University of Arkansas researchers have created fibrous nanomaterial for fabricating robust, paper-like materials and devices.
This two-dimensional ""paper"" can be shaped into three-dimensional devices. It can be folded, bent and cut, or used as a filter, yet it is chemically inert, remains robust and can be heated up to 700 degrees Celsius.
""Humans have used paper made from natural fibres for thousands of years,"" said Z. Ryan Tian, assistant professor of chemistry and biochemistry in the J. William Fulbright College of Arts and Sciences. ""With this technology, we are entering a new era."" The researchers published their findings in the Journal of Physical Chemistry B.
Tian and his team used a hydrothermal heating process to create long nanowires out of titanium dioxide and from there created free-standing membranes. The resulting material is white in colour and resembles regular paper. Further, the material can be cast into different three-dimensional shapes, with different functions. The researchers have created tubes, bowls and cups using this process. These three-dimensional hollow objects can be manipulated by hand and trimmed with scissors, the researchers report.
The university has applied for patent protection on the process used to create the free-standing membranes for filtration and catalysis, and is looking for industrial partners to license and commercialize various applications of the nanopaper technology.
Hexagon Composites' subsidiary Hexagon Lincoln has been selected to supply high-pressure hydrogen tanks for the first hydrogen fuel cell vessel in the US.
The Lightweight Technologies Forum will take place in parallel to Composites Europe, on 6-8 November 2018 in Stuttgart, Germany.
Hexagon in introducing the TITAN 53, a new Mobile Pipeline gas transport module which the company says employs the largest composite cylinder tanks in the world.
