I believe many people have never thought that "making grass blades together" can be used to make condoms. However, scientists at the University of Queensland in Australia have successfully extracted nanocellulose from natural grasses and added them to latex. Among them. As a result, this material is not only tougher than conventional latex, but also as thin as human hair. To harvest raw material thorns, the researchers also worked with indigenous residents in northwest Queensland.
After collection, the grass is broken into pulp, mixed with sodium hydroxide, and then passed through a small hole under high pressure to strip the nanocellulose in the straw pulp and leave a high tough fiber suspension.
After adding this fiber to natural latex, nanocellulose brings great toughness to ultra-thin condoms. In the traditional "burst test", it can withstand 20% more pressure than a normal condom and 40% more capacity.
Professor Darren Martin of the University of Queensland said: "After more refining and equipment process optimization, we believe that condoms can be made 30% thinner, but also pass all standard tests. Last year we have done 45 micron in the first commercial trial, and you The hair is almost the same."
In addition to increasing sensitivity, this condom can also save more manufacturing materials and thus reduce costs. Obviously, this will allow more people to choose it and help to spread the disease.
