Abstract

Abstract: The effectiveness of buckypaper as a strain sensor is investigated. The key contribution of this paper is the study of piezoresistive response of both buckypaper and buckypaper composites. In addition, the manufacture of buckypaper and buckypaper composites is mentioned. The specimen is subjected to a tensile loading, and the resistance of the buckypaper is obtained using a four-point probe method and examined as a function of applied strain. Experimental results of buckypaper and buckypaper composites demonstrate that there are two different linear change sensing stages in the resistance of buckypaper with applied strain, and the linear relationship is recoverable and stable for the first sensing stage (0 – 30, 000 με). From the results obtained, it is evident that buckypaper is very suitable for strain sensing. Graphical abstract: Highlights : We propose a method for fabricating buckypaper and buckypaper composites. Buckypaper has been verified to be a typical mesoporous material. Buckypaper can be used as a strain sensor.
