Problems solved by technology

However, under different conditions, the size and shape of different active materials have obvious differences, and the non-uniform size and non-adjustable defects of porous carrier materials seriously hinder the loading of active materials and the reaction process. It is of great significance to efficiently utilize
Most of the existing porous active material carrier materials are metal oxides, silica gel materials, carbon materials, etc., not only the preparation cost is high, the density is high, but also the pore diameter of the prepared material does not have adjustable characteristics, and the efficient utilization of active materials cannot be realized

Abstract

The invention discloses a preparation method of an aperture-adjustable cellulose and montmorillonite nano-composite carrier material. The method comprises the following steps: firstly, preparing nano cellulose suspension by an acid hydrolysis method; then, adding montmorillonite into a saturated solution of a surface active agent to obtain montmorillonite suspension; evenly mixing the nano cellulose suspension with the montmorillonite suspension, and then carrying out cyclic shearing and homogenizing to obtain cellulose / montmorillonite nano-suspension; carrying out ultrasonic dispersion, freeze drying and vacuum drying treatment on the cellulose / montmorillonite nano-suspension to obtain the aperture-adjustable cellulose and montmorillonite nano-composite carrier material. The preparation method is simple in operation, high in controllability and low in production cost; the prepared nano-composite carrier material has the aperture size of 0.1-0.5 micron and the specific surface area of 40-100m<2> / g; the material can be naturally degraded, is harmless to the environment and can be used as active material carriers with different sizes and shapes.

Description

technical field [0001] The invention relates to the field of polymer nanocomposite materials, in particular to a cellulose and montmorillonite nanocomposite carrier material with adjustable aperture and a preparation method thereof. Background technique [0002] In recent years, porous active material carrier materials have been widely used in the fields of adsorption, loading catalysis, energy storage, etc., and have broad development prospects. As a nanoporous material with great development potential, nanocellulose not only has the inherent advantages of a wide range of sources, but also has excellent properties such as multi-dimensional network structure, high specific surface area, high strength, low thermal expansion coefficient, and high elastic modulus. A substitute for non-renewable fibers such as glass fibers. Nanocellulose has made great progress in the fields of reinforced composite materials, biomedical carrier materials, and optoelectronic materials. [0003]...
