Abstract

micro ou nanocápsulas com propriedades fotocatalíticas para libertação controlada de agentes difusores e método de obtenção do mesmo. a presente divulgação insere-se no domínio de produção de revestimentos funcionais para a libertação controlada de agentes voláteis. mais especificamente, consiste em cápsulas, em particular microcápsulas ou nanocápsulas funcionalizadas quimicamente com nano materiais fotocatalíticos na superfície interna ou externa da parede da cápsula, que por ação solar ou luz artificial com o mesmo espectro de radiação eletromagnética, libertam o agente difusor/agente ativo, sendo este um vapor, líquido ou sólido. a presente divulgação diz assim respeito a uma cápsula para transportar um agente ativo com propriedades fotocatalíticas, com um diâmetro externo entre 0.1-500 µm, em que a cápsula é formada por uma parede e um núcleo para alojar o agente difusor. a presente divulgação também diz respeito a um método de obtenção das cápsulas agora divulgadas. as aplicações visam a área farmacêutica, biotecnologia, engenharia civil, sanitária, agroquímica, automóvel e alimentar.
