Abstract

La présente invention concerne un matériau composite qui comporte un matériau poreux et amorphe ayant un matériau nanocristallin dans ses pores et qui s'est avéré être un agent d'absorption du rayonnement UV. Le matériau poreux est une matrice de pores qui agit comme charpente pour le matériau nanocristallin. Les particules du matériau nanocristallin sont isolées, ce qui signifie qu'elles ne sont pas connectées les unes aux autres. Dans certains modes de réalisation, le matériau nanocristallin est entièrement à l'intérieur des pores du matériau poreux. Dans certains modes de réalisation, le matériau nanocristallin peut sortir de certains ou de tous les pores du matériau poreux. Dans certains modes de réalisation, le matériau nanocristallin est un matériau d'oxyde de cérium. Dans certains modes de réalisation, la taille du nanocristallite varie de 2 à environ 100 nm sur son axe le plus long, avec un rapport d'aspect d'environ 1 à environ 1,5.
