“…Within the octahedral sheet, only two-third of the presented octahedral sites is filled with aluminium. The crystal structure of halloysites is described as 1:1 dioctahedral layer silicate 4 . The variations in the symmetry of the finishing structure of halloysites are due to the water molecules present between two consecutive layers.…”

In nanotechnology different nano materials are used like carbon nanotubes, nanofluids, nanoparticles, nanoemulsions, nanocapsules, etc. Due to their toxic effects the results of these nano materials are not considered safe for humans and for the environment as well. Halloysite nanotubules (HNTs) having low cost are naturally occurring environmental friendly nanotubules. These are distinctive and handy materials formed by face weathering of aluminosilicate minerals having definite ratio of aluminum, silicon, hydrogen, and oxygen. HNTs have high mechanical strength and modulus. Due to these properties it is ideal for various applications; remediation of ecological contaminants, these are acting as a career for the delivery of drugs and various macro molecules, storage of H 2 gas, for catalytic conversions and for the processing of hydrocarbons. These are also used in anticancer therapy, sustained delivery for certain agents, as a template or nanoreactor for biocatalyst, in personal care, cosmetics and as environment caring. They are also used in the fabrication of high quality white-ware ceramics, nanotemplates and nano scale reaction bottles. Due to easy dispersability in polymer matrix, abundant availability and biocompatibility, HNTs are also used in different epoxy (EP) composites. In this review, we have tried to recap the different aspects of halloysites nanotubes for their use in different research fields.

“…Lembrando que essas argilas são alumino-silicatos naturais [9], compostas de partículas ocas de diâmetros nanométricos e formato tubular. Por estas propriedades, as argilas podem ser utilizadas para a entrega controlada de drogas em locais específi cos do organismo [10]. Visando a ampliação da gama de aplicabilidade dos materiais citados, sintetizou-se, neste trabalho, nanocompósitos à base de dióxido de titânio e óxido de níquel sobre uma matriz de nanoargila haloisita utilizando o método dos precursores poliméricos.…”

ResumoO desenvolvimento de nanocompósitos para recobrimento de superfícies de partículas tem sido alvo de inúmeras pesquisas, devido ao fato de que novas e incomuns propriedades físicas e químicas, ausentes em tamanho macro e microscópico, são observadas nesses novos nanomateriais. Este trabalho apresenta o procedimento de preparação de nanocompósitos à base de nanoargila de haloisita nanorecoberta com TiO 2 e Ni, usando o método dos precursores poliméricos. Através dessa síntese foram obtidas partículas de tamanho médio variando entre 7 e 35 nm. Os produtos obtidos foram caracterizados por fi sissorção de N 2 a 77 K, difração de raios X, microscopia eletrônica de varredura e microscopia eletrônica de transmissão de alta ressolução. Os resultados mostram que a obtenção do nanorecobrimento é uma estratégia altamente promissora para a fabricação de novos compósitos, baseados em TiO 2 /Ni na superfície da argila, com aplicações tecnológicas. Palavras-chave: nanocompósitos, nanorecobrimento, dióxido de titânio, níquel. Abstract The development of nanocomposites for surface coating of particles have been the main focus of research in
