Cellulose blends from gel extrusion and compounding with polylactic acid

Cellulose, dissolved in ionic liquids (IL), can be used successfully the processing of thermoplastics. To recover liquid while maintaining thermoplastic properties, other spacers than IL might introduced into cellulose network. Such blend materials have been prepared before by solution blending as reported literature. In this study, preparation and investigation polylactic acid (PLA) blends using an extrusion process with co-solvent for intermediate compatibilization is reported. The obtained transparent films show a homogeneous morphology without phase separation. Thermal analysis showed no separated glass transition PLA, FTIR hydrogen bonding between PLA chains. stability degradation onset around 270°C lies regenerated pure PLA. tensile strength elongation ~40 MPa 1.3%, respectively, were comparable to multiphase composite containing twice molecular weight Generally, mechanical performance was strongly influenced reactions mainly caused used, well morphology. study shows that transfer from generally possible obtain novel blends.
