Resumo

Altos porcentajes de humedad o el contacto con el agua son las mayors causas de deterioro de los materiales celulósicos, como papel y tejidos. El objetivo principal de esta investigación es el desarrollo de film protectores en función de dos productos comerciales hidrófugos: un fluoruro de copolímero acrílico y un polidimetilsiloxano con la adición de nano-sílice. La finalidad es verificar la aplicabilidad sobre papeles y tejidos tanto antiguos como contemporáneos. Se han utilizado distintas técnicas analíticas: espectrofotómetro de infrarrojo FTIR con ATR, análisis colorimétrico, observación con microscopía óptica y electrónica, medida del ángulo de contacto y de la resistencia mecánica. Los productos se han aplicado por medio de spray o inmersión con adecuada sistematización del método y elección de disolventes a bajatoxicidad. Los resultados demuestran una buena compatibilidad y eficiencia de los productos fluoroacrilicos a bajo porcentaje de nano-sílice de inmersión.
