“…Mechanical properties of polyethylene terephthalate-isophthalic acid-polyethylene glycol (PET-IP) with nanoclay series.to the results observed in various other types of PET clay nanocomposites[32][33][34][35]. The improvement in tensile properties was attributed to the nanolevel dispersion of clay layers in the polymeric matrix.…”

This paper examines the influence of nanoclay on the structure, thermal and mechanical and gas barrier properties of a polyethylene terephthalate (PET)-based copolyester using a new modified formula. The copolyester considered in this work consists of partially replaced acid and diol monomers in main chain PET polymers, namely, polyethylene glycol (PEG) and isophthalic acid monomers, i.e., PET-IP. Nanoclays were filled from 0-3 wt% in PET-IP using the melt mixing method. The structural examination of composites tested by X-ray diffraction (XRD) and transmission electron microscopy (TEM) revealed the distribution of nanolayers of clay particles in polymeric matrix. Up to 1 wt% nanoclay in PET-IP, an exfoliated structure resulted and above 1 wt% nanoclay an intercalated structure resulted. It was observed that 0.5 wt% nanoclay filled PET-IP resulted in improved nucleation characteristics and above 0.5 wt% nanoclay dramatically increased the gas transport (CO 2 , O 2 , N 2 and water vapor), thermal and mechanical properties. The results also showed that the distribution of nanoclays affected the gas barrier properties of the polymer and can be controlled by processing parameters.

“…[24][25][26][27] Therefore, much effort is necessary devoted to improve the dispersibility of the MMT through organo-or nano-modication of MMT. [28][29][30] To design an efficient triazine-rich ame-retardant and to study the effect of their wrapped structure on the properties of PBT composites is of great signicance for promoting the development of this eld. For example, higher ame retardancy obtained and the mechanical properties improved, which can be attributed to the good interfacial adhesion between wrapped MMT and the polymer matrix.…”

A novel flame retardant (PTAC-MMT) was prepared by wrapping montmorillonite (MMT) with poly(2,4,6-triallyloxy-1,3,5-triazine) (TAC) via in situ polymerization, and its structure and properties were characterized by Fourier transformed infrared (FT-IR) spectroscopy, 1 H nuclear magnetic resonance ( 1 H NMR) and 13 C NMR, transmission electron microscopy (TEM), X-ray powder diffraction (XRD) and thermogravimetric analysis (TGA) measurements. The PTAC-MMT and aluminum diethylphosphinate (AlPi) were then incorporated into poly(butylene terephthalate) (PBT) to improve the flame retardancy.The sample containing 1.67 wt% PTAC-MMT and 8.33 wt% AlPi had a LOI value of 36.4% and achieved UL94 V-0 classification. The wrapping flame retardants exhibited excellent anti-dripping effect in PBT composite. This work could provide a novel way to prepare modified MMT and the as-prepared flame retardants.

“…It is the most economically viable approach for continuous processes and large-scale uses (Acierno et al, 2011;Engelmann et al, 2013). The particular interest in incorporating nanofillers into PBT is driven by the possibility of accelerating the crystallization process to reduce cycle time and increase productivity for injection molding of PBT (Kalkar et al, 2013). A fast-injection molding cycle is required for high production rates of PBT nanocomposite-based products (Oburoğlu et al, 2012b).…”
