Abstract

The invention discloses an anti-gamma-radiation composite force-sensitive structure based on carbon nanotube sponge / PDMS / WO3, which comprises a carbon nanotube sponge layer located in the middle, PDMS layers are attached to the surfaces of the two sides of the carbon nanotube sponge layer, and WO3 particles are impregnated in the PDMS layers. The three-layer composite structure is specifically as follows: a middle layer is a conductive layer formed by carbon nanotube sponge and PDMS and is used for expressing flexible force sensitive performance; an upper irradiation shielding layer and a lower irradiation shielding layer are composed of tungsten oxide and PDMS and used for shielding gamma rays. The force-sensitive structure is simple to prepare, low in cost, good in chemical stability, good in bending performance and wide in application scene. The composite structure can be attached to the surface of a to-be-detected object, changes of bending, stretching and the like of the to-be-detected object can be detected, and damage of gamma irradiation to the to-be-detected object can be prevented.

Description

Technical field [0001] The present invention relates to a composite force-sensitive material and anti-irradiation technology field, specifically a gamma radiation-resistant carbon nanotube sponge / PDMS / WO 3 Composite force-sensitive structure. Background [0002] Irradiation-resistant force-sensitive materials can not only realize real-time monitoring of object strain in the irradiated environment, but also protect electrical appliances or workers working in dangerous environments such as strong radiation. The anti-irradiation design of force-sensitive materials can expand their application scope and increase their service life in harsh environments, which has important application value, especially in aerospace, military, nuclear energy and other related industries. [0003] With the development of aerospace, medicine, nuclear reaction and other fields, flexible force-sensitive materials are inevitably exposed to high-energy irradiation such as X-rays, neutrons, and gamma ray...
