“…), nonmetallic nanoparticles (silica nanoparticles, zirconium dioxide nanoparticles, etc. ), , and colloidal particles, are able to significantly change the surface properties and endow the substrates with new properties. For example, surface modification of the nanoparticles with polymer brushes can improve the stability and impart a wealth of properties such as corrosion protection, colloidal stability, adhesive properties, irritation responsiveness, lubrication, and friction properties.…”

“…This approach provides a facile and efficient strategy for the synthesis of polymer brushes. Dong and co-workers fabricated polymer brushes on the surfaces of zirconium dioxide (ZrO 2 ) particles by UV-induced polymerization . The polymer brushes on the NPs effectively prevent the aggregation of the pristine ZrO 2 , and the NPs could be used as a carrier for polymetallic oxides (POMs).…”

For over two decades, polymer brushes have found wide applications in industry and scientific research. Now, polymer brush research has been a significant research focus in the community of polymer science. In this review paper, we give an introduction to the synthesis, self-assembly, and applications of one-dimensional (1D) polymer brushes on polymer backbones, two-dimensional (2D) polymer brushes on flat surfaces, and three-dimensional (3D) polymer brushes on spherical particles. Examples of the synthesis of polymer brushes on different substrates are provided. Studies on the formation of the surface nanostructures on solid surfaces are also reviewed in this article. Multicomponent polymer brushes on solid surfaces are able to self-assemble into surface micelles (s-micelles). If the s-micelles are linked to the substrates through cleavable linkages, the s-micelles can be cleaved from the substrates, and the cleaved s-micelles are able to self-assemble into hierarchical structures. The formation of the surface nanostructures by coassembly of polymer brushes and “free” polymer chains (coassembly approach) or polymerization-induced surface self-assembly approach, is discussed. The applications of the polymer brushes in colloid and biomedical science are summarized. Finally, perspectives on the development of polymer brushes are offered in this article.

“…SIPGP is a simple, solvent-free bulk/surface photografting first introduced by Deng et al grafting maleic anhydride [20] and styrene [21] onto low-density poly(ethylene) films. Later, this was extended for other monomers and many other substrates including ultra-nanocrystalline diamond, graphene and silicon carbide [22][23][24][25][26][27][28][29][30]. Even bottle-brush brushes could be prepared via SIPGP on various substrates for different applications [31][32][33].…”

Additive manufacturing or 3D printing as an umbrella term for various materials processing methods has distinct advantages over many other processing methods, including the ability to generate highly complex shapes and designs. However, the performance of any produced part not only depends on the material used and its shape, but is also critically dependent on its surface properties. Important features, such as wetting or fouling, critically depend mainly on the immediate surface energy. To gain control over the surface chemistry post-processing modifications are generally necessary, since it′s not a feature of additive manufacturing. Here, we report on the use of initiator and catalyst-free photografting and photopolymerization for the hydrophilic modification of microfiber scaffolds obtained from hydrophobic medical-grade poly(ε-caprolactone) via melt-electrowriting. Contact angle measurements and Raman spectroscopy confirms the formation of a more hydrophilic coating of poly(2-hydroxyethyl methacrylate). Apart from surface modification, we also observe bulk polymerization, which is expected for this method, and currently limits the controllability of this procedure.

A novel PTA/ZIF‐8@CA composite material (PTA = phosphotungstic acid; CA = cellulose aerogel) with multilayer three‐dimensional network structure was synthesized with cellulose aerogel as the framework and MOFs as the filler. The results showed that the degradation rates of methylene blue at δ = 10 ppm reached 99.8 % respectively in 30 min under the conditions of PTA/ZIF‐8@CA input amount of 0.6 g·L–1 and pH = 5. The degradation rate of rhodamine B at δ = 10 ppm reached 99.7 % in 60 min. This shows that PTA/ZIF‐8@CA has excellent degradation efficiency and short‐term performance. In addition, after 5 photocatalytic cycles, the degradation rates of methylene blue and rhodamine B by PTA/ZIF‐8@CA were still 83.0 % and 82.5 %, respectively, reflecting that PTA/ZIF‐8@CA has terrific photocatalysis stability.
