“…Polymer composites not only inherit a series of advantages from polymers, but also have the advantages of a reinforcing phase, which have been widely used in the flame retardant, anticorrosion and electromagnetic fields [ 23 , 24 , 25 , 26 ]. In recent years, due to the particularity of its structure, lamellar structural fillers have been increasingly applied in the field of anticorrosion.…”

As a typical brittle material, epoxy resin cannot meet its application requirements in specific fields by only considering a single toughening method. In this paper, the effects of carboxyl-terminated polybutylene adipate (CTPBA) and zinc powder on the mechanical properties, adhesion properties, thermodynamic properties and medium resistance of epoxy resin were studied. A silane coupling agent (KH-550) was used to modify zinc powder. It was found that KH-550 could significantly improve the mechanical properties and bonding properties of epoxy resin, and the modification effect of flake zinc powder (f-Zn) was significantly better than that of spherical zinc powder (s-Zn). When the addition amount of f-Zn was 5 phr, the tensile shear strength and peel strength of the composites reached a maximum value of 13.16 MPa and 0.124 kN/m, respectively, which were 15.95% and 55% higher than those without filler. The tensile strength and impact strength reached a maximum value of 43.09 MPa and 7.09 kJ/m2, respectively, which were 40.54% and 91.11% higher than those without filler. This study provides scientific support for the preparation of f-Zn-modified epoxy resin.

“…Since 2015, the NP-GLIDE technology has been widely used to functionalize epoxy and polyurethane (PU) coatings due to their excellent wear resistance, flexibility, and transparency. − Another advantage of the NP-GLIDE technology is that it can replace the fluorinated component with eco-friendly poly(dimethylsiloxane) (PDMS) with low surface energy as the dewetting agent. To further implement the concept of environmental sustainability, it is very important to use renewable bio-based resources instead of components synthesized from petroleum-based fossil resources for the preparation of NP-GLIDE polyurethane coatings .…”

Green and environment-friendly preparation are of the utmost relevance to the development of transparent antismudge coatings. To prepare a waterborne polyurethane (WPU) coating with antismudge property, it is challenging to balance the stability of dispersion and the antismudge property of coating. Herein, we prepare a transparent bio-based WPU coating grafted with a minor proportion of poly(dimethylsiloxane) (WPU-g-PDMS) using renewable castor oil, monocarbinol-terminated PDMS, hexamethylene diisocyanate trimer, and 2,2-bis(hydroxymethyl)propionic acid as raw materials. Effects of the dosage of monocarbinol-terminated PDMS, the curing temperature, and the curing time on the antismudge performance were studied. Results showed that rigorous stirring (3000 rpm) is necessary to obtain a stable WPU-g-PDMS dispersion with a storage time longer than 6 months. A high curing temperature (>160 °C) and a period of curing time (>1 h) are indispensable to obtain the excellent antismudge property because they would facilitate the grafted low-surface-tension PDMS chains to migrate from the interior to the coating surface. The facts that simulated contaminated liquids such as water, HCl solution, NaOH solution, artificial blood, and tissue fluid could slide off easily and cleanly, and marker ink lined on the coating surface could shrink, indicated that the WPU-g-PDMS coating has good antismudge properties, which could be self-compensated shortly after deterioration. Due to the high cross-linking degree caused by multifunctional polyol and isocyanate, the WPU-g-PDMS coating has high hardness and good anticorrosive performance. The antismudge functionalization and waterborne technology of bio-based polyurethane coatings proposed in this work could be a promising contribution to the green and sustainable development of functional coatings. This kind of WPU-g-PDMS coating is expected to protect and decorate electronic screens, vehicles, and buildings, especially endoscopes.

“…To mitigate these mechanical and electrical restrictions, HAp is generally coupled as a composite with metallic and metal oxide substrates of Ti, Mg, and carbon-based composites to act as a backbone of sorts in enhancing its mechanical properties 9 and in providing a point of electrical contact and conduction. Nanocomposite coatings are considered an effective strategy in the fabrication of heterogeneous materials 10,11 resulting in improvement in physico-chemical properties, [12][13][14][15][16][17][18] mitigating detrimental degradation, [19][20][21] and in enhancing its applicative aspects towards increased efficacy, [22][23][24][25] in reinforcement, [26][27][28][29] and sustainability. 30 The fabrication of these nanocomposites offers a certain degree of flexibility in their respective field of application.…”
