On-line optical monitoring of nanocomposite compounding

摘要

On-line monitoring of compounding of PA6 with nanoclay is examined to investigate the level of exfoliation and degradation under a variety of conditions in real-time. On-line rheological and optical reflectance measurements are compared with off-line analyses of compounded samples to investigate the relationship between these readings and exfoliation/intercalation and/or degradation of the nanocomposite. The effect of the processing (twin-screw/single-screw, temperature and screw speed) on the resulting melt quality and the ability to assess this quality in real-time is discussed.
