Interfacial bonding was enhanced by a coupling agent, such as maleic anhydride grafted polypropylene (MAPP). These hybrid composites were prepared using the twin-screw extrusion and injection molding process. Extensive tests were conducted to study the effects of reinforcement and MAPP on tensile strength, flexural strength, tensile modulus, flexural modulus, and dynamic mechanical properties. The obtained results showed a large improvement in mechanical properties: tensile strength improved up to 57.68% (from 35.82 to 56.48 MPa), flexural strength improved up to 52.59% (from 58.08 to 88.65 MPa), the value of tensile modulus improved up to 147% (from 2.00 to 4.94 GPa), and flexural modulus improved up to 86.04% from 2.65 to 4.93 GPa—in comparison to a plain 25% SWF/PP composite. DMA represented that the storage modulus increased by 129% from 2159.69 to 4938.20 MPa, while tan delta values reduced by 15%, signifying enhanced stiffness in concert with a reduction in molecular mobility. Thermal analysis exhibited enhanced thermal stability as char residue was increased from 1.82 to 16.81% at 700 °C in the optimum composites containing RHP and MAPP. These morphological and structural characteristics were characterized by using techniques from FTIR and 3D-OM to SEM–EDS; indeed, the enhanced interfacial bonding and homogeneous distribution of reinforcement were verified with MAPP assistance. The findings of this study demonstrate the potential of these green composites for high-performance applications in the automotive and construction industries.</p></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":"8 2","pages":""},"PeriodicalIF":23.2,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42114-025-01277-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polymer-derived ceramics (PDCs) offer a promising alternative, enabling the fabrication of complex shapes that traditional ceramics struggle to achieve. This study introduces a cost-effective method for producing robust PDCs using low-cost liquid crystal display (LCD) 3D printing combined with strategic nanofiller integration. By incorporating nanofillers such as silicon nitride and alumina into a silicon oxycarbide precursor (SPR-684) matrix, we significantly enhanced the mechanical properties of the resultant ceramics. Optimized formulations, including a photoinitiator for vat photopolymerization, were 3D printed into complex geometries, such as gyroids and lattices, and subsequently converted to ceramics through pyrolysis. We systematically investigated the effects of varying nanofiller concentrations (0.2 to 1 wt%) on the density, microstructure, and mechanical performance of the PDC lattices. The results showed remarkable improvements, with increases of up to 2060% in toughness, 20% in stiffness, and 900% in compressive strength attributed to nanofiller integration. In terms of biocompatibility, cytotoxicity assays revealed high cell viability and proliferation on the fabricated PDC scaffolds, indicating minimal cytotoxicity and supporting cell adhesion—key attributes for tissue integration in biomedical applications. Moreover, the compressive properties of the nanofiller-enhanced ceramics closely matched those of human trabecular bone, underscoring their suitability as load-bearing bio-implants. This LCD 3D printing method offers versatility, precision, and cost-effectiveness for bioceramic fabrication, positioning these materials as promising candidates for future biomedical devices where both mechanical performance and biocompatibility are critical.\u0000</p></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":"8 2","pages":""},"PeriodicalIF":23.2,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42114-025-01299-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PVDF was chosen for its strong electroactive polar phase and inherent tribo-negative properties. Cobalt ferrite (CF) NPs exhibit exceptional charge-trapping capabilities, while nickel’s metallic nature minimizes triboelectric losses due to its conductivity. The synergistic effects of Ni-doped CF (N-CF) fillers enhance charge-trapping efficiency and reduce triboelectric losses, significantly boosting TENG performance. Nickel oxide (NiO), CF, and N-CF NPs were synthesized using a facile co-precipitation method, and PVDF composites were fabricated through electrospinning. The physical and crystalline properties of the composites were characterized using various spectroscopic techniques. Results indicated that incorporating 3 wt% N-CF into PVDF optimized the <i>β</i>-crystalline phase content, crucial for improved output performance. Electrospun PVDF/N-CF (PNC) nanocomposite mats served as the tribo-negative (TN) layer, while aluminum (Al) electrode acted as the tribo-positive (TP) layer in TENG device fabrication. Electrical measurements showed that pristine PVDF/Al TENG devices exhibited lower performance (open-circuit potential—<i>V</i>_oc = 22 V, short-circuit current—<i>I</i>_sc = 0.61 µA) compared to the optimized Al/PNC3 TENG devices (<i>V</i>_oc = 421 V, <i>I</i>_sc = 1.0 µA). The importance of a spacer gap was emphasized, with devices incorporating a spacer gap demonstrating superior performance. The optimized TENG device successfully powered over 30 light-emitting diodes and a stopwatch in real-time applications.

The formation of an amide bond between Tri and rGO enables structural stability and enriches additional adsorption sites around Tri.

The main challenges in ZIBs are the formation of zinc dendrites and the hydrogen evolution reaction (HER), which can lead to short circuits and reduced battery life. To address these issues, the authors have functionalized chitin separators through a process involving alkaline treatment and mechanical grinding, resulting in nano-chitin fibers with varying degrees of deacetylation (D-x-ChNF). The D-4-ChNF separator, in particular, has been shown to have uniformly distributed nanochannels, high mechanical strength, and excellent electrochemical stability. It also exhibits a strong affinity for aqueous ZnSO₄ electrolytes and enhances the electrochemical reversibility of zinc through increased coordination with Zn²⁺ ions. This leads to a significant improvement in the battery’s cycle life, with the D-4-ChNF separator outperforming traditional glass fiber (GF) separators by more than six times in cycle life at 5 mA cm⁻² and 5 mAh cm⁻². The D-4-ChNF separator also demonstrates superior rate performance and long-term cycling stability, with capacity retention rates of 90.46% and 96.68% after 1000 cycles at 5 A g⁻¹ and 10 A g⁻¹, respectively. The separator’s ability to suppress dendrite growth and improve the uniformity of zinc deposition is attributed to its ability to reduce nucleation overpotential and promote uniform zinc deposition along the (002) crystal plane.
