A powerful toolbox is needed to turn the linear plastic economy into circular. Development of materials designed for mechanical recycling, chemical and/or biodegradation in targeted end-of-life environment are all necessary puzzle pieces this process. Polyesters, with reversible ester bonds, already forerunners circularity: poly(ethylene terephthalate) (PET) most recycled material suitable and while common aliphatic polyesters biodegradable under favorable conditions, such as industrial compost. However, circular design needs be further tailored different options enable recycling greener conditions rapid enough even less environmental conditions. Here, we discuss molecular polyester chain targeting enhancement circularity by incorporation more easily hydrolyzable additional dynamic or degradation catalyzing functional groups part chain. The utilization replacement current volume plastics also reviewed well embedment green catalysts, enzymes matrices facilitate

Abstract Biofilm formation on food packaging surfaces is a major issue in the industry, as it leads to contamination, reduces shelf life, and poses risks human health. To mitigate these effects, developing smart coatings that can actively sense combat microbial growth has become critical research focus. This study motivated by need for intelligent solutions integrate antimicrobial agents sensors real‐time contamination detection. It hypothesized combining conducting polymers (CPs) with nanomaterials enhance efficacy while maintaining mechanical integrity environmental stability required applications. Through application of numerous technologies like surface modification, CP–nanoparticle integration, multilayered coating, performance sensor capabilities materials were analyzed. Case studies showed 90% inhibition bacterial tenfold decrease viable counts AgNPs incorporation, extending strawberries’ life 40% fish freshness an additional 5 days. Moreover, CP complex systems have been shown reduce oxidative spoilage nuts dried fruits up 85%, quality leafy greens 3 weeks under suboptimal conditions. Environmental assessments indicated 30% reduction carbon footprint when combined biodegradable polymers, contributing more transparent reliable supply chain. CP‐based films integrated exhibit high sensitivity, detecting ammonia concentrations below 500 ppb, offer significant selectivity sensing hazardous gases. These findings indicate markedly safety sustainability

Abstract Cellulose acetate (CA), synthesized by solid–liquid acetylation of low crystalline cellulose (LCCell) obtained cold shearing in a short time under environmentally benign conditions, effectively enhanced the crystallization poly(lactic acid) (PLA). The composite PLA compounded with CA from LCCell exhibited higher crystallinity and flexural modulus than those pristine PLA. CAs recrystallized also improved mechanical strength compounding, but their effects were weaker that LCCell. factor effectiveness is miscibility originating sufficiently released interchain hydrogen bonds fibrils shearing, which allows dissolution macroscopic aggregation chains composite.

Magnetic particle imaging (MPI) is a promising modality nearing clinical introduction. MPI's tracer-based principle allows for highly sensitive background-free imaging. Potential applications include cardiovascular and endovascular interventions. In principle, medical instruments are invisible in MPI due to the missing signal generation. Therefore, permanent marking technologies have been introduced. Additionally, temporary markers of interest follow-up examinations after stent implantation prevent artifacts during postinterventional lumen quantification. Consequently, instrument MPI, based on biodegradable polylactic acid (PLA) superparamagnetic iron-oxide nanoparticles (SPIONs), developed this study. To investigate markers, characteristics degradation over time studied 28 d water bath at 37 °C. The samples analyzed using scale, micro-CT, microscopy, magnetic spectroscopy (MPS), vibrating sample magnetometry (VSM). A continuous mass decrease detected (≈90% d), while MPS data show no loss signal. VSM confirms that markers' reduction can be accounted PLA, SPIONs hardly detach from coating. introduced technology, with its behavior, basis variety anticipated application scenarios.

Fused deposition modeling (FDM) 3D printing (3DP) of PLA biocomposites reinforced with plant-derived cellulosic fibrous materials, including spun yarn, microcrystalline, microfibrillar, nanofibrillar cellulose, and cellulose nanocrystals, offer an environmentally sustainable solution to the mechanical limitations polymer-only printed materials. Micron- submicron-scale fibers are valued for their renewability, non-toxicity, high surface area, favorable elastic specific moduli; notably, micron-scale reinforcements particularly attractive due ease large-scale industrial production commercial viability. Similarly, benefits from production, contributes CO2 sequestration through its raw material precursors, requires less energy than non-biodegradable petroleum-derived polymers. Incorporating these each which offers performance properties, complementary strengths, environmental benefits, as constituent phases in FDM 3D-printed (FDMPBs) can further enhance responsiveness already low-waste 3DP technology. Inspired by compelling advantages, this paper critically reviews research on FDMPB a matrix, uniquely categorizing studies based form reinforcement impact biocomposite’s structure performance. Additionally, review covers biocomposite filament methods equipment involved, presenting alternative framework cataloging research. A comprehensive literature analysis reveals that wide variation feedstocks, fiber–matrix compounding methods, equipment, processing parameters used complicates comparison properties across studies, often resulting conflicting outcomes. Key have been compiled bridge gap more nuanced understanding cause-and-effect relationships governing properties. Finally, targeted recommendations future developing matrix provided, addressing knowledge gaps challenges highlighted peer-reviewed literature.
