Polypyrrole

[6][3][7] Chemical oxidation of pyrrole: The process is thought to occur via the formation of the pi-radical cation C4H4NH+.

This electrophile attacks the C-2 carbon of an unoxidized molecule of pyrrole to give a dimeric cation [(C4H4NH)2]++.

[8] Most recent micro and nano droplet researches have been conducted in the synthesis of polypyrrole microstructures using various fluid templates formed on different solid surfaces.

[16] Together with other conjugated polymers such as polyaniline, poly(ethylenedioxythiophene) etc., polypyrrole has been studied as a material for "artificial muscles", a technology that offers advantages relative to traditional motor actuating elements.

[18] Polypyrrole was used in the microwave fabrication of multiwalled carbon nanotubes, a rapid method to grow CNT's.

[19] A water-resistant polyurethane sponge coated with a thin layer of polypyrrole absorbs 20 times its weight in oil and is reusable.
