Super Nano-Paper Stronger than Iron

Science and nanotechnology never fails to amaze me. From New Scientist comes news that scientists have created nano-paper which is almost as strong as steel. Similarly to normal paper, it’s made from celluose.

Celluose nanofibres are the main structural reinforcement material in plant structures. Normally, paper is made through a mechanical process which damages these fibres, reducing the strength of the paper. The new method of producing paper involves breaking down the pulp with enzymes and fragmenting them with a mechanical beater. When water is drained away, the fibres join together through hydrogen bonds giving “nano-paper”.

According to New Scientist:

Mechanical testing shows it has a tensile strength of 214 megapascals, making it stronger than cast iron (130 MPa) and almost as strong as structural steel (250 MPa). Normal paper has a tensile strength less than 1 MPa.

Wow. I wonder what novel uses could come from this.
