Surface modification of TiO2 nano-particles with silane coupling agent and investigation of its effect on the properties of polyurethane composite coating

Revisiting the Challenges in Fabricating Uniform Coatings with Polyfunctional Molecules on High Surface Energy Materials

“…Silane reagents in the form of Xn-Si-(R)4−n, (where; R = alkyl/organic fragment, X = halide or other reactive species; Figure 1) are examples of polyfunctional molecules bonding reaction commonly used for surface modification [12][13][14]. In addition, organofunctional silanes behave as hybrids between silica and organic materials making them one of the best choice for coupling agents [15][16][17][18][19][20][21][22][23]. Silanes, as surface modifying reagents, are known to readily chemisorb on most materials to either form entangled covalent networks, cross-linked monolayers or, in the case of silanols on hydroxylated surfaces, monolayers derived from hydrogen-bonding networks ( Figure 1).…”

Enhancement of the Mechanical Properties of Nanoparticulate Thin Coatings via Surface Modification and Cross‐Linking Additive

“…Modified particles are often used for different purposes, in general, e.g., for drug delivery [8] or photocatalytic processes [9], but also as fillers of epoxy resins [10][11][12] or for coating applications [13][14][15]. Examples for the latter show how the properties of composites can be enhanced by chemical bonding between the matrix material and the modified filler particles.…”

Mechanical properties of TiO2-filled CNT/PMMA composites

“…One of the commonly used composites is carbon-reinforced PMMA-based polymer material, since it possesses better mechanical and thermal properties [11].…”
