The aim of this study is to investigate the film blowing processing of various polyamide 6-based layered silicate nanocomposites (LSN’s) and to correlate their processing behaviors to the underlying rheology and structure. In-situ polymerized nanocomposites were found to possess a wider processing window compared to the base PA6. Shear and dynamic rheological measurements were employed to correlate the rheological behavior of the nanocomposites to the bubble formation and stability in the film blowing process. The in-situ plymerized LSN melts having higher elastic modulus (G′) were found to perform better in the film blowing process. DSC measurements indicated that nanoclays induce the γ type of crystallinity, which may also play a role in film blowing behavior.

Sodium Fluosilicate

The structure of sericite is stable, and it is hard to prepare polymer layered silicate nanocomposites (PLSN). Therefore, structural modification was employed to activate sericite to reduce the layer charger. The thermal treated sericite (S1) was prepared by thermal modification at 800 for one hour. Then, the resulting product was modified with sodium fluorosilicate, whose effect was characterized by X-ray diffraction (XRD) analysis. The dissolving-out amount of Al3+ of salt-treated product (S2) reached circa 2.55 mg/g at the optimal processing conditions. CEC of S2 was increased to 10.52 meq/100g compared with that of original sericite (4.94 meq/100g). The results of XRD analysis indicated that mica-type phase persisted after salt modification with sodium fluosilicate.
