Preparation and Characterization of Poly(trimethylene terephthalate) Nanocomposites

Abstract

Intercalated nanocomposites comprising poly(trimethylene terephthalate) (PTT) synthesized from 1,3-propanediol (PDO) and terephthalic acid (TPA) incorporated between clay layers were generated by means of in situ interlayer polymerization. The thermal stabilities, mechanical properties, and morphologies of PTT hybrids made with two different organoclays were compared. 1,2-Dimethylhexadecylimidazolium-montmorillonite (IMD-MMT) and dodecyltriphenyl-phosphonium-montmorillonite (C12PPh-MMT) were used as reinforcing organoclay fillers in the fabrication of the PTT hybrid fibers. The variations in the properties of the nanocomposites were discussed with respect to the organoclay content in the polymer matrix and the draw ratio (DR). The thermomechanical properties and morphologies of the PTT hybrid fibers were characterized using differential scanning calorimetry, thermogravimetric analysis, wide-angle X-ray diffraction, electron microscopy, and mechanical tensile properties analysis. Observation of the nanostructures of the hybrid fibers via scanning and transmission electron microscopy demonstrated that the clay layers were well dispersed in the matrix polymer, although some clusters or agglomerated particles were also detected. The addition of only a small amount of organoclay was sufficient for improving the thermal stability and mechanical properties of the PTT hybrid fibers.
