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.

“…Therefore, PP has been a popular matrix used in association with all kinds of nanofillers such as carbon nanotubes (CNTs) [8][9][10][11][12], layered silicates (clays such as montmorillonite (MMT) etc.,) [13][14][15] and nanoparticles such as silica, graphite and calcium carbonate [16][17][18][19], even though the nanofiller dispersion is challenging in that case and often remains an issue. Halloysite nanotubes (HNTs) have recently become the subject of research attention as a new type of additive for enhancing the mechanical, thermal and fire-retardant performance of polymers [20][21][22][23][24][25][26][27][28][29][30][31][32]. Halloysite is mainly composed of aluminosilicate and has a predominantly hollow tubular structure with the chemical composition Al 2 (OH) 4 Si 2 O 5 (2H 2 O).…”

Abstract. Halloysites/polypropylene nanocomposites with different nanotubes contents were prepared by diluting a masterbatch containing 30 wt.% halloysites with polypropylene (PP). Unmodified (HNTs) and quaternary ammonium salt treated (QM-HNTs) halloysite nanotubes were used. Both degree of crystallinity and crystallization temperature increase upon addition of halloysites into PP, thus indicating a potential nucleation effect induced by the nanotubes. An homogeneous distribution and dispersion of nanotubes was observed throughout the PP matrix, with a slightly better dispersion in the case of modified QM-HNTs compared to unmodified HNTs. Mechanical tests in tension, bending and notched impact demonstrated that strength and modulus of the nanocomposites significantly increase with addition of halloysites without significant loss of ductility. An halloysite content of 6 wt.% appears as an optimum. Modified halloysites (QM-HNTs) lead to globally better performances due to strong interfacial interaction between the polymer matrix and the nanotubes.

“…of the polymers [1][2]. In determining the final performance of polymer nanocomposites the interfacial interactions and the degree of dispersion of fillers in polymer matrix are key issues [10]. Chemically, HNTs are acknowledged for their relatively lower hydroxyl density on their outer surfaces compared with fumed silica and other layered silicates such as montmorillonite [20].…”

These Halloysite is a naturally occurring aluminosilicate material (Al2Si2O5(OH)4.2H2O) with hollow tubular structure which is obtained from mines as natural deposits. Halloysite shows unique surface chemical property because of its multi-layer structure with a few hydroxyl groups present on the surface of the nanotubes. Due to the weak secondary interactions between the nanotubes by hydrogen bonds and van derWaal's forces halloysite can be easily dispersed in a non-polar polymer matrix such as polupropylene as compared to any other layer silicates. Today we know the HNT's filled polymer blends and its composites is because of various researches carried out over many years. Researchers have toiled hard to improve the thermomechanical performance and physical properties with various experiments. A looking down with hatred of different approaches, every new research shares the same objectives of getting superior thermomechanical performance and physical properties at very lower filler loadings compared to conventional polymer composites. This paper reviews the vast array of research work carried out within past decades for the modifications/intercalations of HNTs to improve the dispersion and physical properties of the nanocomposites. This study is mainly focused on the aspects related to improve the mechanical, thermal and physical properties of the nanocomposite. It reports the research trends in modification/interaction of HNTs filled polymer blends and its composites.
