Surface Modification of the UHMW-PE Film Processing by Hot Compression Molding
The properties of UHMW-PE film produced by hot compression molding and films modified by acid and anti-static agent were characterized. The results showed that: a) the thickness distributing of the film which processing by calendar rolling with conventional design roller is inhomogeneity; the tensile strength was 37.22 MPa, the elongation at break was 368.00%; the transmittance increases with wavelength redshift shows short-wave absorption and long-wave transmission; initial temperature of dissociation is 320°C; the surface resistance 1010 Ω and maximum is higher than 1016 Ω. b) Acid modification the surface of UHMW-PE film moderates the surface antistatic performance. C) After modified the film with external anti-static agent, the surface resistance was around 107Ω, but anti-static properties loss rapidly after friction. If modified the film with internal anti-static agent, the surface resistance was around 1010 Ω and have a long-lasting anti-static effect.
