Custom-designed carbosilane-based reactive surfactants for surface hydrophobization – AFM, Raman microscopy, and XPS investigations
Abstract
The novel reactive carbosilane cationic surfactant (SK) has been studied for glass surface hydrophobization by blending with oligodimethylsiloxane derivatives, comprising epoxide (EO) and amine / alkoxyl motifs (AO), and deposition using three different approaches: spray, spin, and dip coating.Our contribution comprises the synthesis and structure characterization of a novel surfactant ( 1 H NMR, FT-IR, and Raman spectroscopies), the optimization studies for the layer deposition by tuning the chosen parameters and compositions as well as the determination of contact angles and surface energies.The crucial roles of the layer composition and the deposition methodology were carefully investigated, especially in terms of the reactivity of SK with siloxane derivative and glass surface.The experiments were supported by the calculation of solubility parameters (δ) and the dispersion (δD), polar (δP), and hydrogen bonding (δH, including its splitting into donor (δHD) and acceptor (δHA) counterparts) components utilizing HSPiP software, showing the possibility of appropriate components blending.The layer structure and morphology were studied via atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS) analyses with Ar + sputtering as well as in-depth Raman microscopy.It was demonstrated that spray coating was an inappropriate method since it provided an extremely rough layer, while dip coating enabled unwanted separation of SK.The optimal method and composition included spin coating and mixing of SK with AO, enabling both the surface hydrophobization and formation of a stable, chemically attached to the glass surface layer as.
