Scientific Research Applications

Organosilicon Chemistry and Polymer Development

Organosilicon compounds, such as methyldichlorosilane, have been explored for their reactivity and potential in forming polymers with unique properties. For example, the reaction of methyldichlorosilane with hexafluorobenzene under photochemical conditions produces derivatives used in creating oligomeric siloxanes. These siloxanes exhibit comparable thermal stability to polymers with pendant 3,3,3-trifluoropropyl groups, showing resistance to acidic and basic conditions (Birchall et al., 1971).

Surface Modification and Hydrophobic Coating

Silane coupling agents with fluorocarbon chains, prepared through hydrosilylation, have been used for surface modification of glass plates, enhancing their hydrophobicity and oxidation resistance. This application is crucial for developing materials with specific surface properties, such as water repellence and chemical stability (Yoshino et al., 1993).

Silicon Carbide Composites and Ceramics

Polysilazanes, obtained from reactions involving dichlorosilane and methyldichlorosilane, have served as precursors for silicon nitride/silicon carbide composites. These materials are notable for their absence of "free" carbon and high-temperature resilience, making them suitable for various industrial applications, including aerospace and automotive components (Hörz et al., 2005) .

Catalysis and Synthetic Chemistry

Silane compounds have been utilized as catalysts and reagents in synthetic chemistry, facilitating reactions such as hydrosilylation and electrophilic fluorination. These reactions are fundamental in creating a wide array of organofluorine compounds, which are of significant interest in pharmaceuticals, agrochemicals, and materials science (Petrov et al., 1990).

High-Temperature Proton Exchange Membranes

Modified poly(epichlorohydrin) with imidazolium and silane groups has been investigated for use as high-temperature proton exchange membranes. These membranes demonstrate promising properties for fuel cell applications, including high proton conductivity at elevated temperatures and robust mechanical strength (Yang et al., 2016).
