Problems solved by technology

However, the lack of breathability causes discomfort to users, which greatly limits their wide application in daily use.
Although human infrared radiation control has made great progress in thermal management, most personal thermal management materials focus on radiative insulation textiles, ignoring the need for heat dissipation

Abstract

The invention belongs to the field of radiation regulation and energy control and relates to a Janus infrared radiation membrane for heat preservation of a human body. The Janus infrared radiation membrane consists of a high infrared radiation rate fiber layer, a transition fiber layer and a low radiation rate nanofiber layer as units which are overlapped in sequence and mechanically tangled together. The high infrared radiation rate fiber layer has a thickness of 0.1-5mm, an aperture of 0.05-3mu m, a diameter of 0.05-15mu m and a length of 1-100mu m; the transition fiber layer has a thicknessof 0.05-2mu m, an aperture of 0.02-1mu m, a fiber diameter of 20-800nm and a length of 2-80mu m; and the low radiation rate nanofiber layer has a thickness of 0.1-10mm, an aperture of 10-200nm, a diameter of 10-500nm and a length of 1-20mu m. The invention further discloses a preparation method of the Janus infrared radiation membrane for heat preservation of the human body. The method is simpleand controllable and simple and convenient to operate, mutually opposite radiation properties are integrated into one same membrane material, the membrane has the characteristics of being simple in structure and excellent in property, and infrared radiation performance of the membrane can be controlled effectively.

Description

technical field [0001] The invention belongs to the field of radiation regulation and energy saving, and relates to a Janus infrared radiation film for human body heat preservation and a preparation method thereof. Background technique [0002] Maintaining a stable body temperature is of great significance to the normal metabolism and good immunity of the human body. The human body has precise and reliable thermoregulation mechanisms, such as sweating, shivering and blood circulation, but fluctuating weather can destroy the thermal comfort of the human body and even affect human health. For example, drastic changes in weather can easily cause an imbalance in the immune system, and people are prone to respiratory infections and even heart-related diseases. In an indoor environment, there are usually two ways to maintain the normal body temperature of the human body: air conditioning and clothing. For air conditioning, most of the energy is wasted on empty spaces and inanima...
