Nylon 6/organoclay(OC)nanocomposites were processed by melt intercalation with AA as compatilizer.The microstructure of nylon 6/OC nanocomposites was investigated by X-ray diffraction(XRD).The dependences of mechanical properties

heat distortion temperature and water barrier properties were investigated on the content of compatilizer and clay

respectively.The XRD analysis results show that PA6/OC nanocomposites have formed intercalated(partial exfoliated) structure.The nylon 6/OC nanocomposites exhibit significant improvement in mechanical properties

thermal properties

and barrier properties comparing with neat nylon 6.When the content of AA is 2/3 parts per hundreds of resin(phr)

the loading of clay is 4 phr

there is 34% improvement in the tensile strength

18.2 ℃ improvement in the heat distortion temperature

and 0.6% decrement in water absorbing capacity of PA6/OC nanocomposites.
