Abstract
The physical properties of nylon-66 containing clay nanoparticles (5 wt%) were investigated in terms of mixing rate (15-90 rpm) and mixing time (5-30 min) at the given apparent shear (rpm x mixing time) during melt compounding. The WAXD patterns of all the nylon-66/clay nanocomposites revealed that the nanoparticles were fully exfoliated. At the given apparent shear, the dynamic viscosity and storage modulus of nylon-66/clay nanocomposites were increased as mixing rate was increased. In the log G′ - log G′′ plot, the nanocomposites prepared at higher mixing rate gave smaller slope and inflection point at higher loss modulus. Clay nanoparticles played a role of nucleating agent for nylon-66 by increasing crystallization temperature, which was more pronounced at lower mixing rate. The induction time during isothermal crystallization under shear at 235 ℃ was shorter for the nanocomposites prepared at lower mixing rate.
