SEM micrographs revealed a distinct microporous surface morphology in the composite film treated at 75 kGy, indicating significant structural modifications induced at this irradiation dose. AFM result showed that surface roughness was attained twice that of the pristine. Crystallinity and crystallite size were found to decrease with irradiation, and the predominant (110) peak of PHB was slightly shifted from 21.5 to 21.7° at 50 kGy. Water contact angle (WCA) measurements demonstrated increased hydrophilicity, with values rising from 83 to 89° up to 50 kGy. The composite film irradiated at 75 kGy exhibited the lowest hemolytic activity, higlighting its superior hemocompatibility than that of pristine and other irradiated samples. Cell viability assays revealed that fibroblast proliferation reached its maximum at 75 kGy, outperforming both the pristine and other irradiated composite films. These results highlight the ability of γ-irradiation to tune key properties of PHB composite films, including crystallinity, surface roughness, hydrophobicity, hemocompatiblity, and cell proliferation. By enhancing the morphological, structural, and biological performance, γ-irradiated PHB composites show great promise for tissue engineering applications.</p></div>","PeriodicalId":737,"journal":{"name":"Polymer Bulletin","volume":"82 15","pages":"10319 - 10340"},"PeriodicalIF":4.0,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145248343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, controlled synthesis of PVA via CMRP of vinyl acetate (VAc) can be a helpful technique to address the limitations related to the poor printability and rapid degradation rate of pure PVA for biomedical applications. In this research, PVAc was synthesized under controlled conditions using CMRP of VAc. The polymerization was performed with different initiator ratios at different temperatures using cobalt(II) acetylacetonate (Co(acac)₂) as the controlling agent and benzoyl peroxide (BPO) as the initiator. Also, N,N-dimethylformamide (DMF) was used as the ligand. The increase in the initiator ratio and temperature led to an accelerated polymerization process. For instance, the polymerization finished after 110 and 80 min for 0.75 and 1 initiator ratio, respectively. It is important to highlight that each experiment was repeated at three distinct time intervals after obtaining maximum viscosity of the polymerization system. The conversion rate of monomer to polymer and ln[M]₀/[M] ratio increased over time, demonstrating the controllability of the polymerization. The Co(acac)₂ complex successfully acted as the controlling agent in the polymerization process. Homopolymerization of VAc was then optimized, and optimum PVAc samples were successfully hydrolyzed to PVA homopolymers, which was confirmed by proton nuclear magnetic resonance (¹H NMR) analysis. PVA homopolymers were synthesized with controlled molecular weight (M_n), which was illustrated by gel permeation chromatography (GPC) test. Furthermore, the polymers showed suitable printability using fused deposition modeling (FDM) technique. According to the scanning electron microscopy (SEM) analysis, pore size in PVA scaffolds increased with an increase in M_n. The swelling ratio after 24 h decreased from 97.413% to 84.215% by increasing the M_n from 8840 to 12,266. Also, the degradation ratio after 28 days decreased from 85.113% to 74.118% for the same M_n. This phenomenon was attributed to the higher chain entanglements in higher M_n. Therefore, the swelling capacity and the degradation of the PVA scaffolds were successfully controlled by controlling the M_n. Hence, using CMRP method, pure PVA scaffolds can be obtained and widely used in biomedical applications such as tissue engineering and drug delivery as they are controllably degradable and biocompatible.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":737,"journal":{"name":"Polymer Bulletin","volume":"82 15","pages":"10279 - 10299"},"PeriodicalIF":4.0,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145248371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Fourier transform infrared spectroscopy, transmission electron microscopy, scanning electron microscopy, thermogravimetric analysis, and small-angle X-ray scattering were employed to characterize the composition and structure of the PLA/MBGs-LVFX/PVA unidirectional drug release system. Nitrogen absorption characterization confirmed that the specific surface area of MBGs reached 485.6 m²/g with an average pore diameter of 6 nm. The PLA/MBGs-LVFX/PVA polymer composite exhibited a levofloxacin hydrochloride (LVFX) loading capacity of 41.17%, an encapsulation efficiency of 66.5%, and a cumulative release rate reaching 61.28% within 24 h, demonstrating excellent drug loading and release capabilities. The mechanism by which PVA controlled the release of LVFX was discussed. The biodegradation of the drug release system in PBS led to a certain increase in pH, which is conducive to bactericidal efficacy. In vitro bioactivity assessment confirmed that this drug release system had no significant cytotoxicity at a reasonable dosage. This unidirectional drug release film is expected to achieve targeted drug delivery to focal sites rich in sensitive nerves, thereby improving drug efficacy and reducing side effects on the nervous system.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":737,"journal":{"name":"Polymer Bulletin","volume":"82 15","pages":"10301 - 10317"},"PeriodicalIF":4.0,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145248319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores the innovative use of polyacrylamide lactic acid modification (PAM-LA) as a water-soluble, pH-responsive glue to addresses the need through its enhanced adhesive properties and environmental safety. Polyacrylamide was modified with lactic acid to introduce carboxyl groups, significantly improving its adhesive capabilities via increased hydrogen bonding and electrostatic repulsion. Spectroscopic analyses (IR, ¹H NMR, ¹³C NMR) confirmed the successful incorporation of lactic acid into the polyacrylamide backbone. Viscosity measurements demonstrated unique behaviors, typical of polyelectrolytes, with a notable increase in viscosity upon dilution due to enhanced ionization of carboxyl groups. Potentiometric titration revealed that the amount of alkali required for titration was proportional to the modification time, indicating an increase in carboxyl groups. Key results show that the pH-responsive nature of PAM-LA allows for tunable adhesive properties, with higher pH levels leading to greater swelling and stronger adhesion. The rate constants for PAM-LA at different pH values were measured, with values such as 8.2 × 10⁻³ at pH 1.68, 10.5 × 10⁻³ at pH 6.85, and 15.5 × 10⁻³ at pH 9.15, indicating increased reactivity and adhesion with rising pH.
