Intelligent fabrics have been widely investigated owing to their great potential for applications in the field of wearable electronics. Despite significant progress having been made in research on intelligent fabrics, it is still a challenge to combine stable color rendering and sensing capability. In this study, an effective method was developed to prepare a double-sided color composite fabric with hydrophobic water vapor permeability, stable color rendering and excellent sensing properties at different temperatures. The intelligent structural color-changing properties of blue-, green- and orange-colored fabrics are based on monodisperse polystyrene supported silica (PS@SiO 2 ) microspheres of 195, 286 and 301 nm size, respectively. Meanwhile, the structural color does not change as the angle changes. Then, polydimethylsiloxane-modified waterborne polyurethane and ionic liquid were used as adhesives, which not only enhance the interfacial interaction between PS@SiO 2 microspheres and fabric, but also endow the composite fabric with sensing performance and hydrophobicity. When applied to human joint motion detection, the composite fabric-based sensors show good sensitivity (strain coefficient ~ 3.91) and excellent cycling stability (300 times). Simultaneously, the composite fabric has good hydrophobicity (~134°) and excellent water permeability (~410 g m −2 d −1 ). More interestingly, the structural color and sensing performance still hold up well under varying ambient temperatures (−30 to 90 °C) or the mild effects of soaking, washing and freezing. This research provides a novel method for the development of intelligent fabrics with structural color and sensing capability under a range of ambient temperatures. © 2026 Society of Chemical Industry.

Polyurea (PU) elastomers have attracted considerable attention in the field of protective polymeric coatings. In this work, a dithiol-terminated boronic ester was synthesized and used to incorporate dynamic boron–oxygen (B–O) bonds in the PU main chain based on thiol isocyanate while amino-terminated polydimethylsiloxane (PDMS) was introduced to retain good chain flexibility. The modified PU elastomer was found to have a microphase-separated structure in which the hard blocks served as physical crosslinks. The glass transition temperature ( T g ) slightly increases when dynamic B–O bonds exist while further introduction of PDMS soft segment can lower T g to −55.63 °C. The introduction of dynamic B–O bonds and diminished hydrogen bonding led to a decrease in mechanical strength and elongation at break. Interestingly, the simultaneous incorporation of PDMS and dynamic B–O bonds is favorable for strain rate dependence and suppressing stress relaxation. The potential for bond-exchange interactions between the dynamic B–O bonds and hydroxyl groups on metal surfaces substantially improved the adhesion of the PU elastomer to metal substrates. Therefore, our work can offer valuable insights for the structural design of functional PU coatings tailored for anti-impact applications. © 2024 Society of Chemical Industry.

Assembling various organic building blocks through carbon–carbon double-bond linkages is highly efficient for constructing high-performance organic semiconductors. Microporous/nanoporous structures can provide robust mass collection accommodation and reactive reaction sites. Here, we report the synthesis of a series of vinylene-linked conjugated porous polymers by Knoevenagel condensation of a tetratopic monomer tetramethyl-2,2′-bipyridine with different ditopic monomers. The presence of the 2,2′-bipyridine building blocks created π-extended conjugation polymeric frameworks, substantial n -type semiconducting properties and coplanar conformation. These frameworks also exhibit strong electron-deficient characters and finely tuned energy levels. Upon visible light irradiation, they exhibited the highest activity of hydrogen peroxide generation up to 1413 μmol h −1 g −1 in pure water. Their excellent recycling and reusability suggest their potential applications in green chemical transformation. © 2025 Society of Chemical Industry.

A novel bio-based benzoxazine resin (diphenolic acid/furfurylamine benzoxazine resin, PDPA-F-Boz) was prepared by using bio-based diphenolic acid, furfurylamine and paraformaldehyde as raw materials. The structure of DPA-F-Boz monomer was characterized by Fourier transform infrared spectroscopy, 1 H NMR and 13 C NMR, and then its curing reaction and the thermal stability of the cured PDPA-F-Boz were analyzed. Compared with the traditional fossil-based benzoxazine (bisphenol A/aniline benzoxazine, BPA-A-Boz) and the bio-based benzoxazine (diphenolic acid/aniline benzoxazine, DPA-A-Boz), DPA-F-Boz monomer showed the lowest curing temperature, and PDPA-F-Boz had the highest residual char ratio at 800 °C and the lowest degradation rate at the peak temperature. Meanwhile, the total heat release, peak heat release rate and heat release capacity of PDPA-F-Boz were much lower than those of PBPA-A-Boz and PDPA-A-Boz. Thus, PDPA-F-Boz showed excellent low-temperature curing ability and thermal stability. © 2019 Society of Chemical Industry

