General description
Similar to montmorillonite, halloysite consists of two layers of aluminosilicate in 1:1 Al:Si ratio. Significant improvements in thermal, mechanical properties have been reported on addition of halloysite nanotubes in polymer composites.
Application
Isotactic propylene-halloysite nanocomposites.
Alloy composites by electroless/ autocatalytic deposition.
Poly(butylene terephthalate) (PBT) composites.
Zinc–halloysite nanotube (HNT) composite coatings.
Halloysite nanotube–hydroxyapatite–hyaluronic acid films.
Halloysite combined with polyamide, polypropylene, poly(ε-caprolactone) and fluroelastomers.
Its tube like morphology, high aspect ratio, and low percolation enables interesting applications as reinforcements in nanocomposites.
