A large variety of designs are available for surgery application with invasive implantation by using several metallic materials, [1].
For this reason, the ideal osteosynthesis system should be made of resorbable materials, biodegradable after rib consolidation.
Main attention is addressed to materials that can give solutions with novel features in surgery application and clinical benefits.

Recently, organic-inorganic hybrid silica materials are being proposed as promising candidates for low-k materials [6-9].
Organic-inorganic hybrid silica materials are known as low-k materials with pores through steric hindrance due to rich alkyl groups, and the dielectric constant of the films also increases through low ionic polarization.
Results and discussion Figure 1 shows the FTIR spectra of as-deposited organic-inorganic hybrid silica materials.
