ABSTRACT: Some physicochemical properties of UHMW-PE film such
as gas permeability, tensile strength, and corrosion resistance in acid with different
immersion time, various concentrations and various solutions and rattler testing
were studied. The obtained results showed that the values of gas permeability, tensile
strength, elongation at break, and the temperature of dissociation at weight loss
5% was 546.57 cm3·m﹣2·24 h·0.1 MPa, 37.22 MPa, 368.00%, 360°C,
respectively. In different concentration acid, the surface resistance of film accumulated
to some extent with immersion time increasing, together with that the higher acid
concentration was, the lower the surface resistance of film was. Moreover, the contact
angle of films gradually increased with the acid concentration decreasing and the
increase of immersion time. After wear testing, the mass of UHMW-PE film did not
nearly change, while the contact angle became larger with the number of turning
increasing and the value was more than 90°.
