Polysaccharides/Halloysite nanotubes for smart bionanocomposite materials

Carbohydrate Polymers, 2020
Biopolymers as alternative to fossils-derived polymers are attracting the interest of researcher in material science. Besides the economic advantages, the sustainability makes polysaccharides ideal candidates to prepare films and formulations.

Halloysite -A critical assessment

, 1990
Water enters the interlayer space in halloysite to minimize cation-cation Coulomb repulsion between adjacent layer surfaces and to coordinate exchangeable cations postulated as present to compensate for Al(IV). The layers roll into tubes due to lateral misfit between a larger tetrahedral sheet and a smaller octahedral sheet. Tetrahedral rotation, which

Adsorption kinetics of halloysite nanotube and modified halloysite at the Palm oil-water interface and Pickering emulsion stabilized by halloysite nanotube and modified halloysite nanotube

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2019
Abstract In this study, the interfacial tension behavior of halloysite nanotube (HNT) as a hydrophilic nanoparticle and modified APTES-HNT as a hydrophobic nanoparticle at the palm oil-water interface was investigated. The result of this study was used to determine the stability and potential formation of Pickering emulsion as a novel dispersed ...

Characterisation of Halloysite by Spectroscopy

2016
This chapter provides an overview of results obtained by a variety of spectroscopic techniques. The most common techniques employed are infrared (IR) and Raman spectroscopy, which enable detailed observation of the behaviour of water and OH-groups and the type of H-bonds formed.

Structure of prismatic halloysite

American Mineralogist, 2013
The crystal structure of halloysite, despite being one of the most commonly occurring clay minerals on the Earth’s surface, remains elusive. This paper reports on a multi-methodological study to shed more light on the atomic arrangement of halloysite from Olkhon Island, Lake Baikal, Russia, which has a prismatic morphology.

Nanocomposites of halloysite and polylactide

Applied Clay Science, 2013
Abstract Naturally occurred halloysite (Hal) nanotubes compounded with polylactide (PLA) via melt mixing formed biodegradable and biocompatible clay polymer nanocomposites (CPN). The hydrogen bonding interactions between Hal and PLA were confirmed by Fourier transform infrared spectroscopy (FTIR).

Fabrication of halloysite@polypyrrole composite particles and polypyrrole nanotubes on halloysite templates

Journal of Applied Polymer Science, 2012
AbstractHalloysites (HNTs) core‐polypyrrole(PPy) shell composite particles were fabricated by in situ oxidative polymerization of the pyrrole monomer absorbed HNTs nanotubes, obtained by the dispersion of HNTs in acid aqueous solution of pyrrole with ultrasonic irradiation and magnetic stirring, by using ammonium persulfate as oxidant.

Halloysite and Gibbsite Formation in Hawaii

Clays and clay minerals (National Conference on Clays and Clay Minerals), 1960
AbstractDesilication and removal of bases from the basalitic rocks of the Hawaiian Islands produces large amounts of halloysite and gibbsite, together with variable quantities of allophane and nontronite, iron and titanium oxides, and amorphous mineral and gel material.The nature and relative abundance of intermediate and end products of weathering ...
