The Ultraviolet Irradiation Modification of PTFE on the Compatible Properties of Clay/EPDM Composite

Abstract

Clay and ultraviolet irradiation treated PTFE filled clay/EPDM/PTFE composites were prepared. Results show that the tensile strength increase with the irradiation time, and the tribological properties of the ultraviolet irradiation treated PTFE filled clay/EPDM/PTFE composites are superior to those of clay/EPDM/PTFE composites in terms of the crosslink between the reinforcing particle and matrix. This may be due to the nanoscale effects, and the strong interaction force existed between the matrix and the clay interface.
