“…Previous work with sol-gel coatings has also reported multiple time constants and these relate to water absorption in the coating as well as porosity in addition to the inhibition processes. 22,[25][26][27] Furthermore, all the coatings present a depressed semicircle in the Nyquist plot (Fig. S8, ESI †) where the sample coated with [p-O(C 6 H 13 )coum] MA based polymer has the biggest arc consistent with the largest impedance observed in the Bode plot.…”

“…In the second case, the presence of TETA in the sol–gel matrix led to the formation of interconnected epoxy-amine and silica networks, acting as a catalyst for the condensation of GPTMS and TEOS, as well as improving barrier proprieties. Moreover, considering the research works in which organic compound was employed for the preparation of industrial anticorrosive coatings, Agustín-Sáenz et al proposed the incorporation of mono-phenol (AP) and bi-phenol (BPA) organic precursors in an epoxide functionalised-silica-zirconia matrix, in order to obtain a sol–gel coating material with higher corrosion protection for zinc-coated steel [ 187 ]. In this work, sol–gel matrix containing AP and BPA showed improved corrosion protection properties owing to the formation of a highly cross-linked network due to the organic compounds, which acted as a bridge between the epoxide functions of two GPTMS molecules.…”

Nanostructured Surface Finishing and Coatings: Functional Properties and Applications

et al. 2021

View full text Add to dashboard Cite

This review presents current literature on different nanocomposite coatings and surface finishing for textiles, and in particular this study has focused on smart materials, drug-delivery systems, industrial, antifouling and nano/ultrafiltration membrane coatings. Each of these nanostructured coatings shows interesting properties for different fields of application. In this review, particular attention is paid to the synthesis and the consequent physico-chemical characteristics of each coating and, therefore, to the different parameters that influence the substrate deposition process. Several techniques used in the characterization of these surface finishing coatings were also described. In this review the sol–gel method for preparing stimuli-responsive coatings as smart sensor materials is described; polymers and nanoparticles sensitive to pH, temperature, phase, light and biomolecules are also treated; nanomaterials based on phosphorus, borates, hydroxy carbonates and silicones are used and described as flame-retardant coatings; organic/inorganic hybrid sol–gel coatings for industrial applications are illustrated; carbon nanotubes, metallic oxides and polymers are employed for nano/ultrafiltration membranes and antifouling coatings. Research institutes and industries have collaborated in the advancement of nanotechnology by optimizing conversion processes of conventional materials into coatings with new functionalities for intelligent applications.

This review presents current literature on different nanocomposites coatings and surface finishing for different substrates (such as textiles, concrete, plastics, stones, metals and so on). In particular, this study is focused on smart materials, drug delivery systems, and industrial, antifouling and nano/ultrafiltration membrane coatings. Each of these nanostructured coatings shows interesting properties for different fields of application. In this review, particular attention is paid to the synthesis and the consequent physico-chemical characteristics of each coating and, therefore, to the different parameters that influence the substrate deposition process. Several techniques used in the characterization of these surface finishing coatings are also described. In this review, the sol-gel and polymerization method for preparing stimuli-responsive coatings as smart sensor materials is described; functional polymers and nanoparticles sensitive to pH, temperature, phase, light and biomolecules are also treated. Finally, nanomaterials based on phosphorus, borates, hydroxy carbonates and silicones are used and described as flame retardant coatings; organic/inorganic hybrid sol-gel coatings for industrial applications are illustrated, together with functional nanofiller (carbon nanotubes, metallic oxides, etc.) and polymers employed for nano/ultrafiltration membrane and antifouling coatings. In the last decades, several research institutes and industries have collaborated for the advancement of nanotechnology by optimizing conversion processes of conventional materials into coatings with new functionalities for intelligent, innovative, eco-sustainable and advanced applications.
