Increasing UV exposure time consistently improved tensile strength and toughness by enhancing curing efficiency and interlayer adhesion, while reducing layer thickness minimized curing defects and further strengthened the printed structures. Thermogravimetric analysis confirmed thermal stability well above physiological temperatures, and contact angle measurements (42–59°) demonstrated tunable surface wettability.

FESEM analysis confirmed uniform, bead-free fibers with interconnected porosity, with PHB/PVA/BCP showing enhanced surface roughness and BCP particle distribution. EDS verified the successful incorporation of Ca (4.25%) and P (2.56%) within the composite. Furthermore, FTIR and XRD confirmed the presence of characteristic PHB and PVA functional groups and clear crystalline peaks of BCP, indicating strong polymer-filler interactions. Additionally, mechanical strength revealed that PVA exhibited the highest tensile strength (83.29 MPa) and elongation (64.76%), while PHB showed the highest stiffness (1017 MPa). The PHB/PVA/BCP scaffold demonstrated balanced mechanical properties (UTS 25.10 MPa; Young’s modulus 21.0 MPa), suitable for supporting early-stage bone regeneration. Sterility tests confirmed that PHB-containing scaffolds remained stable in culture media, while PVA dissolved rapidly. Although no scaffold exhibited antibacterial activity, biofilm analysis showed the lowest biofilm formation on PHB (P1) after 24 and 48 h. Water absorption studies showed maximum uptake in PVA (300%), moderate swelling in PHB/PVA (150%), and controlled absorption in PHB/PVA/BCP (125%). Degradation analysis revealed minimal mass loss in PHB (20% at 5 weeks), rapid dissolution of PVA, and accelerated but controlled degradation in PHB/PVA (55%) and PHB/PVA/BCP (50%).

The resulting liquefied products were characterised by hydroxyl number, acid number, liquefaction yield, residual content, Fourier transform infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). The bamboo-derived polyol exhibited a hydroxyl value of 297 mg KOH g⁻¹ and a liquefaction yield of 91.9%, whereas the Japanese cedar bark-derived polyol exhibited corresponding values of 283 mg KOH g⁻¹ and 91.3%. Both biomass feedstocks produced bio-polyols with comparable liquefaction yields. FT-IR confirmed the characteristic functional groups of the liquefied bio-polyols and the corresponding polyurethane adhesives, while TGA and DSC revealed differences in their thermal response during heating. The liquefied bio-polyols were subsequently used to prepare polyurethane (PU) adhesives containing different proportions of biomass-derived polyol. Tensile strength and failure mode were evaluated under different curing conditions. Bamboo-based adhesives exhibited relatively consistent tensile strength across the investigated formulations, whereas bark-based adhesives showed higher mean tensile strength for some formulations, although variation among replicate measurements was observed. Both adhesive systems predominantly exhibited cohesive failure.

In this context, Polyvinyl Alcohol (PVA) composite films reinforced with bio-derived Silicified Microcrystalline Cellulose (SMCC) and Zinc Oxide (ZnO) nanoparticles were fabricated to develop biodegradable multifunctional films with enhanced properties. Bare PVA, PVA/MCC and PVA/SMCC films were also fabricated to assess the individual and synergistic effect of Microcrystalline Cellulose, SMCC and ZnO nanoparticles on the overall performances of films. On analysis, PVA/SMCC showed reduced water uptake and water vapour transmission compared to PVA/MCC while PVA/SMCC-ZnO exhibited the lowest moisture absorption by restricting polymer chain mobility. Antibacterial studies revealed no activity for PVA, PVA/MCC and PVA/SMCC, while PVA/SMCC-ZnO film exhibited a distinct inhibition zone of ~ 11 mm against both E. coli and S. aureus, which is attributed to ZnO induced reactive oxygen species generation and membrane disruption. Soil burial studies demonstrated that MCC enhances the biodegradability of PVA, while SMCC and ZnO suppresses the biodegradation due to their antimicrobial nature. FE-SEM analysis supported these findings, revealing severe surface deterioration in PVA/MCC films, moderate degradation in PVA/SMCC, and minimal morphological changes in PVA/SMCC–ZnO films. Contact angle increased from 67.3° (PVA/MCC) to 86° (PVA/SMCC) and 92° (PVA/SMCC–ZnO), indicating enhanced hydrophobicity. Mechanical testing indicated that PVA/SMCC–ZnO possessed superior tensile strength with reduced elongation at break.

This paper proposes a green and low-cost modification strategy by investigating the effect of waste biomass, tomato peel residue (TP), on the crystallization performance and melting behavior of PLA. The results demonstrate that TP with an average particle size of 4.56 μm after ultrafine grinding can significantly promote the crystallization process of PLA. Under isothermal crystallization conditions at 96 °C, the addition of 5 wt% TP notably reduced the half-crystallization time of PLA from 10.05 min to 1.55 min, corresponding to an approximately 6.5-fold increase in the crystallization rate. Under non-isothermal conditions at a cooling rate of 5 °C/min, the degree of crystallinity was enhanced by 6.8-fold. These improvements are substantially superior to the effects achieved by single-component lignin or cellulose under identical conditions. Further analysis via crystallization kinetics and surface free energy characterization indicates that TP primarily facilitates PLA crystallization by providing abundant heterogeneous nucleation sites and strengthening interfacial interactions. The multi-component composite system of TP exhibits a distinct synergistic enhancement effect.

However, the inherent limitations of this method require subsequent heat treatment to eliminate residual monomers. In this work, a previously unconsidered thermally initiated polymerization of acrylates with Irgacure 784 was investigated. Polymerization was studied in an isoconversion mode with varying heating rates, the content of molecular oxygen in the reactor atmosphere, as well as with different contents of functional carbon particles - astralenes. The kinetic parameters of the process were determined using the Friedman method. It has been established that polymerization occurs at temperatures above 150 °C and is accompanied by destruction of the monomer. The effective activation energy of thermally initiated polymerization is 90–115 kJ/mol and is comparable to the energy of radical polymerization of acrylate esters. The addition of astralenes slightly inhibits polymerization kinetics but improves the properties of the material in concentrations up to 0.05%. In a nitrogen atmosphere, increasing the heating rate reduces the loss of monomers, increases the proportion of linear polymers and lowers the glass transition temperature. Molecular oxygen completely inhibits polymerization, and the process can only occur in the presence of astralenes. However, polymerization is accompanied by pronounced thermal-oxidative destruction. In general, the properties of thermally produced polymers differ from the properties of photopolymers of the same composition. The results contribute to a better understanding of post-processing in such systems and suggest a potential alternative route to photopolymerization.</p></div>","PeriodicalId":658,"journal":{"name":"Journal of Polymer Research","volume":"33 8","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148782152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
