Singapore scientists have learned to get superb aerogel from old tires



Scientists from the National University of Singapore were extremely upset by the fact that only 40 & nbsp;% of used tires go into processing - so they set themselves the goal of finding an alternative solution to this problem.

There was no clear plan, only the idea - to separate rubber from the material of tyres and give it a new shape.

For example, turn it into a porous base for aerogel - a cellular structure in which the cells are filled with gas.

During the experiments, scientists soaked thin tyre fragments in a mixture of "environmentally friendly" solvents and water to purify rubber from impurities.

The solution was then digested to a uniform mass, cooled to -50 & nbsp; ° C and lyophilized in a vacuum chamber for 12 hours.

The outlet produced a dense and light aerogel.

Unlike other types of aerogels, the rubber-based variant was many times stronger.

And after the coating of methoxytrimethylsilane it became also water-resistant, which immediately determined the promising field of its application - as a sorbent for oil spill elimination.

Yesterday 's garbage will help to get rid of another type of waste and pollution.

But most of all, Singapore scientists are pleased with the economic side of the invention.

The creation of a sheet of rubber aerogel with an area of 1 sq.m.

and a thickness of 1 cm takes 12-13 hours and costs $7.

The process can be easily scaled and turned into a commercially attractive business.

Especially, given the enormous reserves and cheapness of the source material.

Scientists from Nanyang University of Technology (Singapore) stated that they had come up with a breakthrough and very cheap way to process plastic garbage into something useful. But then admitted that further laboratories with their methodology were not yet selected and in practice it was not
