Commercially available polyamide(PA) thermoplastic elastomer(TPE), namely PEBAX4033 was blended with inorganic hybrid filler which was prepared by reaction between polyhedral oligomeric silsesquioxane (POSS) containing amino group and toluene diisocyanate(TDI)-caprolactam(CL) to explore the effect of blending the filler with the TPE. The chemical structure of the filler was identified by using FT-IR and 1H-NMR. The composites, PEBAX4033/POSS-(TDI+CL), fabricated by blending TDI modified POSS filler with PA-TPE up to 7 wt%, showed better elastic recovery, lower permanent setting, and similar ultimate elongation comparing to the original elastomer and the PEBAX/octaphenyl POSS blend. Also, the tensile strength and the initial modulus increased with increasing the hybrid filled content. Consequently the POSS-(TDI+CL) filler is a suitable material for enhancing strength and modulus without damage on the elastic properties of the original TPE. |