Acquiring freshwater from seawater, the solar interfacial vapor generator (SIVG) offers a passive and decentralized approach to addressing water shortage problems. However, the performance of current SIVGs is greatly restricted by the disadvantages of poor controllability and manipulation of seawater transport porous structure and the evaporation interface. To realize rapid seawater replenishment and highly efficient vaporization, we developed a novel polyethylene terephthalate (PET) SIVG with small-sized oriented pores and an ultrathin photothermal conversion layer that exhibited a highly efficient water evaporation rate under both simulated solar and outdoor sunlight illumination. The well-arranged and highly oriented pores with controllable size in PET acted as a confined mass transfer fluid pump to spontaneously transport seawater to the evaporation layer, in which a maximum height of 68 mm via the capillary rise mechanism was reached. The resultant PET layer possessed a low density of 0.08 g cm −3 that exhibited an ideal floating performance to steady the interfacial evaporation. Moreover, due to the superior dispersion structure in the photothermal conversion layer, the surface temperature of the SIVG greatly increased to 101.2 °C within 45 s, and the evaporation rate reached 1.26 kg m −2 h −1 . This work provides a novel strategy for preparing a high performance SIVG and also paves an innovative way for obtaining fresh water. © 2025 Society of Chemical Industry.

Current methods for superhydrophobic modification of polypyrrole (PPy) are typically complex and challenging to implement at scale. To address this limitation, this study developed a durable superhydrophobic photothermal coating by modifying PPy through a facile surface treatment method. The successful modification was confirmed by TEM and Fourier transform infrared spectroscopy analyses, revealing a uniform polymer film on PPy surfaces. When combined with epoxy resin at an optimal mass ratio of 0.3, the coating exhibited well-defined micro/nano structures with a contact angle of 153.6°. The coating maintained good chemical stability and mechanical durability. Under simulated conditions, the coating demonstrated excellent photothermal conversion efficiency and cycling stability. In freeze–thaw testing, coated concrete specimens showed significantly enhanced frost resistance, with mass loss reduced to one-fifth compared to uncoated samples after 50 cycles. This innovative coating system provides an effective strategy for improving concrete durability in harsh environments. © 2025 Society of Chemical Industry.

The preparation of polymer therapeutics capable of synergistic co-delivery systems for chemotherapeutic drugs and genes remains a tough problem in cancer therapy. Herein, we develop a novel co-delivery system for chemotherapeutic drugs and genes. Paclitaxel (PTX) was covalently grafted onto the cationic copolymer poly(ethylene glycol)- b -poly( l -lysine) (PEG- b -PLL) via a disulfide bond, and then CXCL1 shRNA was loaded on the cationic micelles PEG- b -PLL-SS-PTX by electrostatic interaction to construct PEG- b -PLL-SS-PTX/pDNA complex. The chemical structure of the complex was confirmed by gel permeation chromatography, 1 H NMR and Fourier transform infrared spectroscopy. The binding ability of the cationic micelles and pDNA was detected by gel retardation assay. In vitro gene transfection studies revealed an enhanced gene transfection efficiency due to the co-delivery of PTX and pDNA to ovarian cancer cells. In vitro and in vivo data demonstrated that the co-delivery complex exhibited a synergistic role of chemotherapy and gene therapy and possessed enhanced antitumor effects. The strategy of using drug-loaded cationic micelles as gene delivery carriers is a versatile approach to construct a co-delivery system, which might result in more efficient cancer therapy. © 2022 Society of Industrial Chemistry.

A rather low crystallization rate has greatly limited the application of poly( l -lactide) (PLLA) in many fields. Thus, functionalized cellulose nanoparticles (CPNs) were prepared based on cellulose aerogel through a novel and simple approach and were then applied as biobased nucleating agents to improve the crystallization rate of PLLA. First, isolated individual CPNs with a mean diameter around 37.2 nm and regular circular shape were obtained. Subsequently, PLLA based nanocomposites with various contents of CPNs were prepared by solution blending. As a result, CPNs promoted the crystallization rate of PLLA significantly. Compared with that of neat PLLA, the crystallinity ( X c ) of the nanocomposites increased dramatically more than 30 times to 36.65% at a CPN loading of 0.5 wt%, and the half-crystal time ( t 1/2 ) at 130 °C decreased by about 91%. Furthermore, due to the presence of CPNs, which provided a large number of nucleation sites in the PLLA matrix, the chain conformational and crystallization kinetics behavior of the PLLA based nanocomposites during isothermal crystallization were changed in the early stages, and based on this result a proposal for the nucleation process for CPNs in a PLLA matrix is presented. © 2018 Society of Chemical Industry

