“…Here, the samples (PBS, PBSMS-0.95, PBSMS-0.89, PBSMS-0.83, and PBSMS-0.52) are named with the molar fractions of butylene succinate (BS) repeating units in the copolymer chains determined from NMR results. As noted in the previous studies, co-feeding of two types of monomers using the same polycondensation procedure tends to produce a nearly random distribution of the two repeating units in the copolymer chains. ,− The atacticity of all of the copolymers, obtained from 13 C NMR spectra (JEOL, ECA-600M), was nearly 1 (see Table S1), indicating random copolymerization of succinic acid and methylsuccinic acid with butanediol.…”

“…Poly(butylene succinate) (PBS) and the poly(butylene succinate- co -butylene 2-methylsuccinate) (PBSMS) random copolymers were synthesized from 1,4-butanediol, succinic acid, and 2-methylsuccinic acid using various feeding molar ratios via a two-step reaction of esterification and polycondensation in the molten state. The detailed description of the chemical synthesis is reported in the literature. − The number-average and weight-average molecular weights ( M n , M w ) and the thermal properties of the samples were determined by gel permeation chromatography (Waters-1515) and a differential scanning calorimeter (TA equipment, Q2000), respectively. The results are listed in Table S1 in the Supporting Information.…”

Determination of the Critical Size of Secondary Nuclei on the Lateral Growth Front of Lamellar Polymer Crystals

Nucleation is the rate-limiting first step of crystallization. The energy barrier related to form the critical nucleus predominantly affects the nucleation rate. Determination of the size of the critical nucleus is a key for understanding the mechanism of nucleation and allows testing theories. However, it has been a great challenge for both experimentalists and theorists to quantify this size. In this work, we propose a method for computing the size of critical secondary nuclei formed on the lateral growth front of lamellar crystals of folded polymer chains. For secondary nucleation of random copolymers, the exponent in a power-law relation between the spherulitic radial growth rate and the content of crystallizable units is related to the number of repeating units within the critical secondary nuclei. For miscible blends of crystallizable and amorphous polymers, the spherulitic radial growth rate as a function of the volume fraction of crystallizable polymer chains also follows a power-law relation with the exponent related to the number of polymer chains in each critical secondary nucleus. Based essentially on the stochastic nature of the nucleation process of random copolymers and polymer blends during crystallization, this approach does not require the prior knowledge on the detailed nucleation pathway and folding conformation. Presenting results for poly(butylene succinate), its random copolymers and blends, we show that a critical secondary nucleus consists of 15–27 butylene succinate units, corresponding to five to eight stems when the polymers were isothermally crystallized from a quiescent melt at temperatures ranging from 70 to 95 °C. These stems in a critical secondary nucleus are derived from one or two polymer chains. Our results contest the classical Lauritzen–Hoffman theory, which expects that the critical secondary nucleus is formed by a single stem. The approach presented here can be generally applied to the lamellar crystals of other crystallizable flexible polymers. In addition, our approach is not limited to secondary nucleation and can be adopted for primary nucleation as well.

“…Han et al studied the enzymatic degradation behavior for different poly(butylene succinate-ran-butylene 2-methylsuccinate) (PBS-ran-PBMS) copolyesters, reporting higher degradation rates for those copolymers with a higher PBMS content. Considering the copolymer with 20% mol in PBMS, the hydrolytic degradation (without the enzyme) showed a negligible weight loss compared to that of the enzymatic degradation (amano lipase from Pseudomonas fluorescens), achieving a 30% weight loss in 300 h [155].…”

A Review on Current Strategies for the Modulation of Thermomechanical, Barrier, and Biodegradation Properties of Poly (Butylene Succinate) (PBS) and Its Random Copolymers

The impact of plastics on the environment can be mitigated by employing biobased and/or biodegradable materials (i.e., bioplastics) instead of the traditional “commodities”. In this context, poly (butylene succinate) (PBS) emerges as one of the most promising alternatives due to its good mechanical, thermal, and barrier properties, making it suitable for use in a wide range of applications. Still, the PBS has some drawbacks, such as its high crystallinity, which must be overcome to position it as a real and viable alternative to “commodities”. This contribution covers the actual state-of-the-art of the PBS through different sections. The first section reviews the different synthesis routes, providing a complete picture regarding the obtained molecular weights and the greener alternatives. Afterward, we examine how different strategies such as random copolymerization and the incorporation of fillers can effectively modulate PBS properties to satisfy the needs for different applications. The impact of these strategies is evaluated in the crystallization behavior, crystallinity, mechanical and barrier properties, and biodegradation. The biodegradation is carefully analyzed, highlighting the wide variety of methodologies existing in the literature to measure PBS degradation through different routes (hydrolytic, enzymatic, and soil).

Due to their complete non-biodegradability, current food packages have resulted in major environmental issues. Today’s smart consumer is looking for alternatives that are environmentally friendly, durable, recyclable, and naturally rather than synthetically derived. It is a well-established fact that complete replacement with environmentally friendly packaging materials is unattainable, and bio-based plastics should be the future of the food packaging industry. Natural biopolymers and nanotechnological interventions allow the creation of new, high-performance, light-weight, and environmentally friendly composite materials, which can replace non-biodegradable plastic packaging materials. This review summarizes the recent advancements in smart biogenic packaging, focusing on the shift from conventional to natural packaging, properties of various biogenic packaging materials, and the amalgamation of technologies, such as nanotechnology and encapsulation; to develop active and intelligent biogenic systems, such as the use of biosensors in food packaging. Lastly, challenges and opportunities in biogenic packaging are described, for their application in sustainable food packing systems.
