The composite or hybrid of organic and inorganic materials is one of the common ways to improve the properties of photoelectric functional materials. Perylene bisimide (PBI) derivatives, as large π-conjugated organic small molecules, are a class of photoelectric functional materials with excellent performance. However, there were few reports on PBIs in the electrochromic field due to the difficulty of film-forming caused by their generally poor solubility. Here, water-soluble PBI derivatives (PDI-COOH and PCl-COOH) were synthesized. The hybrid films (ZnO@PDI-COOH/PCl-COOH) formed by the coordination bond and π–π stacking were prepared via a simple solution immersion method. Fourier transform infrared spectrometry and X-ray diffraction as well as scanning electron microscopy, and energy-dispersive spectrometry results further confirmed the formation of hybrid films. At the same time, electrochemical and spectroelectrochemical analyses revealed that the films have reversible redox activity and cathodic electrochromic properties, which can change from orange-red to purple. The ZnO@PDI-COOH hybrid film formed by coordination bonds exhibits fast switching times (1.7 s colored time and 2.6 s bleached time), good stability (retain 92.41% contrast after 2400 cycles), a low driving voltage (−0.6–0 V), and a high coloration efficiency (276.14 cm2/C). The corresponding electrochromic devices also have good electrochromic properties. On this basis, a large-area (100 mm × 100 mm) electrochromic display device with fine patterning was fabricated by using the hybrid film, and the device shows excellent reversible electrochromic performance. This idea of constructing organic–inorganic hybrid materials with coordination bonds provides an effective, energy-saving, and green method, which is expected to promote the large-scale and fine production of electrochromic materials.

A simple and versatile route for industrial scale synthesis of adipicdihydrazide (ADH)/polymer hybrids with excellent performance of formaldehyde degradation is proposed in this paper. The ADH compound is uniformly dispersed in poly(methyl methacrylate-butyl acrylate-methacrylic acid) (P(MMA-BA-MAA)) latex, which is validated by UV and dispersibility tests. The results illustrate that ADH has excellent compatibility and dispersion stability without affecting the film formation of the polymer latex. Furthermore, scanning electron microscope (SEM) and mapping analysis of the hybrid films also demonstrate that ADH is homogenously dispersed in the polymer matrix. Compared with neat polymers, the thermal properties of hybrid films are improved, for example,T0.5increases by 8.3 °C. According to qualitative tests of the 4-amino-3-hydrazino-5-mercapto-1,2,4-triazol-red/green/blue (AHMT-RGB) method, the hybrid films demonstrate high formaldehyde removal efficiency. On the basis of the semi-quantitative test of Fourier Transform infrared spectroscopy (FTIR) measurements, the rate of formaldehyde degradation can reach 1.034 × 102mol/(h·m3) for the hybrid film with 5 wt% ADH.Keywords:adipicdihydrazide;formaldehyde degradation;polyacrylate latex;hybrid film

The construction of organic-inorganic hybrid materials has shown great potential for the development of multifunctional superior polymer-based composites. The inadequate thermodynamic property and mechanical strength of polyacrylate (PA) restrict its further application. To address this issue, the seed polymer emulsion was prepared by emulsion polymerization of 3-(trimethoxysilyl) propyl methacrylate (MPS)-modified silica (SiO 2 ) with acrylic monomer, serving as a stabilizer for Pickering emulsion. The reactive C C bond (unsaturated double bond from MPS) introduction induced the copolymerization between MPS-modified silica and polymer monomers, enhancing the interaction between silica and polymer matrix. Subsequently, the core/shell-PA/modified SiO 2 (CS-PA/modified SiO 2 ) emulsion was prepared by Pickering emulsion polymerization. This gradient-layered structure reduces internal friction and enhances the relative flow between latex particles, resulting in the uniform particle size distribution (202 nm) and a narrow polydispersity of 0.025. The results of storage, centrifugation and calcium ion stability tests demonstrated the exceptional stability of CS-PA/modified SiO 2 latex particles. The hydrophobic surface of hybrid latex films could be obtained from the CS-PA/modified SiO 2 emulsion. The tensile strength and elongation at break of the films were determined as 6.25 MPa and 573.54 %, respectively. Additionally, the heat resistance index (HRI) of the film exceeded 165 ℃, signifying exceptional thermal stability. This work provides a convenient strategy for design and fabrication of hybrid latex films with excellent performances for packaging or conservation of cultural heritage.

