Summary: The Sol-gel method was used to prepare a Si-Ti-epoxy organic-inorganic hybrid composite sol, which was cured on the carbon steel surface to form a transparent film with excellent electrochemical protection performance and hydrophobicity. The Si-Ti-epoxy hybrid film has a denser structure, higher impedance modulus, and lower corrosion current density compared to a double-thick epoxy film.

Summary: Sol-gel technology was employed in this study to produce organic-inorganic hybrid coatings on AISI 1045 carbon steel for corrosion protection. The coatings were prepared using tetraethylorthosilicate (TEOS) and 3-(trimethoxysilyl)propyl methacrylate precursors. Thermal treatment of the coatings resulted in decreased thickness and improved scratch resistance. Electrochemical measurements showed that the coatings treated at 100 degrees C exhibited higher polarization resistance and less aggressive corrosion compared to higher temperature treatments.

Summary: Organic-inorganic hybrid emissive thin films were prepared using a sol-gel method, resulting in improved operating lifetime for the organic materials. The films encapsulate the emissive polymer in SiO2, providing a sealing effect that enhances photoluminescence lifetime. Vanadium pentoxide (V2O5) thin films were also prepared as hole-injection layers for LEDs, resulting in improved operating lifetime compared to poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS).

Summary: This study reports benzo[1,2-b:4,5-b']dithiophene polymer as an ideal organic material for preparing hybrid materials with titanium dioxide (TiO2) that exhibit enhanced photocatalytic hydrogen production under visible light. The resulting hybrid material has a reduced energy band gap of 2.9 eV and achieves a stable photocatalytic hydrogen production performance after 40 hours of cycling. The improved water splitting is attributed to faster separation of electron-hole pairs and lower recombination of photocarrier ions.

Summary: Organic-inorganic materials have advantages of both organic and inorganic resins, yet hard coating films made of organic-inorganic mixtures of resins suffer from opacity and interface peeling problems. In this study, we successfully fabricated an organic-inorganic gradient film by impeding the movement of organic and inorganic resins and enhanced the gouge hardness by sol-gel reactions of inorganic resins. The resulting organic-inorganic gradient coating exhibited excellent gouge hardness, adhesion to organic substrates, and transparency.
