Abstract

The invention discloses an infrared-thermal-radiance polymer nano-net and a manufacturing method thereof. Wearable infrared thermal radiation management equipment which is suitable for a complex curved surface of skin of the human body is provided by utilizing an infrared thermal radiation effect in the human body and high flexibility of the polymer nano-net. The reflection effect of the low radiance of a metal material on infrared thermal radiation in the human body can reach 90% at most, and passive heat preservation of the skin can be effectively achieved. In addition, the polymer nano-netof a porous structure is used as a base material, so that the prepared infrared thermal radiation equipment has the excellent performances of the high thermal radiation shielding rate, air permeability, low polymer material consumption, high flexibility and the like. The preparation method of the infrared-thermal-radiance polymer nano-net is simple and convenient, and the energy consumption of temperature regulation can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of nanomaterial preparation, and in particular relates to a polymer nanonet with low infrared heat radiation rate, a preparation method thereof and an application in the wearable field. Background technique [0002] For outdoor environments where traditional thermal management systems (air conditioning) are difficult to apply, human exposure to rapid temperature changes, especially after strenuous exercise or walking around in winter, can lead to health problems. When the outdoor temperature decreased by 1°C, the mortality rate related to cardiovascular disease (CVD) increased by 1.72%. [0003] Wearing winter gloves made of textile materials adversely reduces hand dexterity. Finger dexterity was reduced by up to 70% and hand dexterity was reduced by up to 40% in the gloved hand compared to the ungloved hand. Therefore, it is of great importance to develop a lightweight, convenient, flexible, and wearable ...
