Abstract:Carbon nanotube (CNT) foam and aerogels hold promise in the area of strain sensors because of their resistive-elastic behavior under compressive strain. To date one of the largest obstacles in the area of CNT foam and aerogels has been the lack of control over the porosity and microstructure. Using a novel hybrid foam fabrication method, we are able to create a hybrid CNT-graphene foam with engineered micro-scale pores. By varying the parameters of the pores and ratio of materials, we were able to control the size and shape of the pores, as well as the porosity and rigidity of the foam. These factors can be altered in order to fabricate samples with a wide range of resistive behavior. The goal of the study was to show suitability of our material as a strain sensor for practical purposes.
