Have any one here worked on the effect of porosity and holes size on the mechanical properties, inclduing tear stregth of a film? I have a porous polyethylene film and I need to know what is the effect of holes size on the non-linear properties, such as tear strength, for a fixed porosuty of 40%. The filmthickness is about 10-20um. The hole size varies from 100 nm to 1 um to 10 um to 100um and higher.
Thanks,