Hybrid nanocomposite films of magnesium oxide (MgO) in fluorinated polyimide (PI) from 4, 4′-(hexafluoroisopropylidene) diphthalic anhydride (6FDA) and 4, 4′-Diaminodiphenyl ether (ODA) have been successfully fabricated via an in situ sol–gel polymerization technique. The MgO content in hybrid films was varied from 0 to 5 wt%. The hybrid films were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), ultraviolet–visible (UV–Vis) spectroscopy and thermal gravimetric analyses (TGA). The results of FTIR, XRD and FESEM showed that the MgO nanoparticles were well dispersed in the polymer matrix due to the coordination between the carbonyl group of polymers and Mg atom, and the as-prepared hybrid films exhibited excellent optical transparency in the visible region and good UV-shielding properties in the UV region. Although the thermal stability of the hybrid films is slight inferior to pure PI, it is still good for the practical application below the temperature of 300 °C.

Transparency is an important characteristic for film products, yet it remains a formidable challenge in the realm of organic-inorganic hybrid and composite materials. Herein, we report the development of transparent TiO 2 /cellulose hybrid films through an innovative in situ synthesis method, integrating TiO 2 formation during the regeneration process of cellulose. These hybrid films exhibit exceptional transparency, rivaling that of pure regenerated cellulose films, while simultaneously boasting a robust UV-shielding capacity. The successful integration of TiO 2 into the hybrid films was validated through XPS and Raman analysis, while XRD patterns revealed a decrease in the crystallinity of regenerated cellulose due to the introduction of TiO 2 . To investigate the dye removal capabilities of these films, methylene blue was chosen as a model dye. Our experiments indicate that the incorporation of TiO 2 significantly enhances the dye absorption capacity and catalytic photodegradation activity of the regenerated cellulose film. Furthermore, antibacterial tests targeting Escherichia coli and Staphylococcus aureus revealed that these hybrid films exhibit remarkable antibacterial properties, effectively inhibiting bacterial growth in both dark and UVC irradiation conditions. Collectively, these results underscore the promising applications of TiO 2 /cellulose hybrid films in diverse fields, including dye wastewater treatment and active food packaging. Graphical abstract

Novel organic–inorganic hybrid amorphous thin films were synthesized by linking lanthanide (Tb 3+ , Eu 3+ ) complexes through 3,4-bis(3-(triethoxysilyl)propylcarbamoyloxy)benzoic acid using sol–gel method. These inorganic–organic hybrids were characterized in detail by Fourier transform infrared spectroscopy, wide angle X-ray diffraction, themogravimetric analysis, scanning electron microscope, and fluorescence spectra. The above research results indicate that the hybrids possess high thermal-stability, amorphous structure features and especially favorable luminescent performances, such as long luminescent decay lifetime, high quantum yield etc.

The reduced graphene oxide/boron nitride (RGO/BN) hybrid film materials were prepared via ultrasonic blending, followed by the vacuum filtration film-forming and chemical reduction process. The fabricated free-standing RGO/BN hybrid films could combine the advantages of highly conductive RGO and pseudocapacitive BN. Notably, the optimized 1:1 RGO/BN hybrid film electrode delivered an areal capacitance of 513.4 mF cm −2 at 1 mA cm −2 , which was four times larger than that of RGO film. The introduction of BN drastically improved the areal capacitance and also demonstrated excellent capacitance retention. Furthermore, a symmetric supercapacitors device was constructed using the 1:1 RGO/BN hybrid film as two symmetrical electrodes. An areal energy density of 6.8 µWh cm −2 was attained at a power density of 800 µW cm −2 . This development opens avenues for the facile manufacturing of hybrid film as high-performance energy storage materials.

