Scientists have invented thinner and stronger condoms

Dr. Nasim Amiralian stretches latex with nanocellulose

A group of scientists from the Australian Institute of Bioengineering and Nanotechnology at the University of Queensland presented its latest development: a new material for the manufacture of condoms . It turns out that if you use a special additive, the thickness of the latex is reduced to 45 microns without losing the strength of the product.

The secret to increasing the strength of latex is an additive made from nanocellulose; it is extracted from spiny grass Spinifex , which grows in Africa, Australia and some Asian countries.

On average, when using an additive, there is a 20% improvement in strength when stretching and a decrease in volume by 40%, said Professor Darren Martin (Darren Martin), lead author of the research. He believes that the refinement of the material will reduce the thickness of condoms by 30%, and even more.

Scientists have developed a process for extracting nanocellulose fibers from a biomaterial. To do this, chopped grass is mixed with sodium hydroxide to obtain a soft mass - the same as in the manufacture of paper. Then the nanowattle is stirred with water and impregnated with a latex solution. Cellulose strengthens rubber in the same way that steel rods strengthen concrete.

In such condoms, sensations will become more natural, while maintaining a reliable barrier between partners, scientists say.
