In this context, the thermosensitive poloxamer Pluronic Acid F-127 (PF-127) is modified by incorporating polysaccharides with varying structures—xanthan gum (XG), alginate (ALG), gellan gum (GG), and levan (LEV). Hydrogels are synthesized using different ratios of polysaccharides and PF-127. Rheological results reveal that adding polysaccharides to the hydrogel matrix increases storage moduli from 8 to 11–18 kPa and viscosity from 4.5 to 6.1–7.1 Pa s. Additionally, the micellar aggregation capacity (MAC) and gelation temperature shift from 34 °C to between 22 and 31 °C. Studies on 5-fluorouracil (5-FU) release from these composites indicate that enhanced MAC prolongs drug release 4 times longer compared to the hydrogel made with PF-127 alone. A mathematical model is applied to analyze these experimental results, taking into account polymer chain release. Hydrogel's degradation rate and viscosity are primary determinants of drug release duration. Thus, by modifying the hydrogel composition, MAC, thermosensitivity, and drug release profile can be finely controlled based on the polysaccharide used.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 7","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400457","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144647066","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}

This study develops biodegradable composites based on poly (butylene adipate-co-terephthalate) (PBAT) and silane-treated wollastonite (S-W) at two concentrations (15 and 25 wt%) through a combination of melt extrusion and blow-film extrusion techniques. Next, the PBAT/S-W composite films underwent uniaxial stretching in the machine direction (MD) to study the effects on their morphology, mechanical and thermal properties, barrier performance, contact angle, and X-ray diffraction (XRD) at different stretch ratios (SR). The incorporation of S-W at 15 wt% increased the mechanical properties, achieving ≈500% for tensile strength and 1000% for Young's modulus for SR6. Thermal and XRD analyses demonstrated that uniaxial stretching significantly enhanced film crystallinity because of strain-induced crystallization. Morphological analysis indicated two opposing effects at high SR: a pronounced alignment of molecular chains in the MD and weak adhesion between the filler and polymer matrix, which can impact the material's structural integrity. The water vapor barrier properties of the PBAT/S-W25% blown film at SR6 exhibited a remarkable 42% improvement compared to the unstretched version. This advancement, resulting from the elevated crystallinity, establishes PBAT/S-W as a viable eco-friendly substitute for single-use plastics in the field of biodegradable packaging.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 7","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400434","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144646869","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}

Herein, gel nanocomposites (gel NCs) with photochromic properties are designed for light-induced 3D printing. The photochromic resin is prepared by using a photocurable acrylic formulation, containing tungsten oxide nanoparticles (WO3 NPs) in the presence of aqueous and alcohol plasticizers. After photopolymerization, gel NCs transition reversibly from a highly transparent colorless state to a dark blue-colored state when exposed to UV light. The addition of ethylene glycol to water as a co-plasticizer and a lithium salt improves the gels coloration kinetics while providing anti-freezing and anti-drying capabilities. The gels demonstrate high luminous transmission (Tlum) of 89.24% and optical modulations (ΔTsol) of up to 75.96%, with a coloration speed of less than 1 min. Energy-saving simulations show that the WO3 gel NCs can be used for heat management applications. The preparation of costume-made 3D designs using the photocurable resin with a digital light processing (DLP) 3D printer, demonstrates that the resin can be used for the additive manufacturing of photochromic gels.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 7","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400449","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144647052","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}

This study presents a novel hydrogel-embedded nanocomposite responsive to Near-Infrared (NIR) light (CN-Pt-DOX@CS+NIR) to induce necroptosis in lung cancer cells. The composite, created by combining Carbon Nanodots (CNs), Platinum Nanoparticles (PtNPs), and Doxorubicin (DOX) within a Chitosan (CS)-based hydrogel, demonstrated favorable properties for sustained drug release. Upon NIR irradiation, the CNs increase oxidative stress and initiate apoptosis due to the generation of reactive oxygen species (ROS) and caspase activation (3, 8, and 9). The PtNPs enhance ROS production and disrupt mitochondrial membrane potential (MMP), further promoting cell death. DOX, a well-known chemotherapeutic, intercalates DNA and inhibits topoisomerase II, leading to apoptosis. These combined effects result in significant cytotoxicity under NIR stimulation, as shown in vitro on A549 and H1299 cells, confirmed through various assays including AO/EB and DAPI staining, flow cytometry, and RT-PCR. Additionally, the hydrogel matrix provides a controlled release of the therapeutic agents and improves localized delivery. Combining CNs, PtNPs, and DOX with NIR enhanced in vitro cytotoxic effects, apoptosis, ROS generation, and potential for targeted lung cancer therapy.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 7","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400442","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144647766","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}
