Dynamic mechanical thermal analysis (DMTA) was used to determine the crosslink density and glass transition temperature of various ceramer coatings. The metal‐oxide ceramer coatings were developed using linseed oil as the organic phase with titanium isopropoxide, and zirconium propoxide as the inorganic sol‐gel precursors. The viscoelastic characteristics and tensile properties were investigated as a function of sol‐gel precursor type and content. The phase morphology, and thermal decomposition of these ceramer coatings were evaluated using small‐angle X‐ray scattering (SAXS), and thermal gravimetric analysis (TGA), respectively. The sol‐gel precursor type and content were found to effect the crosslink density, glass transition temperature, and tensile modulus. The morphology of these ceramer coatings was found to primarily depend on sol‐gel precursor concentration. TGA revealed that the thermal history of the ceramer coatings also depended on sol‐gel precursor concentration.
