Description
Technical field
The invention belongs to electric polypyrrole field of material technology, in particular to it is poly- that a kind of utilization rosin soap prepares water dispersible
The method of pyrroles's conducting nanoparticles.
Background technique
Polypyrrole (Polypyrrole, PPy) is a kind of important electron-conducting polymer, is current research and use
A kind of more heterocycle conjugated type conducting polymer.Polypyrrole is because it is with excellent air stability, higher electric conductivity, ring
Border nontoxicity and reversible oxidation-reduction quality, thus microelectronics, electrochemistry, in terms of with tempting application before
Scape, and especially paid attention to.
Pyrrole monomer can oxidation polymerization be rapidly polypyrrole in the presence of oxidant, but pure polypyrrole undopes it
Conductivity is poor, it is necessary to good electric conductivity can be just shown after dopant adulterates, conductivity often improves after doping
Number 103-104Times.
Rosin has many excellent physics and chemical characteristic, such as anti-corrosion, insulation, bonding, emulsification etc..In the last hundred years,
Rosin product is widely used in the fields such as coating, adhesive, ink, papermaking, rubber, food, biological products.Currently, rosin
Chemical utilization develops via the direct sharp primary product such as rosin and its mixture to deep exploitation rosin derivative direction.This hair
Dopant used in bright is rosin soap.
Summary of the invention
The object of the present invention is to provide a kind of methods for preparing water dispersible polypyrrole conducting nanoparticles using rosin soap.
Specific steps are as follows:
(1) the oxidant ammonium persulfate of 1 ~ 4 mass parts is dissolved in the deionized water of 100 ~ 200 mass parts, then plus
