Acrylic resin/micro-SiO 2 /polymethyl urea (AC/SiO 2 /PMU) composites were prepared by physical blends of acrylic resin latex (AC), polymethyl urea resin (PMU), and modified SiO 2 . The effects of SiO 2 and PMU content in the hybrid composites morphology and physical properties were investigated in detail using transmission electron microscopy (TEM), UV-Vis spectrometry (UV-Vis), scanning electron microscope (SEM), thermogravimetric analysis (TGA), and contact angle measurement. The results showed that introduction of SiO 2 into AC composites could increase the viscosity which caused by gelation and agglomeration of SiO 2 . The TEM, SEM images, and TGA results indicated that hybrid membranes have phase separation. During the film formation process, a high number of PMU and SiO 2 particles of an appropriate size were stranded on the surface of the film to form matting surface. These results highlight the sensitivity of the gloss to the polymer morphology and surface. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015 , 132 , 41707.

A series of thermoset oligoimides have been prepared by the thermal polycondensation of 1,4-bis(2,3-dicarboxyl-phenoxy)benzene dianhydride with three different aromatic diamines in the presence of 4-phenylethynylphthalic anhydride as an end capping reagent. The aromatic diamines included 4,4′-oxydianiline, 2,2′-bis(trifluoromethyl)benzidine (TFDB) and 2-phenyl-4,4′-diaminodiphenyl ether ( p -ODA). Effects of the chemical structures and molecular weights of the oligoimides on their aggregated structures, melt processability as well as the thermal and mechanical properties of the cured films were then systematically investigated. X-ray diffraction results indicated that ODA series oligoimides and TFDB series oligoimides showed crystallinity; however, the asymmetrical p -ODA enables the p -ODA series oligoimides to exhibit amorphous forms. So the p -ODA based oligoimides with molecular weight of 750 g mol −1 showed much lower melt viscosity at a low temperature and the melt viscosity could maintain below 1 Pa s −1 after isothermal aging for 2 h at any temperature in the range of 220–280 °C by rheological measurements. © 2019 Wiley Periodicals, Inc.

A novel polysulfone was easily synthesized by alternating copolymerization of norbornene with sulfur dioxide (SO 2 ) via free radical copolymerization and coordination copolymerization. Compared with other olefin derivatives, norbornene is a cyclic olefin having a larger steric hindrance, which is easily copolymerized with SO 2 , and the obtained poly(norbornene sulfone)s have excellent thermomechanical and optical properties. The effect of the different polymerization methods on the copolymerization reaction was analyzed in detail. The results suggested that different polymerization mechanisms exist in the different polymerization methods and affect the thermal stability and optical properties of the polysulfone. © 2016 Wiley Periodicals, Inc.

Phosphorous flame retardants (PFRs) are common halogen-free flame retardants. However, the flame retardancy of PFRs has not been fully exploited. Herein, the synergistic flame retardant effect of a typical phosphorous compound, 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO), and organoclay on epoxy is studied. Results show that the peak of heat release rate (pHRR) and smoke production rate of modified epoxy resin (EP) with both 2.0 wt % phosphorus and 4.0 wt % organoclay are only 40% and 46% of that of neat EP resin, respectively, while the sole use of 2.0 wt % phosphorus only decrease the pHRR to 59% of that of neat EP resin. The structure and thermal decomposition behavior of as-prepared nanocomposites are analyzed, and a synergistic flame retardant mechanism is proposed. This investigation opens a new approach to obtain halogen-free EPs with higher flame retardancy and better overall properties than the EPs loaded with DOPO only. © 2016 Wiley Periodicals, Inc. J.

This study focuses on an improved synthesis of a branched poly (ethylene imine) (PEI)-modified cellulose-based adsorbent (Cell- g -PGMA-PEI). We aim to improve the adsorbent capacity by reducing side reaction of epoxide ring opening during graft copolymerization of glycidyl methacrylate (GMA) onto cellulose which increases the content of epoxy groups, anchors to immobilize branched PEI moieties. FTIR spectra provided the evidence of successful graft copolymerization of GMA onto cellulose initiated by benzoyl peroxide (BPO) and modification with PEI. The amount of epoxy groups of Cell- g -PGMA was 4.35 mmol g −1 by epoxy titration. Subsequently, the adsorption behavior of Cu(II) on cell- g -PGMA-PEI in aqueous solution has been investigated. The data from the adsorption kinetic experiments agreed well with pseudo-second-order model. The adsorption isotherms can be interpreted by the Langmuir model with the maximum adsorption capacity of 102 mg g −1 which was largely improved compared with the similar adsorbent reported. The dynamic adsorption capacity obtained from the column tests was 119 mg g −1 and the adsorbent could be regenerated by HCl of 0.1 mol L −1 . Results indicate that the novel pathway for the synthesis of Cell- g -PGMA-PEI exhibits significant potential to improve the performance of adsorbents in removal and recovery of Cu(II) from aqueous solution. © 2012 Wiley Periodicals, Inc.

