“…It can be seen that there was vibration of an OH bond at 531.8 eV. [ 56 ] In the XPS image in Figure 3d, we can see a peak caused by the vibration of –NH 2 , and the appearance of this group mainly comes from the chemical composition of CS, [ 53 ] indicating that CS successfully interleaved with other materials.…”

At present, polymers such as polyethylene glycol (PEG) and chitosan (CS) are widely studied because of their excellent lubricating properties. Herein, powder combinations of different mass ratios are obtained by changing the mass of CS, and polymer films are obtained by hot pressing on the surface of the aluminum disk after microarc oxidation (MAO). The structure and crystallinity of the polymer composite film are characterized by X‐ray diffraction (XRD), Fourier‐transform infrared (FTIR), and X‐ray photoelectron spectroscopy (XPS), which show that there is no chemical reaction between various substances. The tribological properties of the composite film are evaluated. Experiments show that when the mass ratio of polyvinyl alcohol (PVA), PEG, and CS is 5:5:1.5, the composite film has excellent lubrication performance, and the friction coefficient reaches 0.068 under long‐time running in. This effect meets the social requirements for lubrication performance to a certain extent and is expected to replace some mature solid lubricants.

“…For the C1 s analysis diagram, it can be seen intuitively that there was a CH bond vibration at 284 eV. [ 52,53 ] The peak at 284.7 eV can be attributed to the tensile vibration of the CC bond, [ 54 ] and the peak at this moment was the most obvious, mainly from PVA and PEG. At the same time, C–O vibration was detected at 286 eV.…”

“…A bare surface without prior functionalization with a CTA was also utilized for the preparation of a polyvinyl alcohol (PVA)-based hydrogel. The PVA-based hydrogel was immersed in the reaction mixture of PC (i.e., Ru(bpy) 3 Cl 2 , 345,346 fluorescein, 347 EY, 348 and aluminum phthalocyanine chloride 349 ), CTA, monomers, and TEA. It was proposed that alkoxyl radicals generated from PVA by a one-electron oxidized PC or by irradiation participated in PET-RAFT polymerization.…”

“…In both cases, high grafting density where achieved, up to 50-60%, and the final material was effective in both anti-protein adsorption and anti-cell capacity (>50%) with no cytotoxicity. Finally, Zhongkuan Luo and co-workers [ 114 ] grafted glycidyl methacrylate (GMA) and 2-hydroxypropyltrimethyl ammonium chloride chitosan (HACC) on the surface of PVA hydrogel for artificial cornea production. This work is the demonstration of the orthogonality of PET-RAFT polymerization with post-modification reactions.…”

Photochemistry has attracted great interest in the last decades in the field of polymer and material science for the synthesis of innovative materials. The merging of photochemistry and reversible-deactivation radical polymerizations (RDRP) provides good reaction control and can simplify elaborate reaction protocols. These advantages open the doors to multidisciplinary fields going from composite materials to bio-applications. Photoinduced Electron/Energy Transfer Reversible Addition-Fragmentation Chain-Transfer (PET-RAFT) polymerization, proposed for the first time in 2014, presents significant advantages compared to other photochemical techniques in terms of applicability, cost, and sustainability. This review has the aim of providing to the readers the basic knowledge of PET-RAFT polymerization and explores the new possibilities that this innovative technique offers in terms of industrial applications, new materials production, and green conditions.
