Semi-interpenetrating network derived from polylactic acid/polyurethane blend and reinforced with celulose nanocrystals

• The current work aims to prepare and characterize bionanocomposites based on cellulose nanocrystals and semi interpenetrating networks prepared from PLA and PU. Nanocrystals were dispersed in PU phase with an innovative, novel method called as co-solvent assisted surfactant-less method. The characterization of the materials was done by tensile testing, differential scanning calorimetry and thermogravimetric analysis. The results were progressive and supported the premise that SIPNs are a viable option to prepare mechanically enhanced hybrid matrix that can impart improved mechanical properties to nanocomposites. Additionally, the dispersion method produced excellent dispersion of nanocrystals in the polyol phase, which was successfully transferred to the nanocomposite
