Toughening epoxies with halloysite nanotubes

open access: yesPolymer, 2008
An experimental attempt was made to characterize the fracture behaviour of epoxies modified by halloysite nanotubes and to investigate toughening mechanisms with nanoparticles other than carbon nanotubes (CNTs) and montmorillonite particles (MMTs ...

The Clay Minerals Halloysite and Meta-Halloysite

Nature, 1946
X-RAY studies of these minerals in relation to (a) their reactions with organic liquids (MacEwan), (b) the effect of heat treatment (G. W. B. and K. R.) have led us to certain conclusions which can best be expressed in a joint communication. Meta-halloysite has the same formula as kaolinite, Al2Si2O5(OH)4, and from the work of Hendricks and others1 is ...

Behavior of halloysite clay under formamide treatment

open access: yesApplied Clay Science, 2007
Halloysite clay minerals are ubiquitous in soils and weathered rocks where they occur in a variety of particle shapes and hydration states. When both halloysite and kaolinite are present in a given sample, differentiation between the two minerals is ...

Dielectric properties of halloysite and halloysite-formamide intercalate

Journal of Applied Physics, 2014
Due to a high increase in electromagnetic pollution, the protection from non-ionizing electromagnetic radiation (EMR) represents an important problem of contemporary environmental science. We are searching for natural materials with the potential for EMR screening.