Construction of a highly hydrophilic polymer surface with excellent long-term stability underwater is a great challenge. In this paper, a facile ultraviolet (UV) curing technique was employed to realize the three-dimensional (3D) grafting of poly(ethylene glycol) diacrylate (PEGDA, molecular weight: 400, 600, and 1000 g/mol) on a bisphenol A epoxy acrylate (BEA) sheet. The cross section morphology, surface chemical composition, and wettability of the sheets were monitored using an optical microscope, an attenuated total reflectance Fourier transform infrared spectroscope, and a water contact angle analyzer, respectively. The PEGDA-grafted epoxy sheets displayed a highly hydrophilic surface and meanwhile possessed excellent stability underwater, despite the molecular weight of PEGDA. In contrast, the PEGDA/BEA blend sheets are easily damaged underwater, due to strong swelling. In addition, the PEGDA1000-grafted BEA sheet demonstrated good antifouling performance in a natural marine environment. Nevertheless, its long-term antifouling is not satisfactory, being presumably due to hydrolysis or biodegradation of the PEG segments. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

Maleated glycidyl 3-pentadecenyl phenyl ether (M-GPPE) was synthesized from glycidyl 3-pentadecenyl phenyl ether (GPPE), a renewable derivative from cardanol, with maleic anhydride (MAH) by grafting copolymerization. The resulting M-GPPE was used as a functionalized plasticizer for a styrene–butadiene rubber (SBR)/carbon black (CB)/silica composite. The effects of M-GPPE on the development of the filler network, the extent of silica dispersion, the curing characteristics, and the mechanical performance of the composites were studied. Meanwhile, a comparative study was performed between M-GPPE and aromatic oil, a traditional plasticizer used in SBR filler formulations. Gel permeation chromatography and IR and 1 H-NMR analysis results confirmed the occurrence of the grafting reaction between GPPE and MAH and the potential structure of M-GPPE. The thermostability of GPPE was improved by grafting copolymerization with MAH, as shown by thermogravimetric analysis results. The presence of M-GPPE resulted in a shorter curing time and better aging properties in the SBR composite compared with GPPE. The mechanical properties, dynamic mechanical analysis, and transmission electron microscopy analysis showed that the maleate of GPPE could enhance the compatibility between SBR and silica, improve the dispersion of silica in SBR, and partially replace the aromatic oil in the SBR/CB/silica composite formulation. © 2014 Wiley Periodicals, Inc.

Feather keratin (FK), which can be extracted from waste feathers, is a kind of biodegradable and renewable protein resource and it has a great potential in the field of materials such as keratin sponges, films, and microcapsules. The aim of the current study was to investigate the blend modification of FK-based films using sodium alginate (SA). A series of FK-based films blended with different ratios of SA were prepared by the casting process. The cross-section of blend films had a compact and homogeneous structure and no distinct phase separation was observed, indicating the favorable compatibility between FK and SA. The result of DSC analysis, in which there was a change in crystal structure, confirmed the interaction between FK and SA in the blend films. The FTIR spectra pointed out that the main interaction between the two components would be through the formation of hydrogen bonds. The incorporation of SA to FK significantly enhanced the strength and maintained the extensibility of the resultant films. The water vapor permeability reached its lowest level when the ratio of FK to SA was 7:3. Moreover, the blend films exhibited a relatively high level of transparency with SA content below 30%. These improvements by incorporation of SA provided the potential to expand the application of FK-based films in packing and bio-medical industries. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

Cork/thermoplastic polyurethane (TPU) composites are promising sustainable materials for FDM 3D printing, but poor interfacial compatibility limits cork loading to ~3 wt%. To address this, a green strategy was proposed: cork powder was thermally treated at 300°C (modifying surface polarity and porous structure) and further functionalized with hexamethylene diisocyanate (HDI) to enhance compatibility. Melt-blended composite filaments achieved 10 wt% cork loading: heat treatment alone improved tensile strength by 20% and elongation at break by ~50%, while 6 wt% HDI addition boosted tensile strength by 42% and nearly doubled elongation. This low-cost, bio-based approach enables flexible, high-performance composites, realizing sustainable high-value utilization of natural materials in additive manufacturing.

