“…In order to improve the dispersion in polymer matrix, the surface of nano ZnO can be functionalized by silane compounds [12,13]. Modification of nano ZnO surface by 3-aminopropyltriethoxysilane improved dispersion of nano ZnO particles in epoxy coating and its anti-corrosion and anti-bacterial properties.…”

In the present work, tetraglycidyl 1,4 0 -bis (4-amine-phenoxy) benzene (TGBAPB) epoxy resin has been developed using 1,4 0 -bis (4-amine-phenoxy) benzene and epichlorohydrin. The amine-functionalized nanoalumina (F-nAl) was prepared using 3-aminopropyltriethoxysilane. TGBAPB epoxy resin was further reinforced with different weight percentages (1-5 wt%) of F-nAl and were cured with 4,4 0 -diaminodiphenylmethane. Thermal and thermomechanical behavior of TGBAPB epoxy matrix and nanocomposites were studied using thermogravimetric and differential scanning calorimetric analyses. The surface morphology of epoxy nanocomposites was examined using transmission electron microscopic, scanning electron microscopic, and atomic force microscopic studies respectively.Data obtained from mechanical and thermal studies/analysis indicate that these nanocomposites could be used as highperformance materials for varied advanced industrial and engineering applications.

“…In summary, by using epoxy to modify the silicone resin offers the possibility of preparing excellent marine antifouling coatings. Some studies [12][13][14][15] also proved the possibility of combining the flexible segment structure of silicone resin with the cross-linked structure of epoxy resin. For example, Zheng et al [16] successfully prepared epoxy modified silicone through a condensation reaction using silicone intermediate and epoxy resin and cured it at room temperature using a polyamide curing agent.…”

This study addresses the issue of enhancing the mechanical properties and adhesion of silicone antifouling coatings. In this paper, γ-aminopropyltriethoxysilane was used to pretreat bisphenol A epoxy resin to obtain epoxy-silicone prepolymer, which was then mixed with hydroxyl-terminated polydimethylsiloxane to obtain epoxy-modified silicone. It was cured with polyamide curing agent and dibutyltin dilaurate catalyst to form film, and a three-component epoxy-modified silicone coating was prepared. Fourier transform infrared (FTIR) spectroscopy was used to characterize its chemical structure. The effects of epoxy content on the surface properties, mechanical properties and antibacterial properties of the coatings were characterized by confocal laser scanning microscope (CLSM), contact angle measurements, tensile test and bacterial adhesion test. The results show that adding epoxy makes the adhesion of the coating at level 1 and the surface free energy of the coating was between 15–21 mJ/m2. When its content is less than 22.1 wt %, the coating is in a ductile material state. Once it is higher than 22.1 wt %, the coating was in a brittle material state. As the content increases, material’s hardness and fracture strength increases; elastic modulus decreases first and then increases, but bacteria removal rate decreases. The modification of the epoxy to silicone can effectively improve the adhesion and mechanical properties of the coating, while maintaining the characteristics of the low surface of the coating. It plays a positive role in improving the performance of silicone antifouling coatings.
