For the hydrothermal growth of TiO₂ nanowires, carbon cloth (CC) is used as a flexible, conductive base. The nanowires are then coated with polyaniline (PANI) through electrodeposition. This design takes advantage of the carbon substrate’s high conductivity and the structural flexibility of TiO₂ nanowires. The PANI coating provides important active sites for ion storage and reduces changes in volume during lithiation and delithiation. An analysis of the electrode’s electrochemical performance shows that it has a specific capacity of 297.7 mAh g⁻¹ after 100 cycles at a current density of 100 mA g⁻¹. This is a lot more than the 30.8 mAh g⁻¹ of TiO₂@CC alone, and the electrode has an initial Coulombic efficiency of 85.2%. Electrochemical impedance spectroscopy indicates superior lithium-ion diffusivity in the TiO₂@CC@PANI structure. Rate performance tests confirm the high structural stability of the TiO₂@CC@PANI electrode under various charge/discharge conditions. These findings demonstrate the enhanced capacity and structural integrity of lithium-ion batteries utilizing TiO₂@CC@PANI anodes, underscoring their potential for high current–density applications.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"59 44","pages":"20657 - 20670"},"PeriodicalIF":3.5,"publicationDate":"2024-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142691903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nowadays, PLA is the most industrially used compostable polymer, but its uses are limited by its low crystallization and thermal degradation during processing. The possibility of introducing functionalized silsesquioxanes (SQs) to improve thermal stability and increase its crystallinity and ductility in a controlled way is desirable. The nanometric size of the Si-O-Si cage, coupled with the influence of the functional groups attached to its structure, enables it to function as a heterogeneous nucleating agent. In this work, a specially synthesized octa-phenyl-substituted SQ (phSQ) was added to the PLA in 0.5–5 wt%. Crystallization in non-isothermal and isothermal conditions was conducted and monitored using differential scanning calorimetry (DSC); the course of the spherulite formation under identical conditions to DSC was also assessed using optical microscopy in polarized light. The results showed that phSQ increases the degree of crystallinity of PLA by introducing additional sites of heterogeneous nucleation but does not increase the spherulite growth coefficient. Additionally, the analysis of thermal properties indicates that the presence of phSQ could not have a positive impact on thermal stability. The agglomeration of the nanometric particles and changes in the main structural features of the polymeric matrix could be present in the samples, affecting the obtained results.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"59 43","pages":"20445 - 20461"},"PeriodicalIF":3.5,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10853-024-10328-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142645619","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}

Disentanglement is an effective method to improve the processing performance of polymers without sacrificing mechanical properties. Although there are some methods to reduce the entanglement degree of polymers, few methods can preserve the disentangled state in pellets for secondary processing. Long-chain branched polypropylene (LCB-PP) has a slower entanglement recovery rate due to its branched chain. Thus, it is worth studying whether the disentangled state of LCB-PP can be kept in pellets to improve processing performance during secondary processing. In this work, disentangled LCB-PP was successfully prepared using the self-designed polymer melt disentanglement device that can apply a complex shear field (a superposition of rotational shear and oscillatory shear) to polymers. The effect of the rotational shear, oscillatory shear, and complex shear on disentanglement was studied. The results show that the complex shear field has a better effect on the disentanglement of LCB-PP, which is endowed with lower viscosity and higher melt flow rate compared to rotational shear and oscillatory shear. In secondary processing, the processing temperature and injection pressure required for disentangled LCB-PP are significantly reduced while mechanical properties are maintained.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"59 43","pages":"20462 - 20479"},"PeriodicalIF":3.5,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142645617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prepregs were thermally treated at various temperatures, the physical and mechanical performance evolution of the prepregs at different carbonization stages were analyzed. Comparative study of the features of the prepregs with pyrocarbon coated and uncoated carbon fiber as a reinforcement were carried out.
