23 Jul Bacterial cellulose / rod-like clay composite membrane and preparation method thereof
Abstract
The invention discloses a bacterial cellulose / rod-like clay composite membrane and a preparation method thereof. The composite membrane is prepared by mixing of bacterial cellulose / rod-like clay, and the rod-like clay in the composite membrane is uniformly dispersed in a bacterial cellulose nano fiber matrix. The rod-like clay and the bacterial cellulose are mixed, the rod-like clay plays the role of a strengthening material for mechanical properties of the cellulose membrane in the composite membrane and an adsorption modifying material, and by controlling of the mass ratio of bacterial cellulose powder to rod-like clay powder to 10-100:1, the thickness and mechanical strengthen and other properties of the composite membrane are control. The method is simple, the prepared composite membrane has the advantages of three-dimensional nano network structure, uniform fiber diameter and good biocompatibility, can be used as an adsorbent material for adsorption of pollutants, harmful gases, oil and other impurities, and has a potential application prospect in tissue engineering, biological sensor coating materials, cosmetics, skin care products and medical dressings and other fields.