Optically transparent amorphous copolyarylates based on tetramethylbisphenol A (TMBPA) and bisphenol B (BPB) were synthesized via low-temperature interfacial polymerization. These copolyarylates exhibited high solubility, with number average molecular weight ( M n ) of 1.48 × 10 4 –1.92 × 10 4 g/mol, weight average molecular weight ( M w ) of 6.64 × 10 4 –9.13 × 10 4 g/mol, polydispersity index (PDI) of 3.45–5.89, and intrinsic viscosity of 0.62–0.83 dL/g. Incorporation of TMBPA alters the thermal properties of the copolyarylates, decreasing thermal stability ( T 5% ) from 473.4°C to 444.4°C and char yield from 34.6% to 19.7%, but increasing the glass transition temperature ( T g ) from 202.9°C to 234.1°C. TG/FTIR and Py-GC/MS analysis revealed that methyl groups adjacent to the phenolic hydroxyl group promoted chain breakage and accelerated thermal decomposition. The main gaseous products included H 2 O, CO 2 , CO, CH 4 , and phenolic compounds. Tensile strength, tensile modulus, and elongation at break of copolyarylates ranged from 51.83 to 60.21 MPa, 1023.28 to 1283.14 MPa, and 32.9% to 53.6%, respectively. This study highlighted the solubility-thermal property balance, providing insights for designing processable high-performance polyarylates.

This study proposes a recycling strategy utilizing waste plastic bottles (PET bottle bodies and PE caps) to successfully fabricate a bilayer composite film, PET/(PE–TiO 2 ), which exhibits excellent passive radiative cooling performance and enhanced mechanical properties. The upper layer, consisting of highly reflective PET nanofibers fabricated via electrospinning, achieves a high solar reflectance (> 96%) across the solar spectrum (0.3–2.5 μm). The lower layer, a PE–TiO 2 composite prepared by melt blending, enhances the overall mechanical strength of the material. Systematic characterization demonstrates that the PET/(PE–TiO 2 ) bilayer film maintains high optical performance while significantly improving mechanical strength (breaking strength increased by > 5-fold) and thermal stability (decomposition temperature > 400°C). Both theoretical calculations and experimental validation confirm that the material achieves a net cooling power exceeding 100 W/m 2 under standard solar irradiation (1 kW/m 2 ). Practical applications demonstrate surface temperature reductions of approximately 10°C for the human body and 5.3°C for electronic devices. This work not only achieves efficient synergistic recycling and value-added utilization of PET and PE but also provides a new approach for developing low-cost, high-performance, and environmentally friendly passive cooling materials, with broad application prospects in personal thermal management, electronic thermal regulation, and building energy efficiency.

Poly(methyl methacrylate) (PMMA) exhibits a high coefficient of friction, limiting its use in tribological applications. To address this, graphene oxide (GO), synthesized via the Hummers method, is functionalized with silane KH570 to enhance its compatibility and subsequently incorporated into PMMA through in situ bulk polymerization, resulting in PMMA/KH570-GO composites. The structural, morphological, and functional properties of the composites are characterized using x-ray diffraction (XRD), Fourier-transform infrared (FTIR) spectroscopy, Raman spectroscopy, scanning electron microscopy (SEM), and atomic force microscopy (AFM). Mechanical and tribological behaviors are assessed through tensile and pin-on-disc tests. The results indicate that the addition of 0.06 wt% KH570-GO enhances tensile strength by 13.4%, achieving a value of 76.25 MPa, and significantly reduces the coefficient of friction from 0.7 to 0.25, compared to pure PMMA. Beyond this threshold, a higher KH570-GO loading of 0.20 wt% diminished the tensile strength to 59.23 MPa. The optimal content, in contrast, improved mechanical properties and promoted the development of a lubricating graphitic film during friction, which collectively contributed to a marked enhancement in tribological performance.
