Structure and Properties of Organic-Vermiculite/Polyimide Composite Films

Abstract:

A series of organic-vermiculite/polyimide (OVMT/PI) hybrid films were successfully prepared by in situ polymerization using hexadecyltrimethyl ammonium bromide (CTAB) modified vermiculite (VMT) as filler. XRD analysis showed the OVMT were exfoliated in the polymeric matrix below 1.5wt%. The tensile strength and elongation at break increased with the addition of OVMT and up to maximum at 1.5 wt%. The Tgs of the films were nearly 400°C indicating that the incorporation of OVMT did not obviously affect the thermal stability of PI films.
