Natural biomaterials like alginate and gelatin have been widely studied to formulate bioinks due to their excellent biocompatibility and biodegradable characteristics. However, the requirement for balanced features combining adjustable degradation rate, printability, and biological functionality is still hard to achieve. In this study, alginate dialdehyde (ADA) – gelatin (GEL) based hydrogels have been supplemented with mesoporous bioactive glass nanoparticles (MBGNs) and human platelet lysate (HPL) to enhance the biological performance. MBGNs can reduce the degradation of ADA-GEL 3D printed scaffolds and induce a mineralization effect while HPL is added as a source of growth factors. Improved printability and higher shape fidelity are observed by incorporating 0.1% (w/v) MBGNs, however, the addition of HPL led to a slight decrease in 3D printed shape fidelity. On the other hand, MBGNs and HPL both presented positive effects to improve cell activity and viability, which is characterized by using MC3T3-E1 pre-osteoblast cells. The ADA-GEL-based hydrogel with the incorporation of 0.1% (w/v) MBGNs and 5% (v/v) HPL shows the most balanced features, making it a promising biomaterial for 3D bioprinting of bone tissue scaffolds.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 9","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202500121","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145062868","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}

Given the complex, nonlinear interactions among tribological parameters such as contact pressure, sliding speed, hardness, and filler composition, traditional empirical models often fail to capture wear behavior accurately. The proposed ANN architecture comprises an input layer, three hidden layers employing sigmoid, ReLU, and power activation functions, and an output layer predicting COF and SWR. The network is trained using a feed-forward method with backpropagation to minimize prediction error. SEM analysis reveals that graphite imparts superior wear resistance compared to MoS₂. The ANN achieved significantly higher prediction accuracy for graphite-reinforced composites. For COF, graphite yielded an MSE of 0.00073 and R² of 0.9047, while MoS₂ showed an MSE of 0.00318 and R² of 0.5567. For SWR, graphite attained an MSE of 1.3351 and R² of 0.9809, compared to MoS₂ with an MSE of 1.6993 and R² of 0.8271. The reduced performance in MoS₂ predictions is attributed to its oxidative degradation forming MoO₃.

FTIR analysis confirms that incorporating bCNTs into PVDF significantly enhances the β-phase content, while adding ZnO NWs (1–10 wt.%) resulted in progressive intensification of β-phase characteristic peaks, with higher ZnO content showing stronger electroactive phase formation. The optimized composition (PVDF/0.5 wt.% bCNTs/5 wt.% ZnO NWs) demonstrates superior piezoelectric performance with a power density of 5.62 µW cm−2, voltage output of 1.55 V, and current output of 14.48 µA. Moreover, the composite exhibits excellent mechanical properties with a tensile strength of 48 MPa and maintains stable performance under cyclic loading.

This study investigates the multifunctional properties of polyamide 6/polyamide 12 (PA6/PA12) (75/25) CPCs filled with multi-walled carbon nanotubes (MWCNTs). The present research focuses on the morphological, rheological, thermal, and electrical properties of nanocomposites. The incorporation of MWCNTs into the PA6/PA12 blend is achieved using twin-screw extrusion, and compression molding is used to obtain nanocomposites. Different MWCNT loadings are examined to optimize the dispersion and connectivity of the conductive filler network. Morphological analysis via scanning electron microscopy reveals significant structural changes with increasing MWCNT content, changing from a sea-island morphology to a more interconnected network. Differential scanning calorimetry provides insights into the thermal behavior, showing changes in melting and crystallization behavior as well as crystallinity degree with filler loading. Rheological assessments demonstrated variations in complex viscosity, storage modulus, and loss modulus with different MWCNT contents.

The study optimizes wear mechanisms and friction-induced graphitization by incorporating pristine (P-MWCNTs), carboxyl-functionalized (COOH-MWCNTs), amine-functionalized (NH₂-MWCNTs), and silane-modified MWCNTs. Composites were characterized for tensile strength, compressive strength, surface hardness, coefficient of friction (COF), and specific wear rate (SWR). Incorporation of 0.3 wt.% COOH-MWCNTs yielded optimal performance, reducing SWR by 82% (0.07 × 10⁻⁶ mm³ N⁻¹·m⁻¹ at 8 Hz) and COF by 32% (0.37 at 10 N) relative to neat epoxy (SWR: 0.50 × 10⁻⁶ mm³ N⁻¹·m⁻¹, COF: 0.66 at 15 N). Enhanced dispersion, interfacial adhesion, and tribofilm formation account for superior tensile strength (≈90 MPa) and hardness (≈88 Shore D). X-ray diffraction and transmission electron microscopy validated friction-induced graphitization and partial structural degradation above 10 N. Applications encompass self-lubricating bushings, protective coatings, and wear-resistant surfaces for automotive and industrial components.

In this work, three AB2-type monomers with 0-2 methoxy groups are synthesized using three corresponding lignin-based monomeric aromatics and a potentially biobased hydandoin. The obtained AB2-type monomers are conveniently polymerized via conventional bulk polycondensation to yield three UV-active hyperbranched polyesters. The molecular and thermal characteristics of the obtained hyperbranched polyesters are characterized by nuclear magnetic resonance (NMR), Fourier transform infrared spectroscopy (FTIR), high resolution mass spectrometry (HRMS), gel permeation chromatography (GPC), thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC). The monomers with 0 and 2 methoxy groups and their corresponding polymers provide protection in the UV B region, while the monomer with 1 methoxy group and its corresponding polymer provide protection in both UV A and UV B regions. All the obtained polymers exhibited strong UV absorption with molar extinction coefficient (ε) of ≈15600 to 21000 L mol−1 cm−1. The obtained polymers can be conveniently blended into creams, which exhibited desirable photostability after 4 h of exposure to direct sun light. Finally, these hyperbranched polyesters showed negligible leakage into fresh or salt water during 76 h from their blended creams, which indicated their potentially low environmental impacts as new UV blockers for sunscreens.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 9","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202500085","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145062825","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}

Thanks to the synergistic effect of active environmental responsiveness and electrical conductivity, SRCHs show a broad application prospect in smart sensing and actuation. However, due to the complexity of the environment, it is still difficult to utilize SRCHs materials to construct sophisticated smart devices. This paper systematically reviews the progress of SRCHs in material design and smart sensing and actuation applications in the past five years, focuses on their stimuli-responsive mechanisms and performance optimization strategies, and summarizes the current challenges and future development directions, with a view to providing theoretical references and technological inspirations for the development of next-generation smart materials.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 9","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202500097","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145062826","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}

However, the common fibrous heat preservation materials always suffer from heavy weight, poor mechanical properties, inadequate thermal insulation performance, and a lack of antibacterial properties. In this study, a facile approach for fabricating washable and antibacterial polystyrene (PS)/polyurethane (PU) fibrous sponges by direct electrospinning is demonstrated. The ultrafine fibers with rough structures are created due to the different phase separation rate of two polymers in the jet, which endows the sponge with hydrophobic property. Meanwhile, stiff PS and soft PU can synergistically improve the mechanical properties of the sponge (nearly without deformation after 1000 stretching and compression), which further endows washable property to the sponge. Moreover, the antibacterial performance is obtained through the incorporation of antibacterial agents, demonstrating a high antibacterial rate of 98.9% even after 10 washing cycles. In addition, the fibrous sponge also shows ultralight property (3.89 mg cm−3) and desired warmth retention performance with thermal conductivity of 23.77 mW m−1 K−1.
