ABSTRACT
A new approach to
improve the thermal stability and mechanical strength of thermoplastic polyester elastomer (TPEE) using spodumene slag as the filler is reported here. The
thermal decomposition temperature of TPEE increases from 277 oC to about 350 oC by
about 26% in the presence of pristine spodumene slag. The surface graft reaction further improves its barrier effect. Besides, spodumene slag can be used
as good reinforcement to TPEE, and also the surface
treatment favors further improvement of its reinforcing effect. But the presence of spodumene slag reduces elastoplasticity and viscoplasticity of system,
leading to decreased tensile cycles and elongation levels. The morphological and
crystallographic methods were then employed to further reveal the alteration of
phase separation structure of TPEE in the presence of spodumene slag, aiming at
establishing structure-property relations of composites. This work can provide
useful information on the preparation of new TPEE composites with tailorable
properties.