Six new bis(benzimidazolyl) monomers containing ether, sulfonyl and ketone groups were synthesized efficiently. A series of poly( N -arylenebenzimidazole)s were prepared using an aromatic nucleophilic displacement reaction that removed the N–H sites from the novel bis(benzimidazolyl) derivatives with activated aromatic difluorides in sulfolane. The reaction was carried out at 210 °C in the presence of anhydrous potassium carbonate. All resulting polymers showed essentially amorphous patterns. This was consistent with the calculated results. Differential scanning calorimetry and thermogravimetric measurements showed that the polymers had high glass transition temperatures (>240 °C), good thermostability and high decomposition temperatures (>400 °C). These novel polymers also showed easy solubility. © 2013 Society of Chemical Industry

Double crystalline poly(trimethylene terephthalate)/poly(ethylene oxide terephthalate) copolymers (PTT/PEOT), with PTT content ranging from 16.5 to 65.5 wt%, were synthesized by melt copolycondensation. The morphological transformation of samples from microphase separation to macrophase separation was investigated by gel permeation chromatography and transmission electron microscopy. Differential scanning calorimetry and in situ wide-angle X-ray diffraction suggested that all copolycondensation samples displayed double crystalline behavior. The melt-crystallization peak temperatures ( T m, c values) of PTT chains monotonously increased with increasing PTT content and were higher than that of homo-PTT when the content of PTT was above 30.6 wt%. Interestingly, T m, c values of PEOT chains were also increased with increasing PTT content. Polarized optical microscopy revealed that all copolycondensation samples studied could form ring-banded spherulites and band spacing increased with increasing T c values. In addition, band spacing decreased with increasing PTT content at a given T c . Strangely, although PEOT was the main component in all copolycondensation samples, spherulitic morphology formed by the advance crystallization of PTT did not change after PEOT crystallization. Only a subtle change of quadrant tones was detected. © 2012 Society of Chemical Industry

Octavinyl polyhedral oligomeric silsesquioxane (OVPS) is used as the crosslinker instead of N , N ′-methylenebisacrylamide (BIS) to copolymerize with 2-(dimethylamino)ethyl methacrylate (DMAEMA) or DMAEMA and N -isopropylacrylamide (NIPAM) to prepare hybrid hydrogels: P(OVPS- co -DMAEMA) and P(OVPS- co -DMAEMA- co -NIPAM). The prepared hydrogels are transparent and show dual response to temperature and pH. The hydrogels were characterized using Fourier transform infrared spectroscopy, scanning electron microscopy, X-ray diffraction, differential scanning calorimetry, thermogravimetric analysis, dynamic mechanical analysis and tensile tests. Their mechanical properties, swelling ratio, deswelling and reswelling behaviors as well as drug release properties were investigated. The results indicate that OVPS can be incorporated into polymer networks in proportion to feed ratios. The P(OVPS- co -DMAEMA) hydrogel exhibits more homogeneous interior structure, higher swelling ratio and faster response than the conventional hydrogel prepared with BIS. Moreover, the incorporation of OVPS enhances the compression and tensile properties of the hydrogels. The feed ratios of OVPS and NIPAM have a great effect on volume phase transition temperature, thermal sensitivity, swelling behavior, mechanical properties and drug release properties of the hybrid hydrogels. The prepared dual-responsive OVPS-containing hydrogels are expected to be used as biomedical materials in drug release and tissue engineering. © 2014 Society of Chemical Industry

Super-toughened poly( l -lactic acid) (PLLA) was prepared by reactive blending of PLLA with poly(ϵ-caprolactone) (PCL), glycerol and 4,4′-methylenediphenyl diisocyanate. The reactive interfacial compatibility between PLLA and the formed crosslinked polyurethane (CPU) in the PLLA matrix was studied in detail. The morphology and the toughness of the blends can be tuned by changing the CPU content. The results indicate that the impact strength of PLLA shows a tendency to higher values with the increasing PCL content up to 20 wt%. The notched impact strength of the blend with 20 wt% PCL increases to 55.01 kJ m −2 , which is 24.9 times higher than that of neat PLLA. The elongation at break is also increased from 5% to 139.4%, indicating the brittle − ductile transition. The increased interfacial binding strength through the reactive interfacial compatibility and the formation of a CPU network in the PLLA matrix account for the improved toughness of PLLA/CPU blends. Dynamic mechanical analysis results indicate that the compatibility between PLLA and CPU is improved with increasing CPU content resulting in the formation of more interfacial phase. In addition, rheological property measurements indicate that the improvement in storage modulus and complex viscosity is ascribed to the formation of a CPU network in the PLLA matrix. © 2016 Society of Chemical Industry
