Abstract

Revela um sistema constituído por nanopartículas do tipo casca-núcleo. onde a casca é constituída por nanopartículas de óxidos e o núcleo por polímeros e agentes químicos de proteção à radiação solar, o qual confere proteção solar em larga faixa espectral, variando desde UVA até UVB, devido a sua composição química que contém agentes de proteção fisica, nanopartículas de óxidos, e agentes de proteção química nanoencapsulado na matriz polimérica. Devido a sua escala de tamanho, composição e morfologia, as nanopartículas preparadas podem ser aplicadas em formulações cosméticas, na preparação de protetores solares, ou em qualquer outra formulação que tenha como objetivo principal a proteção contra a radiação solar.
