However, the hydrophobic property and non-selective apoptosis still limit its application. Recently, drug delivery systems (DDS) such as polymer micelles, liposomes, and dendrimers have been widely developed to improve the efficiency of chemotherapy. In this work, the amphiphilic polymer was used to encapsulate the Doxorubicin (DOX) through the self-assembly process to form the polymer micelles, and the drug release of DOX was controlled by the temperature-sensitive monomer (triethylene glycol methyl ether methacrylate, TEGMA) and redox-responsive group (disulfide bond, S–S). On the other hand, the intracellular internalization was improved by the photosensitizer drug (protoporphyrin IX, PpIX) through the photochemical internalization (PCI) process. The lower critical solution temperature (LCST) of micelles in this work was 37.6 °C, and the in-vitro test showed that 96% of DOX was released under acid conditions with the high level of redox agent.

Effective wastewater treatment is crucial to mitigate these impacts. This study addresses the issue by developing a sustainable and cost-effective semi-interpenetrating polymer network (IPN) xerogel composite incorporating eggshell, hydroxyapatite (HAp), and chitosan for efficient dye removal. Ultrasonic-activated eggshell powder (UAESP), HAp, or their combination was integrated with chitosan-containing poly(methacrylic acid) (PMAA)-based xerogels to enhance adsorption capacities. Characterization using FTIR, SEM, EDS, XRF, BET, and tensile strength testing confirmed significant structural, textural, and mechanical enhancements. Adsorption experiments demonstrated high efficiency in removing dyes such as methylene blue, Congo red, crystal violet, and methyl orange, with the chitosan/UAESP + HAp composite achieving the highest adsorption capacity (98.4 mg/g) for Congo red. Kinetic studies revealed that adsorption follows a pseudo-second-order model, with chemisorption as the dominant mechanism. Furthermore, intraparticle diffusion analysis indicated that the adsorption process involved multiple stages, including boundary layer diffusion followed by intraparticle diffusion. Simulated textile wastewater tests confirmed the practical applicability of the xerogels, maintaining high dye removal capacities over multiple cycles. In conclusion, this study offers a sustainable and versatile solution for wastewater treatment, contributing to cleaner water resources and environmental sustainability.</p></div>","PeriodicalId":658,"journal":{"name":"Journal of Polymer Research","volume":"32 4","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143707110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The composites were fabricated using compression moulding and characterised for their mechanical, thermal, acoustic, and water absorption properties. The results showed that the incorporation of PNS biochar significantly enhanced its tensile strength of 47.36 MPa, flexural strength of 82.88 MPa, impact strength of 28.68 kJ/m<sup>2</sup>, and Shore-D hardness of 82.49, with an optimal concentration of 15 wt. %.

The sound absorption properties were also improved, with a maximum noise reduction coefficient (NRC) of 0.30. However, at high biochar concentrations (&gt; 15 wt. %), it led to particle clustering and void formation, resulting in reduced mechanical and acoustic properties. Scanning electron microscopy (SEM) revealed that these biochar composites had minimal void formation and strong interfacial bonding between the biochar and hemp fibres for the optimal 15 wt. % compositions.
