Abstract

The invention relates to the field of flexible wearable heating materials, in particular to a preparation method of a radiation-heatable MXene / polymer composite material. The preparation method comprises the following steps: carrying out surface hydroxylation treatment or polarity modification treatment on a polymer material, washing with deionized water, and drying to obtain a pretreated polymer material; and uniformly spraying an MXene solution on the pretreated polymer material, and drying to obtain the radiation-heatable MXene / polymer composite material. The preparation method is simple and safe, conditions are mild, and large-scale batch preparation can be achieved; the prepared MXene / polymer composite material has three heating modes of radiation heating, electric heating and light heating, the highest temperature in the radiation heating mode can reach 45.2 DEG C, the highest temperature in the electric heating mode can reach 85.0 DEG C, the highest temperature in the light heating mode can reach 90.0 DEG C, and the method has huge application value in the field of new-generation energy-saving heating flexible heat preservation fabrics or films.

Description

technical field [0001] The invention relates to the field of flexible wearable heating materials, in particular to a preparation method of a radiation-heatable MXene / polymer composite material. Background technique [0002] Maintaining a relatively stable and appropriate body temperature is a prerequisite for the normal performance of various functions of the human body. If the human body cannot achieve thermal balance in a short period of time, it may cause dehydration, colds and other symptoms, resulting in decreased immunity. Generally, the temperature suitable for human body activities can be met by using functional clothing or adjusting the indoor temperature. For indoor temperature regulation, the use of air conditioning or heating consumes huge resources every year, and a large part of energy is wasted on heating empty buildings and inanimate objects; while in the outdoor environment, keeping the human body warm is equally important. Outdoor heating mainly relies on ...
