“…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

“…The result indicated that the addition of 0.5% and 1% POSS to the base polymer increased the modulus, strength and elongation-at-break of the PUs compared to that without nano-particles. By addition of 0.5% nano-particles, there was greater improvement in the strength and elongation-at-break, compared to that of 1% nano-particles (Teng and Qiu 2017 ).…”

“…Various studies, including that by Teng and Qiu research in 2016, demonstrated that the addition of a small amount of POSS has led to mechanical properties’ improvement. Teng and Qiu 2017 introduced 0.5 wt% and 1 wt% of POSS into polyethylene succinate structure using a common solvent between nano-particles and polyethylene succinate. The result indicated that the addition of 0.5% and 1% POSS to the base polymer increased the modulus, strength and elongation-at-break of the PUs compared to that without nano-particles.…”

Three polyurethane formulations were prepared on the basis of siloxane; two formulations contained 1% and 3% of a hydroxyl functionalized polyhedral oligomeric silsesquioxane [POSS (ROH)2] nano-particles (as a co-chain extender) and one was without nano-particle. Structures of the polyurethanes were characterized by FTIR and SEM. The effect of POSS nano-particles on properties of the synthesized PUs was examined for vascular applications by tensile test, contact angle, SEM, AFM and endothelial cells viability evaluation. Properties of the polyurethane with 1% POSS were compared with those of PU without POSS and the results showed 66% increase in the elongation-at-break, 53% increase in tensile strength and 33% increase in modulus, 9.45% increase in contact angle, 76.7% reduction in surface roughness and 9.46% increase in cell viability. It was also shown that a polyurethane containing 1% of POSS nano-particles in its structure developed the highest hydrophobicity, which resulted in its lowest potential for thrombosis.Graphical Abstract

“…In the presence of the NA, many polymeric materials exhibit the improved physical properties and tailored performances. To date, many NAs have been incorporated into the PES to manipulate the crystallization/melting behavior, crystal morphology, microstructure and enzymatic hydrolysis rate, enhance thermal stability and improve mechanical properties of the PES [17][18][19][20][21][22][23][24][25][26][27]. Among the NAs aforementioned, some inorganic NAs show the agglomeration morphology and weak interfacial strength/interaction with the PES, resulting in the uncontrolled crystal shape, undesirable or relatively poor physical properties and performances of the composite.…”

A linear diamides derivative (TMC300) as a nucleating agent (NA) was incorporated into biodegradable poly(ethylene succinate) (PES) to investigate effect of TMC300 on nucleation, crystallizability, crystallization kinetics, aggregated structure of PES. TMC300 enhanced significantly crystallizability and crystallization temperature of PES in cooling process at a rate of 10 ℃/min from molten state, indicating that TMC300 exhibits an excellent nucleation effect on PES. IR measurement suggested that TMC300 interacts with amorphous carbonyl and ester group, and crystalline CH2 group of PES via hydrogen bond. Change rate of carbonyl group is comparable to that of C‒C backbone of PES, regardless of the presence or absence of TMC300. Small difference of diffraction peak in WAXD measurement between neat PES and PES/TMC300 is probably attributed to spherulitic orientation on film surface of neat PES, and different spatial arrangements in the same crystal lattice. TMC300 enhanced carbon residue yield of PES/TMC300 composite, probably related to slight flame retardance effect.
