Three formulations were prepared: rPET with 4.5wt% ZnPi (ZnPi45), 4.5 wt% ZrP (ZrP45), and a hybrid containing 2.25wt%ZnPi+2.25wt%ZrP (BL225). Rheological analysis confirmed that no premature crosslinking occurs at processing temperature (265°C), indicating that char formation originates from thermally activated degradation chemistry. Thermogravimetric analysis (TGA) under air revealed that ZnPi promotes phosphorus-assisted charring during the primary degradation window (370–470°C), while ZrP enhances residue persistence above 600°C. The hybrid BL225 exhibited an extended degradation width (ΔT10–90 = 182.07°C) and positive synergy indices of approximately 20% at 500°C and 800°C, confirming cooperative interactions. Raman spectroscopy, analyzed using three independent crystallite size calculation methods (Tuinstra–Koenig, Cancado, and Ferrari–Robertson), consistently ranked the structural order as ZnPi45>BL225>ZrP45>rPET. ZnPi45 achieved the largest crystallite size (La = 59.9 nm by Cancado method), while BL225 retained over 85% of this efficiency at half ZnPi loading. These results quantitatively support a cooperative condensed-phase mechanism in which ZnPi generates phosphorus-rich crosslinked networks and ZrP provides a thermally stable inorganic scaffold, collectively forming a dense, oxidation-resistant protective char.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"311 8","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.70275","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148753548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, PLA shows limited biodegradability outside industrial composting, especially when dispersed in the environment. Blending PLA with polyhydroxyalkanoates (PHAs) is a promising strategy to improve its degradation behavior. In this work, fully amorphous blends of amorphous PLA and amorphous poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (aPHA) were studied, with aPHA as the minor component at 10–30 wt.%. The blends were compounded at 185°C. TEM analysis revealed an immiscible morphology with dispersed spherical aPHA domains of 400–600 nm. All blends were successfully foamed by batch pressure-drop foaming using supercritical CO2. Foam density and morphology depended strongly on foaming pressure and temperature. The lowest density, below 50 g/L, was achieved at 50°C and 90 bar, producing a closed-cell structure with cell sizes of 40–80 µm. Biodegradability under simulated home-composting conditions at 30°C was assessed by respirometry, NMR, SEC, and SEM, showing enhanced PLA degradation and total mass loss up to 84% after 4 months. In marine conditions, degradation was limited and mainly selective for aPHA.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"311 8","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.70318","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148753564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of gas sensors, particularly chemiresistive gas sensors, which detect gases based on changes in electrical resistance has particularly gained attention due to their exceptional sensitivity and compact size. The performance of these sensors is greatly influenced by the fundamental properties of materials chosen to act as the sensing layer. The integration of inorganic materials with conducting polymers has become more popular in improving the sensitivity, selectivity, stability, and response kinetics of these sensors. Moreover, these composites address the impact of high operating temperature and humidity. This review focuses on the recent developments in the creation of conducting polymer composites for gas-sensing applications, particularly composites comprising conducting polymers and metal oxides. These composite materials ensure the accurate detection of reducing or oxidizing gases in a variety of environments and can potentially be used in monitoring hazardous gaseous substances in the environment.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"311 8","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.70312","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148696128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The TiO2/Poly(Ani-co-Cz) nanocomposite was characterized, revealing a band gap energy (Eg) of 3.06 eV, calculated using Tauc's equation. Under natural solar irradiation, the nanocomposite with an optimal TiO2/Poly(Ani-co-Cz) ratio of 5 achieves up to 99% MB degradation, exceeding pristine TiO2 by over 33%. This improvement is attributed to enhanced charge separation and light absorption induced by the conductive copolymer. Photocatalysis kinetics were evaluated using the Langmuir–Hinshelwood model, and potential mechanisms were examined through hydroxyl radical trapping experiments. The pseudo-first-order rate constant (kapp) for MB photodegradation was found to be 0.0301 min−1, indicating strong compatibility with pseudo-first-order kinetics. The study confirms the generation of hydroxyl (OH•) and superoxide (O2•−) radicals during dye degradation by the nanocomposite. Antibacterial testing revealed strong inhibition against Bacillus subtilis, a moderate effect against Staphylococcus aureus, minimal impact against Escherichia coli, and a negligible effect against Pseudomonas aeruginosa. These findings indicate that the TiO2/poly(Ani-co-Cz) nanocomposite is a promising dual-function material for solar-driven, sustainable water treatment, enabling simultaneous photocatalytic pollutant removal and antibacterial action.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"311 8","pages":""},"PeriodicalIF":5.2,"publicationDate":"2026-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.70311","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148695906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lignin depolymerization is carried out according to a range of suitable conditions reported in the literature, optimizing the process by investigating the effect of solvent type, solvent-to-glycerin ratio, catalyst type, and concentration. The results show a liquefaction yield up to 90% with a solvent mixture containing glycerin between 30 and 50% w/w. On the other hand, the nature of the catalyst used in the liquefaction poses some limitations, as the use of H2SO4 has to be restricted to 1% w/w to limit the acidity of the derived polyols, reducing the yield, while NaOH increases the final hydroxyl number (nOH) of the product mixture, but still maintaining a very high yield (98%). The polyols obtained under optimized liquefaction conditions are compared with commercial Emerox biopolyols for rPUFs production. The different foams exhibit similar physical properties, but fire reaction, thermal stability, and compressive strength are improved using lignin-derived polyols, although only under specific liquefaction conditions.
