Thermal expansion behavior of nylon 6 nanocomposites

The linear thermal expansion behavior of nanocomposites was measured and compared with the theory by Chow. Nanocomposites were prepared by melt mixing organically modified montmorillonite with high and low molecular weight (LMW) grades of nylon 6 using a twin screw extruder. Thermal expansion measurements were made on samples taken from injection-molded Izod bars in the flow direction (FD), transverse direction (TD), and normal direction (ND)....
