Surface Modification of the UHMW-PMMA Film Processing by Solvent Molding

Abstract

Abstract-This paper have compared the properties of UHMW-PMMA film with GMW-PMMA film in terms of contact angle, gas permeability, heat resistance, surface resistance changes by surface modification of UHMW-PMMA film like thermal treatment, acidation and alkalization modification. All the datas showed that UHMW-PMMA film has a better performance than GMW-PMMA using in the dental material.
