt. aminated enhanced modified straw, 1-10 pts. wt. graphene oxide, and 1-10 pts. wt. alginate into deionized water having bath ratio of 1:10-20, ultrasonically treating, drying, crosslinking with calcium ion, and freeze-drying. USE - Preparation of aminated enhanced modified straw-based composite material (claimed). ADVANTAGE - Process is environment-friendly, product is easy to desorp and reusable and has good mechanical property, organized structure, high porosity, large absorption amount, fast absorption speed, absorption stability, heat resistance, hot water resistance, and improved uniformity and durability, and raw material is low cost and has natural substance and rich source.
