HYBRID THIN FILMS APPLIED ON ANTI-REFLECTIVE TRANSPARENT COATINGS

Abstract

Based on the optical property of reflection presented by the materials and assuming applications that need to avoid such property, this work was developed through the solvotermal method, a combination of precursors: titanium butoxide; varying concentrations of TEOS and different organic agentes (acids BDC and BSA). The results of FTIR (1464 – 1381 cm^-1 and 1685 cm^-1) and SEM showed that it was possible to obtain nanometric metal-organic structures, with both BDC and BSA, it also shows that the presence of TEOS implies a reduction in the particle size obtained. The MOF's have good thermal stability and proved to be efficient thin film formers through the spin coating technique, with thicknesses below 400 nm, refractive indices less than 1.5 and light transmittance above 98%.
