Organic composite material for personal infrared thermal management and preparation method thereof

Abstract

The invention belongs to the technical field of infrared semiconductor materials, and particularly relates to an organic composite material for personal infrared thermal management and a preparation method thereof. According to the invention, PEDOT is taken as a film forming matter and matched with corresponding assistants to prepare two function adjusting layers on the two surfaces of a target substrate respectively, the absorptivity of a near-infrared high-absorption layer at the solar thermal radiation band is improved from 50% to 90% by adding different contents of fillers and assistants, and the near-infrared high-absorption layer is taken as the outer side to absorb solar thermal energy when in use. Meanwhile, a mid-infrared high-reflection layer on the inner side of the substrate reflects heat energy emitted by the human body, and finally human body warm-keeping gain of personal heat management is achieved from two aspects. Compared with the aspect of existing personal thermal management thermal insulation performance, the invention provides an excellent new technology. Moreover, the organic composite material disclosed by the invention meets the wearing requirements of garment materials, has biological compatibility and has no toxic or side effect on a human body.

Description

technical field [0001] The invention belongs to the technical field of infrared semiconductor materials, and in particular relates to an organic composite material for personal infrared heat management and a preparation method thereof. Background technique [0002] Infrared rays are electromagnetic waves with a wavelength distribution in the range of 0.76 to 1000 μm. All objects with a temperature higher than absolute zero 0K will emit infrared rays with different intensities and wavelengths according to their own temperature. Once the infrared ray is absorbed by the object, its radiant energy will be converted into heat energy, which will increase the temperature of the object and realize the transfer of temperature. Solar heat radiation energy is mainly concentrated in the 0.4-2.5μm band, and most of the heat loss of the human body is mainly concentrated in the 8-14μm band. Under normal circumstances, the body's own body temperature regulation mechanism can maintain a cons...
