Synthesis and characterization of polyurethane foam with cellulose nanowhisker as a filler / Shafinaz Khaidir Nasation

In this study, there were three stages involved which are acid hydrolysis, preparation of control polyurethane (PU) and polyurethane nanocomposites and the last stages were characterization of polyurethane using Fourier Transform Infrared (FTIR) Spectroscopy and Thermogravimetric Analysis (TGA).
