The nanohybrid coating materials were synthesized using organically modified silica nanoparticles by a simple sol-gel process and ultraviolet (UV) curable acryl resin. The fabricated silica-acryl nanohybrid materials exhibited good solution processability and homogeneous dispersion without any phase separation regardless of the ratio of the mixture of the two components. The nanohybrid materials exhibited the effective photocurability under UV exposure. Because of their solution processability and high photocurability, the nanohybrid materials were readily converted into nanohybrid coating films on flexible substrates and were used for direct photo-patterning without requiring the developing process used in the photomask method. In particular, the organically modified silica nanoparticles within nanohybrid coating films made crucial roles in decreasing the curliness and increasing the mechanical hardness of flexible substrates. Moreover, the nanohybrid coating films exhibited high optical transmittance of above 90% in the visible wavelength range, and their surface roughnesses were much smoother than those of bare acryl coatings, exhibiting values of about 1 nm. On the basis of these outstanding properties, the fabricated nanohybrid materials can be used in solution-processable materials for producing optical and electro-optical coatings.
