一种高负载量的分子筛 / 纸浆纤维复合材料及其制备方法和应用
By selectively oxidizing pulp fibers and hydrothermally synthesizing type A molecular sieves, the problems of low molecular sieve loading and poor uniformity on pulp fibers were solved, and a high-loading molecular sieve/pulp fiber composite material was prepared. This composite material was then applied to water-sensitive test paper, achieving a highly sensitive color response.

AI Technical Summary
In existing technologies, molecular sieves have low loading capacity and poor uniformity on pulp fibers, and the bonding stability between modified molecular sieves and fibers is weak, which limits the performance of composite materials.
By selectively oxidizing pulp fibers to convert -OH to -COOH, and then impregnating them in an aqueous solution of aluminum and alkali with a silicon source solution, a type A molecular sieve is synthesized in one step via a hydrothermal method, thus preparing a high-load molecular sieve/pulp fiber composite material.
The loading and uniformity of molecular sieves on pulp fibers were significantly improved, enhancing the stability of the composite material. Highly sensitive water-sensitive test paper was prepared through modification treatment.
