Magnet Made From Plastics
>> Saturday, August 29, 2009
Research the use of plastics to replace metal materials become known especially since the discovery of electrically conducting plastic, which then delivers Prof. Shirakawa won the Nobel prize in chemistry in 2000. Another study is the possibility of electrolyte and the plastic becomes a magnet. From England reported the discovery of a plastic magnet, as reported by New Scientist magazine.
British scientists have developed the first plastic magnet at £ äunia. Breakthrough will greatly benefit in arithmetic and medicine.
In the past, the magnet is always made of metal material. Then in 2001, a team of chemical scientists United States (U.S.) from the University of Nebraska-Lincoln (UNL) shows the possibility to make plastic magnets.
However, plastic magnets they make, and plastic magnets made after other still has many weaknesses. The magnet is only working at a very low temperature, so not suitable for everyday products.
Latest plastic magnet developed by the University of Durham (UD) using organic materials is elektroaktif first magnet working at room temperature.
As early tests, scientists used to take pieces of iron placed on the laboratory bench.
The magnet is a polymer-a-molecule circuits made using two components, called Pani and TCNQ, and have the materials mengadung unusual electricity.
Typically, the magnetic properties of electrons generated by the parallel spin. In plastic materials, which is almost the same effect obtained by align-patikel deliberately pertikel electrified called free radicals.
At first, these plastic materials showed only few signs of a magnet.
After three months of failure, the researchers had to give up, until they decided to test the final polymer sample.
They feel surprised to find these plastics have developed into a magnet, as reported in New Scientist magazine.
Although the magnetic effects produced weaker when compared with the magnetic material made of metal, but the researchers feel confident if the plastic material can be developed into a magnet.
"The reaction of polymer has not reached 100% and the magnetic force vary depending on the materials used. As we increase the efficiency, the total strength would be increased ", said Naveed Zaidi, chairman of the research team.
Plastic magnet is a material commonly used to cover computer hardware, and can be used to increase disk storage capacity.
