Herein, a fully biobased cardanol-grafting dimer acid diglycidyl ester (CGDAE) coating for paper substance was fabricated through the ethoxylation of dimer acid (DA) and then addition with cardanol under solvent-free conditions. The results indicated that the packaging performance of the paper substance was significantly improved after coating with the mixture of resulting CGDAE and oxidized starch (OS); among them, the paper covered with 80 wt % of CGDAE and 20 wt % OS (80% CGDAE/OS-p) exhibited excellent water resistance (water contact angle of 110.3°) and oil repellency (kit rating 11/12), which were increased 2.9 and 3.7 times compared with those of paper substance coated by traditional OS (OS-P). Compared with those of paper coated by OS (OS-p), benefiting from the formation of dense coating and the hydrophobic long-chain alkyl groups, the water vapor transmission rate and oxygen permeability of 80%CGDAE/OS-p decreased by 57.8% and 96.5%, respectively, and the freshness lifetime of strawberries packaged with coated paper was increased from 4 days (OS-p) to 7 days (80%CGDAE/OS-p). The pulp repulpability of 80%CGDAE/OS-p was confirmed by washing and a repulping treatment. This study presents a cost-efficient and industrial strategy for fabricating fully biobased, recyclable, and water- and oil-resistant coatings for paper-derived packaging.","PeriodicalId":7,"journal":{"name":"ACS Applied Polymer Materials","volume":"7 10","pages":"5834–5845 5834–5845"},"PeriodicalIF":4.4,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144114778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a series of nonconjugated polyurethane derivatives (PUs) with full-color emission are easily obtained through facile one-pot reactions.

The electronic structure of the PUs was investigated by using density functional theory. The results suggest that the final aggregate structure of the material and the interactions within the system rather than its inherent electronic structure play a decisive role in launching its emissive behavior. Detailed photophysical and microscopic morphology characterizations elucidate the intricate aggregated photophysical behavior of the PUs. Thanks to the long wavelength absorption and emission of PUT-H, low toxicity, and good biocompatibility properties, water-soluble PUT-H NPs have been successfully applied for the photothermal ablation of thrombosis in vitro.

The pristine PSF membrane was fabricated by utilizing the immersion precipitation phase inversion technique. The presence of MXene in the TFNc membrane was confirmed using FESEM analysis.

Subsequently, the gas separation studies of the TFNc were conducted, and it was observed that 0.5 wt % of the MXene-embedded TFNc membrane showed the maximum CO2 permeance with a value of 23.822 GPU. It also displayed maximum CO2/N2 and CO2/CH4 selectivity since the MXene results in the creation of more tortuous pathways, as well as the hydroxyl group present on the MXene, which leads to the selective permeation of CO2 molecules.

These APs enabled the straightforward synthesis of PUs with very low surface polarity, low glass transition temperatures, excellent mechanical performance, and high hydrolytic stability. Importantly, the incorporation of cleavable acetal bonds allowed closed-loop recycling of the PUs under mild acidic conditions, enabling high-yield recovery of monomers. To demonstrate their versatility, the APs were used in two-component PU coatings, which exhibited strong adhesion to aluminum, superior hydrophobicity (contact angles >97°), and efficient debonding under environmentally benign conditions.

Cell phones, lamp lights, televisions, wind turbines, and other contemporary electronics rely heavily on rare earth elements. As a result, this work aimed to prepare eco-friendly dialdehyde chitosan with semicarbazide (SC/DiACs), a promising method for recovering lanthanum, cerium, and neodymium from phosphate leach solution. Different analytical techniques were utilized to determine the physicochemical properties of SC/DiACs before and after adsorption. Sorption was conducted at pH 5 for 60 min using 50 mg SC/DiACs and 200 mg/L La, Ce, and Nd ions. The sorption capacities were 193.52 mg/g for La, 186.77 mg/g for Ce, and 171.37 mg/g for Nd. The studied ions’ sorption onto the SC/DiACs sorbent was well-fitted by the pseudo-first-order (PFO) and the isotherm produced by Langmuir. Besides, it was discovered that the sorption thermodynamic characteristics were both spontaneous and exothermic. La, Ce, and Nd ions were successfully desorbed from the SC/DiACs by imperiling it to 0.7 M/L HNO3 and 35 min at 25 °C with a 1:40 solid/liquid (S/L) ratio. Also, the SC/DiACs sorbent was rejuvenated after seven cycles of sorption–desorption. SC/DiACs sorbent was exploited to recover RE ions from the phosphate leach solution. Ion purity levels of 90.18% were achieved by calcining the precipitate to RE oxides. Finally, the SC/DiACs sorbent was found to have excellent sorption characteristics for RE ions in their solution, as evaluated by the REEs recovery behaviors.","PeriodicalId":7,"journal":{"name":"ACS Applied Polymer Materials","volume":"7 10","pages":"6348–6364 6348–6364"},"PeriodicalIF":4.4,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144114578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was found that the exfoliation yield of graphite after three rounds of pretreatment increased by 2.2 times that of untreated graphite, achieving a yield of 31%. Moreover, the incorporation of CNC further improved the exfoliation yield by 4.6 times compared to that without CNC.
