Cellulose obtained from industrial licorice-root waste, an inexpensive raw material, was used as a renewable precursor in its microcrystalline (MCC) and nanocrystalline (NCC) forms. Methyltrimethoxysilane (MTMS) was employed as the silicon source as well as the hydrophobic modifying agent. During the study, the effects of the MCC and NCC/MTMS molar ratio, reaction temperature, and reaction time on composite formation were systematically investigated. The results showed that a molar ratio of MCC and NCC/MTMS of 1:1.8, a reaction temperature of 80–100 °C, and a reaction duration of 60 min represented the optimal conditions for composite formation. The composites synthesized under these optimized parameters exhibited pronounced hydrophobic properties. The water contact angles of pristine microcrystalline cellulose (MCC) and nanocrystalline cellulose (NCC) were determined to be 15° ± 1°, indicating their intrinsically hydrophilic nature. In contrast, after silica modification, the water contact angle increased significantly to 120° ± 1° for the MCC–(CH₃SiO₁.₅)ₙ composite and to 136° ± 1° for the NCC–(CH₃SiO₁.₅)ₙ composite, confirming the successful formation of hydrophobic surfaces. The structural and thermal properties were evaluated using X-ray diffraction (XRD), thermogravimetric analysis (TGA), and Fourier-transform infrared spectroscopy (FTIR). Additionally, the hydrophobicity and oil/grease adsorption efficiency were assessed. The resulting materials exhibited enhanced water repellency, high thermal stability, and superior adsorption capacity for oil and grease. The utilization of cellulose–silica composites as sustainable adsorbents for the remediation of hydrocarbon-based pollutants is a promising avenue for environmental restoration.</p></div>","PeriodicalId":658,"journal":{"name":"Journal of Polymer Research","volume":"33 8","pages":""},"PeriodicalIF":3.5,"publicationDate":"2026-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148750893","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}

The copolymerization constants values of these monomers (r₁ = 1.1; r₂ = 0.35) have been calculated and it has been revealed that in this case, 2-formyl-1-(p-vinylphenyl)cyclopropane is a more active monomer during radical copolymerization.

The composition, structure and photosensitive properties of the synthesized copolymer samples have been determined. It was established that the obtained copolymer has an alternating structure and the availability of highly absorbing ketone, cyclopropane, epoxide and ester groups in the macromolecules gives the copolymer a high photosensitive activity. The copolymer samples are inclined to be undergo photochemical transformations during radiation and the absorption boundary of the electron spectra of the copolymer samples is below 320 nm. For increasing the photosensitivity of the copolymer, a sensitizer was introduced and as a result, by means of a sensitizer, the absorption boundary was shifted to 360 nm.

Three PSPOs (synthesized from succinic, adipic, and dodecanedioic acid) were formulated with either ethylenediamine (EDA) or 1,4-butanediol (BDO), due to the fundamental differences in their chemical reactivity. The structure-property relationships of the adhesives, formulated with varying polyester polyols and chain extenders, were systematically investigated using analytical techniques including differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FT-IR), gel permeation chromatography (GPC), proton nuclear magnetic resonance (¹H NMR), melt viscometry, lap shear testing, and isocyanate titration. EDA-based adhesives have consistently demonstrated superior crosslinking efficiency, resulting in significantly enhanced mechanical performance and faster cure kinetics. The PSPO-1_EDA formulation exhibits a cure time of 8.5 h. In contrast, BDO formulations exhibited greater flexibility and lower processing viscosity. The longest-chain polyol, PSPO-3, was found to be the most high-performing, achieving the highest lap shear strength of 2.0 MPa when coupled with EDA, a result attributed to its ability to form highly ordered hard domains (ΔH_m = 31 mJ/mg).

Moreover, for the same initial cast sheet, the surface roughness of the film decreased with the increase in draw ratio. Fitting analysis revealed a significant linear negative correlation between the dielectric breakdown strength of the films and their surface roughness.

The chemical structures of the coumarin precursor, monomer and polymer were confirmed by FTIR, NMR, and mass spectrometry. Optical study revealed strong blue fluorescence from FRPP (<i>λex</i> = 386 nm) with an enhanced relative quantum yield (<i>Φ</i> = 0.81) of polymer, determined using 7HCPC as an internal reference and compared with the monomer (<i>Φ</i> = 0.19), which is consistent with reduced non-radiative relaxation within the polymer matrix. UV-visible Tauc analysis gave optical band-gap values of 3.25 eV for 7HCPC, 3.15 eV for FRP, and 3.61 eV for FRPP, showing that polymerization slightly modified the optical transition behaviour. X-ray diffraction analysis indicated a transition from the semicrystalline monomer to an amorphous polymer after polymerization. Thermal analysis revealed improved thermal transition of FRPP, including a glass transition temperature of 75.8 °C and delayed thermal degradation and increases char yield relative to FRP.

Herein, shape-stabilized PEG/epoxy resin (EP)/hexagonal boron nitride (hBN) composites were fabricated via a facile melt-blending and curing route, using EP as the supporting matrix and ball-milled hBN as the thermally conductive functional filler. First, the regulatory effect of PEG molecular weight (4000–20000) on the phase change behavior and anti-leakage performance of PEG/EP matrix (mass ratio 7:3) was systematically investigated, and the trade-off between energy storage density and shape stability under different molecular weights was clarified. The PEG6000/EP composite was identified as the optimal matrix, with a melting enthalpy of 159.78 ± 2.1 J·g^− 1 and a melting peak temperature of 62.56 °C. Subsequently, the influence of hBN content (10–50 wt%, relative to the total mass of PEG/EP blend) on the comprehensive properties of the composites was explored. Combined with differential scanning calorimetry (DSC), X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR), a plausible multi-scale regulation mechanism of hBN on phase change behavior, anti-leakage performance and thermal conductivity is tentatively proposed and discussed. Results show that hBN simultaneously improves the thermal conductivity and anti-leakage performance of the composites while maintaining acceptable phase change enthalpy, based on a hypothesized hierarchical mechanism involving potential intermolecular hydrogen bonding, crystal structure regulation, and inferred overlapping lamellar barrier pathways (tentatively regarded as a quasi-continuous three-dimensional functional network). At the optimal hBN loading of 40 wt% (relative to the PEG/EP blend, corresponding to 27.4 wt% in the final composite), the composite maintains a mass retention rate of 99.01% after 5 h thermal exposure at 65 °C, and its thermal conductivity is significantly enhanced, reaching 0.384 ± 0.015 W·m^− 1·K^− 1, along with a melting enthalpy of 55.58 ± 1.3 J·g^− 1. These properties make the composite suitable for medium-to-low-temperature thermal energy storage scenarios. XRD and FTIR characterizations indicate that hBN may serve as a heterogeneous nucleation agent and interacts with the matrix through physical interactions such as possible hydrogen bonding (FTIR spectral shifts provide indirect evidence), with no evidence of new chemical bond formation observed.
