| Abstract: |
| A PU/organomontmorillonite nano-composite(OMMT) was prepared by in-situ intercalative polymerization.It was found by XRD and TEM analysis that OMMT was completely exfoliated and uniformly dispersed in PU matrix in case of 1% OMMT/PU and 3% OMMT/PU composites.The analysis showed that the heat resistance of the nano-composite improved by adding OMMT.It was indicated by dynamic mechanical analysis that OMMT had little effect on the modulus of PU.All the hardness，elastic modulus，tensile strength and elongation at break of the PU/OMMT nano-composite were higher than those of PU compound. |