High-performance electromagnetic interference (EMI) shielding materials with lightweight, multi-resistant properties and superior, tunable EMI shielding performance are urgently needed for next-generation integrated electronic and communication systems, particularly in portable smart devices and artificial intelligence applications. In this work, hollow h-MXene/ANF backbones with a continuous shielding network were fabricated using a facile vacuum-assisted filtration process combined with a sacrificial template method. The structurally engineered h-MXene/ANF hybrid films achieved outstanding EMI shielding effectiveness (EMI SE) of 78.9 dB and EMI specific shielding effectiveness per unit thickness (SSE/t) of 15703 dB·cm 2 ·g –1 . These exceptional properties are attributed to high ohmic losses, multiple internal reflections, polarization relaxation, and efficient losses in the hollow MXene conductive layer, facilitated by impedance mismatches within the sandwich structure. Notably, the EMI SE performance can be tuned by adjusting the content of hollow MXene microspheres. In addition, extensive hydrogen-bonding interactions between the high-performance ANF and MXene contribute to enhanced mechanical properties, including tensile strength of up to 37 MPa, as well as excellent thermal stability and self-cleaning capabilities. Overall, the sandwich-structured h-MXene/ANF hybrid films exhibit superior mechanical strength, multi-resistant properties, and ultra-high, tunable EMI shielding performance, making them promising candidates for advanced EMI shielding in next-generation portable smart electronic devices.

Nacre-like hybrid films based on N -succinyl chitosan (NSC), sodium alginate (SA) and lanthanide ions were fabricated via coordination interactions. In this work, the binary building blocks (NSC and SA) were self-assembled into aligned hydrogel films by coordination with lanthanide ions, and hierarchical NSC-SA hybrid films were obtained upon drying. Two species of lanthanide ions (Gd 3+ and Yb 3+ ) were used to fabricate the hierarchical NSC-SA hybrid films. The as-prepared NSC-SA hybrid films exhibit high tensile strength and stability. The tensile strength and toughness of as-prepared hybrid films reach 122.10 MPa and 3.89 MJ m −3 , respectively. Meanwhile, the well-aligned lamellar microstructures also exhibit a good light transmittance. The highest light transmittance reaches 92% for NSC-SA hybrid films at 760 nm. This fabrication method for hierarchical NSC-SA hybrid films is innovative due to the utilization of rare earth coordination bonding, and can serve as the basic strategy for the construction of high-performance composites in the near future.

In this work, single-layer layered double hydroxide (LDH) nanosheets were prepared by exfoliation of highly crystalline Co−Al−NO3 LDH. Graphene oxide (GO) nanosheets were prepared by the exfoliation of natural graphite oxides in water. By utilizing the hydrogen-bonding layer-by-layer self-assembly method, poly(vinyl alcohol) (PVA) hybrid films with highly oriented GO and LDH were fabricated. By a simple and effective in situ reduction process, multilayer nanocomposite films containing monolayer dispersed graphene and LDHs can be obtained. It was found that the π-conjugation network within the graphene nanosheets was gradually recovered during the reduction process and a critical time for the formation of conductive paths for electron transfer was obtained. The relatively complete reduced hybrid film exhibited significantly improved electrical conductivity compared with the unreduced one. These heterogeneous composite films with monolayer dispersed and aligned graphene and LDHs are expected to find potential applications in electrodes and multifunctional nanocomposites.

To broaden the application of polyimide materials, adenine-based polyimide/nano-silica hybrid films were prepared via sol-gel method without using coupling agents. Adenine-based diamine, 9,10-bis(4-aminopheny)adenine ( p -APA), was introduced to polymerize with 3,3′,4,4′-tetracarboxydiphthalic ether dianhydride (ODPA) to synthesize polyimide (API) matrix. The compatibility between the polymer matrix and silica was improved by hydrogen bonding between NH group in p -APA and Si OH group in silica. Systematic studies showed that API hybrid films possess high transparency and outstanding thermal properties even though the doping content was up to 20 wt% (glass transition temperature ( T g ): 328 °C, maximum decomposition occurring temperature ( T max ): 603 °C (N 2 ), coefficient of thermal expansion (CTE): 16.60 ppm/ o C).

The flexible, strong, and tough white-light-emitting (WLE) hybrid films are highly demanded in large-scale displays, including TV sets, monitors, and electronic interactive devices. In this work, a kind of WLE hybrid film was fabricated from hyperbranched poly(amido amine) (HPAMAM) and nanoclay with the incorporation of riboflavin (VB 2 ) and rhodamine B (RhB). The fluorescence emission of HPAMAM was partially absorbed and effectively transferred into green and red color, which combined into a bright white light with the residue blue fluorescence. Due to the alignment of nanoclay inside the HPAMAM matrix, in addition to the strong interaction among the HPAMAM molecules and that between HPAMAM and nanoclay, this hybrid film shows to be strong and tough. The mechanical strength is about 20 MPa and the elongation is about 30%. It is convinced that this hybrid film is promising in flexible large-scale displays. © 2017 Wiley Periodicals, Inc. J. Appl.
