基于SEBS/纳米炭黑复合膜的电阻式应变传感材料制备及其性能研究
Preparation and Properties Study of SEBS/Nano Carbon Black Composite Membrane for Resistor-Type Strain Sensor
摘要
Abstract
A novel strain sensor was prepared usingraw materials ofthe thermoplastic elastomer of Styrene/Ethylene/Butene-Styrene(SEBS)and nanoparticles of carbon black(NCB). The sensor is in the form of a composite mem-brane that was manufactured using the melt blending and compression molding method. The mechanical properties and electro-resistance during the strain sensing of the membrane was studied. The experimental tests showed that the prepared SEBS\NCB composite membrane had excellent elastic mechanical properties,i. e. the elongation at break was 410.8%,and the tensile strength was 2.5 MPa. After 1000 times of cyclic stretching,the permanent deformation rate was controlled in 3%. The strain sensing tests showed that the resistance increased linearly with the increase of the tensile ratio of the composite membrane,and the rate of the dynamic tensile resistance was greater than the rate at static state where the resistance varied along the stretching length. The composite membrane was demonstrated in the application of human arm bending tests. The results showed that such strain sensor could record the bending numbers and bending strain precisely, then the amount of exercise could be calculated for people who wanted to know his/her exercise effect,thus such strain sensor manifested important application value in the areas of fitness and rehabilitation therapy.关键词
