“…So far, many nucleators have been incorporated into PES to present relatively good nucleation effects on the PES. These nucleators not only increase the crystallizability and tailor the melt‐crystallization behavior/crystallization kinetics, crystal morphology, microstructure and enzymatic hydrolysis rate, but also improve the comprehensive mechanical properties of PES 17–27 . It has been reported that some nucleators exhibit uncontrolled crystal morphology and a limited nucleation effect due to agglomeration or uneven distribution in the PES matrix, resulting in undesirable physical properties and unsatisfactory comprehensive performance.…”

A P‐ and Zn‐containing organic/inorganic hybrid layered metal phosphonate (PPZn) as a biocompatible nucleator was incorporated into biodegradable poly(ethylene succinate) (PES) polyester to investigate the effect of the PPZn on the crystallization behavior, crystal and aggregated structure, crystal morphology and thermal stability of the PES. Two traditional inorganic nucleators (Talc and BN) were utilized for comparison with the PPZn. The PPZn exhibited markedly higher nucleation effect than the Talc and BN. The PPZn significantly enhanced the Tc and crystallization rate, and shortened the crystallization time of the PES, as confirmed by the crystallization kinetics. Hydrogen bond interaction exists between the PPZn and PES C=O group and between the PPZn and PES amorphous C–O–C group, which facilitates the uniform dispersion of the PPZn in the PES matrix. The nucleation of the PES is mainly attributed to good crystal lattice matching between the PES and PPZn. The PPZn slightly increased the thermal degradation temperature of the PES below 380 °C. © 2021 Society of Chemical Industry

“…Properties which have shown substantial improvements due to the incorporation of nanoparticles include mechanical properties, e.g., strength, modulus and dimensional stability, electrical and thermal conductivities, permeability rates of gases, water and hydrocarbons, flame retardancy, smoke emissions and thermal stability [7e9]. Furthermore, the addition of nanoparticles can also have a significant influence on the crystallinity, spherulite size, and lamellar structure of the polymer [10,11].…”

“…Only limited work currently exists on the properties of isotropic blends of CNTs with, mainly, poly(ethylene terephthalate) [13][14][15][16][17][18][19], poly(butylene terephthalate) [20], and poly(butylene succinate) [21] matrices. Finally, the only existing studies on poly(ethylene succinate)/multi-wall carbon nanotube (PESu/ MWCNT) composites involve composites prepared with the method of solution casting [22][23][24]. More importantly, we find no reports in the open literature on how the exposure to an external electric field can change the filler structure and physical properties of such composites.…”

The effects of electric fields on the filler response dynamics and electrical percolation of poly(ethylene succinate)/multiwall carbon nanotube (MWCNT) composites are studied. When subjected to AC electric fields in their melt state, PESu/MWCNT composites exhibit dramatic improvements in their transverse electrical conductivity. More importantly, the elevated conductivity values are preserved after matrix solidification. Overall, the experimental results show that the electrified composites exhibit the same electrical conductivity levels as their non‐electrified counterparts at approximately threefold less filler content. The dynamics of the insulator‐to‐conductor transition under an electric field also are studied for these composites and correlate reasonably well with operating parameters, such as electric field intensity, matrix viscosity, and filler content through a relatively simple model. Such a model can serve as an enabling tool in the determination of process conditions for the manufacturing of electrically conducting MWCNT/polymer composites. POLYM.
