▎ 摘　　要

NOVELTY - Pressure-temperature dual sensing aerogel material with a dual-channel structure is a conductive porous material formed by compounding a two-dimensional conductive nanosheet material and semi-crystalline polyethylene oxide, the microporous wall has a multi-level layered structure, and the flexible microporous wall is of a first conductive channel structure. The polyethylene oxide (4) is inserted between the two-dimensional conductive nano-sheet layers to form a multi-level layered nano-pore channel in the interior of the microporous wall, where the multi-level layered nano-pore channel is of a second conductive channel structure, when the pressure is applied, the walls of the micro-pores are bent, folded and deformed in mutual contact, so that the resistance is changed, when the temperature changes, the polyoxyethylene is converted from a semi-crystalline state and an amorphous state, and the nano pore channel shrinks or expands to generate resistance change. USE - Pressure-temperature dual sensing aerogel material with a dual-channel structure used for preparing a flexible wearable pressure-temperature sensor which can detect and identify pressure and temperature signals simultaneously (claimed). ADVANTAGE - The pressure-temperature dual sensing aerogel material with a dual-channel structure can accurately detect and identify temperature and pressure signals and pulse waveform changes of a human body under different body temperature states. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing pressure-temperature dual sensing aerogel material with a dual-channel structure, which involves mixing and stirring the two-dimensional layered transition metal nanosheet aqueous dispersion liquid and the polyoxyethylene aqueous dispersion liquid to form a stable and uniform composite dispersion liquid; the addition amount of the polyoxyethylene is 5-40 wt.% of the mass of the two-dimensional layered transition metal nanosheet material, the concentration of the two-dimensional layered transition metal nanosheet aqueous dispersion is 5-40 mg/ml, and preparing a conductive aerogel structure by freeze drying to form a multistage layered nanometer pore canal structure with polyethylene oxide inserted between two-dimensional layered transition metal nanometer sheet layers.
