The electrical charge is now found not only in the form of a metal such as batteries. Scientists are now developing innovative new eco-friendly electricity, which store electricity in the paper. How come?
Scientists in Sweden have made paper bermutan electricity. Quoted from page Sciencealert, scientists make a single sheet of material measuring 15 cm with a thickness of less than 0.5 cm. They can store electricity with a capacity of 1 Farad. This capacity is the same as supercapacitors used in electrical devices. How to make it?
The necessary ingredients such as black paper with slippery materials such as plastics, which serves as a thin film capacitor which serves as a magnetic charging, and nanocellulose and conductive polymers are used as power storage.
Charging can be done a few minutes. Paper containing an electric charge can also be folded like origami paper, so it can be made in any shape according to taste. Researchers from the Laboratory of Organic Electronics Linköping University Xavier Crispin said they produce capacitor materials in 3D. They can produce sheets thicker.
The team created a sheet by splitting cellulose fibers using high-pressure water. This fiber diameter of 20 nanometers and added into an aqueous solution containing electrically charged polymer. Polymer then forms a thin layer on top of the fiber.
"Fiber will be on the inside, where the fluid in the space between them serves as the electrolyte," said one of the team, Jesper Edberg.
According to the researchers, lightweight paper, requires no hazardous chemicals or heavy metals, and water resistance. One of the challenges of this research is to develop an industrial process for memperoduksi paper capacitors on a large scale. Such as plain paper pulp, the material must be dried to make the sheet. If the team can solve this puzzle, perhaps with the help of commercial partners, electric paper can be supercapacitors in the future.
