“…The chain extender could be used as an interfacial compatibilizer between two incompatible phases. [37,38,39] Figure 2a shows the FTIR spectra of PBAT, PPC, Jc-ADR, Pr-GO, and PBAT/PPC/PrGO nanocomposites with various PrGO contents. The terminal carboxyl and hydroxyl groups of PBAT and PPC could react with the epoxy groups of Jc-ADR to form branched or crosslinked structures.…”

Poly(butylene adipate‐co‐terephthalate) (PBAT) nanocomposites with poly(propylene carbonate) (PPC) and graphene oxide (GO) are fabricated by melt blending. A dual‐continuous network structure is obtained via adding reactive compatibilizer and nanofillers, which not only dramatically reduce the conductivity percolation threshold of nanocomposites but also improve its mechanical properties. The compatibility of PBAT and PPC is improved owing to the partial thermally reduced GO (PrGO) with the residual oxygen‐containing functional groups on its surface. The epoxy groups of the reactive compatibilizer (Jc‐ADR) react with the terminal groups of polymers to increase the interfacial adhesion. The characterization analysis by morphology, rheology, mechanics, DMA, and conductivity indicates that the formation of the dual‐continuous network is attributed to the synergistic effect of PrGO and Jc‐ADR. Furthermore, a remarkable enhancement in barrier properties is obtained with the addition of PrGO. Compared with PBAT/PPC blends, the water vapor permeability (WVP) decreases by nearly 1 order of magnitude after adding 1.0 wt% PrGO. This will offer a possibility for the development application of PBAT and PPC in a barrier and antistatic packaging field.

“…These properties have made PBT an irreplaceable plastic material in industrial applications, however, the notch sensitivity and poor notched impact performance of PBT hinders its 1 function in some industrial applications. [3][4][5][6][7] In recent years, considerable research studies have been accomplished to enhance the notch impact performance of PBT. One of the most widely reported effective methods is melt-blending PBT by an elastomer such as ethylene/vinyl acetate copolymer (EVA), poly(ethylene-octene) (POE) and glycidyl methacrylate grafted POE (POE-g-GMA), thermoplastic polyurethane (TPU), and ethylene-propylene-diene (EPDM).…”

In this paper, fracture toughness evaluation of polybutylene terephthalate (PBT)/thermoplastic polyurethane (TPU) binary blends and PBT/TPU/carbon nanotubes (CNTs) ternary nanocomposites have been conducted using both Izod impact and quasi-static fracture tests. Essential work of fracture (EWF) approach is used to study the fracture properties in details. The results of EWF tests revealed an effective role of TPU and CNTs in toughening mechanism of binary blends and ternary nanocomposites. According to EWF results, both the crack resistance and plastic deformation energies promoted in all compounds as compared to neat PBT. Energy dissipation in the yielding and tearing stages determined by the energy partitioning method. The obtained results indicated that displacement up to the failure point increased by increasing the TPU content, while inclusion of CNTs reduced this quantity. The specific non-essential work of fracture [Formula: see text] , [Formula: see text], and [Formula: see text] increased with increasing the TPU contents which is confirmed by load-displacement curves. Whereas, addition of CNTs reduced [Formula: see text] and [Formula: see text] values as compared to reference binary blend, however, ternary nanocomposites still have higher values as compared to pure PBT. In contrast with EWF results, high strain rate of impact test prevents the activation of toughness improving mechanisms that readily occurs in quasi-static loading.

“…On the other hand, it can also solve the issue of low PET crystallization rate. [12,[14][15][16][17][18][19] There are several methods for producing PET/CNT nanocomposites including; in situ polymerization, direct mixing, solution method, which melt compounding is the most utilized method in the industry. [2,20,21] The principal problem of this method is the high temperature of the process, which causes two types of degradation reactions in PET chains and leads to chain breakage, reduction of molecular weight, and descension of mechanical and rheological properties: (1) Thermal degradation that leads to the formation of smaller chains with terminal groups of vinyl ester and carboxyl and (2) hydrolysis that brings about smaller chains with the end groups of hydroxyl ester and carboxylic.…”

Thermal degradation of polyethylene terephthalate (PET)/carbon nanotube (CNT) nanocomposites is a serious issue in the manufacturing process of this nanocomposite that can limit the applications of the nanocomposite. In this study, the effects of two kinds of chain extenders, pyromellitic dianhydride (PMDA) and pentaerythritol (PENTA), on the rheological behavior, thermal characteristics, and crystallinity of the PET were investigated. The results of shear rheology revealed improvement of the storage modulus and complex viscosity, which indicated the recoupling of broken chains, increasing the chain length, and the generation of long branches was the reason for chain extension. Also, differential scanning calorimetry (DSC) results clarified an increase in PET crystallization rate in the presence of CNT and chain extenders. Furthermore, SEM was performed to detect CNT dispersion in the nanocomposite, and four-probe technique test was utilized to determine the influence of CNT on the electrical properties of PET.
