| Abstract: | The properties of porous films obtained by sintering a layer of polytetrafluoroethylene (PTFE) powder deposited onto a substrate were studied. The PTFE film porosity was controlled within 50–60% and the maximum pore size was 1–3 μm. The breaking stress of the films reached ～6 MPa at a 100% relative elongation. The influence of the particle size distribution function of the initial PTFE powder on the mechanical properties of sintered films is analyzed. |
