The main aim of this research was to electrospin lignin hydrogel in the form of nanofibers by engineering the polymer structure to form stimuli-responsive lignin nanofibers in alkaline pH. For this purpose, a blend of lignin/PVA (polyvinyl alcohol) and citric acid as a friendly cross-linker were electrospun. SEM images showed the best morphology of nanofibers at lignin/PVA of 98:2 with mean diameters of 215 and 176 nm on the static and rotational drum, respectively. The FTIR spectra and X-ray diffraction confirmed the formation of networks between the PVA and lignin chains. The produced nanofibers of lignin can classify as a smart nanohydrogel due to the high swelling ratio in alkaline pH. Antibacterial assays confirmed suitable activities against <i>S. aureus</i> and the fungus <i>Candida albicans</i> for the nanofibers with 20% lignin. Further, the cell cytotoxicity against cell fibroblast of the human skin showed reasonable cell viability. Finally, the nanofibers with 20% lignin collected on the rotational drum indicated the higher strength and modulus of elasticity. In conclusion, the fabricated stimuli-responsive hydrogel with 20% lignin showed suitable performance in antibacterial activity, cytotoxicity and it displayed good mechanical properties. In addition, due to the repulsive interactions between ionized carboxylic groups under alkaline pH, the swelling occurs. As a result, these nanofibers are potentially applicable in biomedical applications such as wound dressing.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":601,"journal":{"name":"Iranian Polymer Journal","volume":"34 5","pages":"751 - 764"},"PeriodicalIF":2.4,"publicationDate":"2024-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143821747","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}

By varying POE concentrations (ranging from 10 to 50%), this work comprehensively investigates their effects on printability, stability, adhesion, flexibility, and mechanical performance. The results indicated that higher POE content led to a notable decrease in stiffness, accompanied by improved damping properties and enhanced toughness. Specifically, tensile strength exhibited a reduction of 22% and 31% with each increment in POE content, while compressive strength decreased from 8.27 MPa to 4.56 MPa. Scanning electron microscopy (SEM) analysis underscored the enhanced filament bonding observed with higher POE content. The results of morphology investigation showed that at 10% POE content, well-distributed spherical domains showed excellent elastomer dispersion in the PP matrix, implying potential matrix droplet structure and surface adhesion between phases. By increasing the POE content to 50%, a sea-island structure with a continuous PP matrix and scattered POE domains appeared, which justified the results of increased elasticity and damping factor.

Data on copolymerization ability of these catalysts, molecular weight characteristics, and compositional homogeneity of the produced copolymers were attained. It was found that the introduction of 1-hexene led to broadening of the molecular weight distribution of copolymer (an increase in the <i>M</i><sub><i>w</i></sub>/<i>M</i><sub><i>n</i></sub> value) relative to homopolyethylene due to a decrease in the molecular weight (<i>M</i><sub><i>n</i></sub>) in the region of 1–100 kg mol<sup>−1</sup> without changes in the molecular weight in the region of <i>M</i><sub><i>n</i></sub> > 500 kg mol<sup>−1</sup> for two used VMCs catalysts. This result testified to non-uniformity of the active centers of these catalysts in the chain transfer reaction with participation of 1-hexene. Therefore, the active centers of VMCs producing high-molecular polyethylene were virtually not involved in the chain transfer reaction with 1-hexene. At the same time, these centers were more reactive in the incorporation of 1-hexene. This led to unusual distribution of butyl branches in ethylene–1-hexene copolymers produced over VMCs, namely, to an increased content of butyl branches in the high-molecular fraction of copolymers (<i>M</i><sub><i>w</i></sub> > 1000 kg mol<sup>−1</sup>).</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":601,"journal":{"name":"Iranian Polymer Journal","volume":"34 5","pages":"625 - 635"},"PeriodicalIF":2.4,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143821725","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}
