Lignin Composites with Phenol-Acrylates Cured by Electron Beam

As the major by-product of the pulp and paper industry, determining a use for lignin represents a key priority to almost any bio-materials research organization. The purpose of this study is to investigate the interaction with and effects of lignin within phenol- acrylate composites cured by electron beam, characterizing changes to both physical and chemical properties. In order to more fully characterize the effects of lignin, results of pure lignin as well as cellulose samples subjected to electron beam radiation and tested by FT-IR are presented. For the composite material, results of both DMA and FT-IR spectroscopy will be presented. Results of these analyses are then be discussed and the impact of lignin on the chemical changes within the resulting composite identified.
