“…TiGr has received widespread attention because of the usage of lightweight titanium and high modulus of carbon fiber‐reinforced thermoplastic PEEK resin prepregs. Because TiGr has excellent flame retardancy, high damage tolerance and corrosion resistance, good impact resistance, easy forming, and recyclability, TiGr has been used in some commercial and military aircrafts .…”

This article discusses about the significance of graphene oxide (GO) deposition on the surface of a titanium plate by electrophoretic deposition (EPD) method to improve the adhesive strength of Ti/polyetheretherketone (PEEK) interfacial adhesive. Firstly, the anodic EPD method was applied to a water dispersion solution of GO, and then the morphology and the properties of titanium plate surface were characterized by scanning electron microscopy and contact angle measurements before and after GO deposition. Furthermore, the changes in the properties of GO after heating at 390°C were characterized by Raman and Fourier transform infrared spectroscopies. According to the results of single lap tensile shear test, the adhesion strength of Ti/PEEK interface after the anodization and deposition of GO was 34.94 MPa, an increase of 29.2% compared with 27.04 MPa of sample with only anodization. Also, the adhesion strengths were 58.1 and 76.5% higher compared with the samples of only GO deposited (22.1 MPa) and pure titanium (19.8 MPa), respectively. POLYM.

“…Since all applied procedures are scalable, simple, and do not use expensive chemicals or sophisticated technical steps, the proposed procedure could be an unpretentious route for mass-production of icephobic surfaces on the materials, commonly used in the aerospace industry (e.g., PEEK/CF). In addition, the applied experimental procedure allows us to attach the fluorine-containing moieties to the surface of PEEK/CF in a short way and with the formation of stable covalent bonds. − …”

The design of the icephobic surface represents an urgent challenge in the field of surface engineering with high application potential. In this work, we proposed the introduction of icephobic surface properties on the technically relevant materialpolyetheretherketone/carbon fibers (PEEK/CF) composite. The developed method utilizes the simple and scalable electrochemical etching to induce a significant increase of surface roughness and subsequent chemical grafting for attachment of hydrophobic fluoro-containing chemical moieties. The surface morphology was characterized at different scales, using the profilometer, confocal microscopy, and atomic force microscopy (AFM) measurements. The success of chemical grafting was confirmed using the X-ray photoelectron spectroscopy (XPS) and infrared spectroscopy (IR) measurements. The surface properties were tuned to reach the superhydrophobic and Cassie–Baxter water drop states, minimizing the contact area between the drop and sample surface. The icephobic surface properties were tested through the measurements of the time delay of ice formation, precooled drop slipping, and estimation of ice removal force. It was convincingly demonstrated that optimal combination of physical and chemical treatment allows us reaching the icephobic properties on PEEK/CF composite. The main advantages of proposed procedure are its simplicity and scalability, which makes it highly attractive for the practical introduction of icephobic properties in the field of aircraft materials.

“…On industrial metals such as iron, the bonds are even weaker, making this reaction almost useless for practical purposes. However, the reduction of diazonium salts is a way to form strong bonds between metals and organic molecules. − Also, polymerizing a vinyl compound in the presence of a diazonium has been first described by Mévellec et al…”

Covalent grafting of dielectric films containing polyhedral oligomeric silsesquioxane (POSS) on the surface of Cu(111) is performed by a one-step electrochemical reduction of diazonium salts. This method is efficient and economic and performs in a proton-polar solvent of deionized water and tetrahydrofuran (THF), where the monomer employs an octavinylsilsesquioxane (OVS) containing a POSS core. The eight vinyl bonds contained in OVS are used to participate in aryl radical-initiated polymerization reactions to form films. The formed film is dense and covers the copper surface completely and uniformly. The thickness of the film can be controlled by adjusting the reaction time. The components of the films are mainly polynitrophenyl (PNP) or polyaminophenyl (PAP) as well as poly(octavinylsilsesquioxane) (POVS), and the POVS content could be adjusted by the applied voltage. The introduction of POSS prevents the copper surface from being oxidized and often gives the film good properties such as good dielectric properties, mechanical properties, and thermal properties. In addition, the presence of Cu–O–C and Cu–C bonds between the film and copper interface is confirmed at different film thicknesses by X-ray photoelectron spectroscopy (XPS), which allowed the construction of covalent bonds between metal and nonmetal, further enhancing the bonding between the film and copper. Organic films prepared by electrochemical reduction of diazonium salts using OVS as a monomer will have potential significance for the future development of the electronics industry.
