Abstract

Composites from polyethylene and cellulose microfibrils are perceived as a viable alternative over traditional filled polymers in electrical insulation applications, biomedicine, packaging and construction. This interest arises from the remarkable mechanical properties of such microfibrils. Some experimental aspects regarding the preparation and the characterisation of polyethylene composites with cellulose microfibrils are presented in this paper. Morphological changes of polyethylene matrix when microcrystalline cellulose is added are pointed out by electronic microscopy, by mechanical and dielectric characterisation. Polymer composites from polyethylene and cellulose microfibrils show improved mechanical and dielectric properties compared to polyethylene and traditional organic composites..
