Abstract
SummarySyndiotactic polystyrene (sPS) generally exhibits five crystal modifications (α, β, γ, δ and ϵ) with different molecular conformations and also with different chain packing structures. Among these modifications, the δ phase of sPS is very promising as it absorbs guest molecules producing clathrate or intercalate co‐crystals of sPS. In this connection, sPS/poly(3‐hexyl thiophene) (P3HT) composites have been prepared with the expectation of formation of P3HT nano‐crystal in the crystalline lattice of sPS. Composites have been characterized by UV‐Vis, XRD, TGA studies. Mechanical and morphological properties have been explored. UV spectra show the appearance of vibronic structure of P3HT even at low concentration of P3HT, indicating the formation of nanoaggregates of P3HT in the sPS matrix. FESEM and HRTEM analysis reveal the formation of fibrillar morphology of composites and EDX studies indicate the presence of P3HT in the fiber as well as the interaction between sPS and P3HT. There is enhancement of diameter of sPS/P3HT fibers as well as increase of mechanical strength of fibers.
