Abstract
This article deals with the analyses of the effect of halloysite nanotubes (HNTs) and modified HNTs (mH) with minimal loading on the properties of syndiotactic polystyrene (sPS)/liquid crystalline polymer (LCPs) blends. Modification of HNTs with N-(β-aminoethyl)-γ-aminopropyl-trimethoxysilane (APTMS) is confirmed by Fourier Transform Infrared Spectroscopy (FTIR), Transmission Electron Microscopy (TEM) and X-ray Diffraction (XRD) studies. Intensification of crystallinity of the thermoplastic blends due to induced nucleation by the halloysite nanotubes are corroborated by XRD as well as Differential Scanning Calorimetry (DSC). Due to favorable LCP fibrillations, nanocomposites exhibited higher dynamic mechanical properties than the matrix polymer as observed from the Dynamic Mechanical Analysis (DMA). Rheological properties of the blends were upgraded whereas; the chain orientations along with their alignments were highly influenced by both unmodified and modified HNTs. Modification of HNTs brings compatibility in between the blend partners revealing improved crystallization, morphological, rheological, and thermo-mechanical properties relative to that of pure matrix.
