N2 - Polymers play a prominent role in our daily lives, however there is a growing concern on the depleting fossil resources triggering the effort to search for their sustainable substitutions. Here, we prepared novel wholly biobased nanocomposites from polyamide 36,36 (PA36,36) thermoplastic elastomer and cellulose nanocrystals (CNCs). The influence of CNC addition and CNC loading on the morphological features, thermal and mechanical properties of PA36,36 was studied. The presence of CNC in PA36,36 affected the thermal degradation of PA36,36. The additions of 10 wt.% and 30 wt.% CNCs to the PA36,36 improved the tensile strength and Young's modulus by up to 700% and 750% to 9.6 MPa and 6.8 MPa, respectively, while still maintaining relatively high elongation at break values. The hardness of the polymer increased significantly after the inclusion of CNC. The PA36,36/CNC nanocomposites also showed relatively good resilience when exposed to 100% strain. Overall, these biobased thermoplastic elastomer nanocomposites could be potential alternatives for some existing rubbers with low or medium hardness.
