摘要
In this study,a facile and environmentally friendly method with low energy consumption for preparing nanoscale AgCl and BaSO4 co-precipitates(AgCl@BaSO_(4) co-precipitates)was developed based on the metathetical reaction.Then,the dried co-precipitates were melt-compounded with polyamide 6(PA6)resins at a specified mass ratio in a twin-screw extruder.The results demonstrated that in the absence of any coating agent or carrier,the nanoparticles of AgCl@BaSO_(4) co-precipitates were homogeneously dispersed in the PA6 matrix.Further analysis showed that after the addition of AgCl@BaSO_(4) co-precipitates,the antibacterial performance,along with the flame-retardance and anti-dripping characteristics of PA6,was enhanced significantly.In addition,the PA6 composites possessed high spinnability in producing pre-oriented yarn.
