Effect of the Addition of Nano-Clay on the Physical Property and the Melt-Spinnability of Bacterial Polyester

Abstract:

Synthetic mica organically treated with alkylamines was added to poly (3-hydroxybutyrate-co-3hydroxyhexanoate) (PHBH), one of the bacterial co-polyesters. Mica dispersing in PHBH acted as a crosslinking point of PHBH chains and increased the melt viscosity of PHBH significantly. The melt spinnability of PHBH was greatly improved by the addition of mica and the crystallization of PHBH in the spinline was highly promoted. WAXD spectra showed that the as-spun fibers of PHBH/MICA contain both highly oriented α-and β-forms of PHBH crystal. Further the SAXS revealed that the mica dispersing in the PHBH fiber oriented with its surface parallel to the fiber axis. The crystalline orientation of PHBH, orientation of mica, and the formation of β-form all improve the mechanical property of PHBH fibers.
