比紙薄卻比鋼鐵硬的超級物質

Scientists have developed a super-material that is thinner than paper but ten times stronger than steel.
科學家已經發明出一種比紙還薄但比鋼還堅硬10倍的超級物質。

Developers of graphene paper, a compound based on graphite, claim it is not only lighter, stronger, harder and more flexible than steel, but also eco-friendly.
用石墨製成的化合物石墨紙的發明者稱，它不只比鋼更輕，更硬，更牢固和更靈活，而且環保。

They say it will revolutionise both the commercial and engineering industries - particularly car and aeroplane manufacturing.
他們說這將使商業和機器製造業發生徹底的改變——尤其是汽車和飛機制造業。

Lead researcher Ali Reza Ranjbartoreh said: 'No one else has used a similar production and heat testing method to find and carry out such exceptional mechanical properties for graphene paper. We are definitely well ahead of other research societies.
主要研究人員Ali Reza Ranjbartoreh說：“沒有人使用一個類似的生產和熱試驗方法查找並發現石墨紙張如此特殊的機械性能。毫無疑問我們領先於其他研究學會。”

'The exceptional mechanical properties of synthesised GP render it a promising material for commercial and engineering applications.
“這種合成石墨紙的特殊機械性能使它成爲在商業和機械應用方面一種有前景的材料。”

'Not only is it lighter, stronger, harder and more flexible than steel it is also a recyclable and sustainable manufacturable product that is eco-friendly and cost effective in its use.'
“它不只比鋼更輕，更硬，更牢固和更靈活，而且是一種環保的，可循環利用，可持續的製造產品，使用時性能價格比較高。”

To make the material, the team milled raw graphite by purifying it with chemicals to reshape it into 'nano-structured configurations' which are then processed into sheets of paper.
製造這種物質，該小組把原料石墨磨碎，用化學品淨化，把它重塑成“納米結構”，然後再把它加工成紙張。

The end product is six times lighter than steel, five to six times lower in density, two times harder and has13 times higher bending rigidity.
最後，該產品比鋼輕6倍，密度低5到6倍，更堅固2倍，抗彎剛度高13倍。
