| Abstract: | Polyurethane (PU) based on polycaprolactone (PCL) and 4,4′ diphenyl methylene diisocyanate (MDI) was synthesized using a two-step
method. The PU obtained was then blended with various amounts of cellulose extracted from alfa stems to prepare composite
materials. The influence of cellulose on the thermal and mechanical properties of different composites was demonstrated by
means of several characterization techniques such as Fourier transform infrared spectroscopy (FTIR), differential scanning
calorimetry (DSC), scanning electron microscopy (SEM)… |
