Abstract

The invention relates to a multi-functional composite membrane. The multi-functional composite membrane comprises the following components in parts by weight: 0.1-15 parts of conjugated polymer nano material and 85-99.9 parts of plastic, wherein the conjugated polymer nano material is selected from at least one of the following materials: poly(3,4-ethylenedioxythiophene), polythiophene, polypyrrole, polyaniline, poly(p-phenyl vinyl) and poly(dopamine melanin). The multi-functional composite membrane has high photo-thermal conversion efficiency and can be used for converting near infrared ray and infrared ray in sunlight into heat, and temperature at the periphery of the membrane and in coverage area of the membrane can be increased; meanwhile, bacteria, mould and the like are killed by heat produced by the multi-functional composite membrane; and the multi-functional composite membrane is obtained by mixing and stirring non heavy metal type and non-toxic conjugated polymer nano material with plastic and then forming a thin film by adopting an extrusion method, a calendaring method or a blowing moulding method and can be widely applied to membranes for everyday devices, membranes for packaging, agricultural films and industrial films.

Description

technical field [0001] The invention belongs to the field of multifunctional thin films, and in particular relates to a multifunctional composite film with high photothermal conversion efficiency and its preparation method and application. Background technique [0002] The plastic film industry is in a stage of vigorous development, and the demand for plastic film in China will grow at a rate of more than 9% per year. Moreover, with the continuous emergence of new materials, new equipment and new processes, plastic films will be developed in the direction of variety diversification and multi-function. However, there are few films with low cost, antibacterial, antifungal, light absorption and heat generation applied to many fields. Therefore, it is of great practical significance to develop a multifunctional composite film with high light-to-heat conversion efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a multifunctional ...
