Nanotech Clay Armour Creates Fire Resistant Hard Wearing Latex Emulsion Paints

26.07.2007
Researchers at the University of Warwick's Department of Chemistry have found a way of replacing the soap used to stabilize latex emulsion paints with nanotech sized clay armour that can create a much more hard wearing and fire resistant paint.

To date latex emulsion paints have relied on the addition of soaps or similar materials to overcome the polymer parts of the paint's aversion to water, stabilize the paint, and make it work.

The University of Warwick chemistry researchers led by Dr Stefan Bon have found a simple way to individually coat the polymer particles used in such paints with a series of nanosized Laponite clay discs. The discs effectively create an armoured layer on the individual polymer latex particles in the paint. The clay discs are 1 nanometre thick by 25 nanometres in diameter (a nanometre is one billionth of a metre).

The Lapointe clay discs can be applied using current industrial paint manufacture equipment. They not only provides an alternative to soap but can also be used to make the paint much more hard wearing and fire resistant.

The process devised by the Warwick team can be used to create highly sensitive materials for sensors. The researchers can take closely packed sample of the armoured polymers and heat it to burn away the polymer cores of the armoured particles leaving just a network of nanotech sized connected hollow spheres. This gives a very large useful surface area in a very small space which is an ideal material to use to create compact but highly sensitive sensors.

Their research is in a paper enitled "Pickering Miniemulsion Polymerization Using Laponite Clay as a Stabilizer" by Stefan A. F. Bon and Patrick J. Colver and is published as the cover article in Langmuir. The ACS Journal of Surfaces and Colloids Vol. 23, Issue 16 July 31.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
