| Abstract: | A series of poly(propylene carbonate)/halloysite nanotube(PPC/HNT) composites were prepared by melt blending in the presence of 2,4-toluene diisocyanate(TDI) as a coupling agent.The mechanical property,thermal property and their morphology were investigated by tensile tester,thermogravimeter and scanning electron microscope.Tensile test results show that with the introduction of TDI,tensile strength of the composites increases while elongation at break decreases significantly.Thermogravimetric analysis(TGA)curves indicate that thermal stability improves slightly compared with the that of composite without TDI.Scanning electron microscope(SEM) images illustrate that the interfacial compatibility between PPC and HNT is improved by the addition of TDI. |
