Abstract

The synthesis of organic–inorganic hybrids is an interesting approach as it offers the possibility of combining the advantages of organic polymer (elasticity, formability) and inorganic material (hardness, strength, high chemical resistance, and thermal stability). Gelatin–siloxane hybrid materials were prepared in the reaction of gelatin and organomodified silicones containing epoxy- and both epoxy- as well as fluoroalkyl groups. The hybrids obtained were characterized using Fourier transform infrared spectroscopy, proton nuclear magnetic resonance (1H NMR) spectroscopy, and scanning electron microscopic analysis. Thermal properties of the samples were evaluated by means of thermogravimetric analysis and differential scanning calorimetric measurements, showing the influence of type and amount of organosilicon compound on thermal properties of the hybrid materials. The samples obtained with siloxane containing fluoroalkyl groups as well as with mixed siloxanes revealed higher thermal stability than unmodified gelatin. Glass transition temperatures of the hybrids occurred at lower values than for gelatin, exhibiting the plasticizing effect of the applied siloxanes. Enthalpy values of the hybrids decreased, indicating the changes in the helical structure of gelatin caused by the introduction of siloxane.
