As a kind of renewable resources with abundant reserves,the research on cellulose utilization has attracted more and more attention.In this study,cotton fibers were served as precursor and carbon fibers with uniform morphology were prepared by high temperature carbonization process.In order to maintain the morphology of the carbon fiber,the measured samples were prepared by uniformly mixing the prepared carbon fiber with a wax matrix by heat-assisted impregnation and the electromagnetic properties were inve...
