Technical field
The present invention relates to a kind of method of rapid-assembling Ag/PPy nano compound film, be specifically related to utilize ultrasonic simplification reaction system and assemble the speed of film forming and the method for efficient at the auxiliary lower Ag/PPy of the raising Nano composite granules of centrifugal force at substrate.
Background technology
Polypyrrole (PPy) has good electroconductibility, oxidation-reduction quality, biocompatibility and environmental stability.And the Ag of nanoscale has the special optics and the catalytic performance that are determined by its shape and size.Both compound Ag/PPy nano composite materials that obtain, because synergy, physics, chemical property all make moderate progress, and huge potential using value is all being arranged aspect catalysis, biosensor, microelectronic device, the sensor.
Up to the present, had several different methods to prepare the Ag/PPy nano composite material, but large many body system is complicated, tend to add various oxygenants, reductive agent, and polyvinylpyrrolidone commonly used (PVP) is as stablizer.And ultrasonic water or some organic additives decomposition generation free radical of making can be directly as reductive agent, and product there is certain dissemination [Jin Ho Bang, Kenneth S. Suslick, Applications of Ultrasound to the Synthesis of Nanostructured Materials, Adv. Mater. 22 (2010) 1039-1059].Yet, not yet have and utilize the ultrasonic report that reaction system obtains Ag/PPy nano composite material this respect of simplifying.
The formation film is the prerequisite in the material devices process, the Ag/PPy film that utilizes the volatilization of solvent to obtain self-supporting is a kind of simple method, but, solvent evaporates is very consuming time, and the Ag/PPy film of self-supporting is frangible, bad mechanical property, and directly adding substrate, the Ag/PPy film is combined not tight with substrate.
Summary of the invention
Purpose of the present invention is intended to propose a kind of simply and effectively method of rapid-assembling Ag/PPy nano compound film, in order to effectively simplify reaction system, solve that the Ag/PPy self-supporting film is frangible, bad mechanical property, be combined the problem such as not tight with substrate and directly add substrate Ag/PPy film.The ultimate principle that the present invention is based on is: ultrasonicly make solvent (water or dimethyl formamide (DMF)) in the reaction system resolve into free radical can directly to promote AgNO as reductive agent
3And the reaction between the pyrroles, and product there is certain dissemination; Exist certain electrostatic attraction effect between Ag/PPy Nano composite granules and the substrate; can make particle assemble film forming at substrate; the booster action of centrifugal force is, particle can move along its direction has increased chance with substrate contact, thereby has improved speed and the efficient of self assembling process.
Preparation method of the present invention comprises the steps:
(1) with a certain amount of AgNO
3Be dissolved in the solvent of appropriate amount with the pyrroles;
(2) mixing solutions of (1) carried out supersound process;
(3) can place the dark place to leave standstill mentioned solution, can control dwell temperature and time of repose;
(4) step (2) or (3) gained solution are moved in the centrifuge tube, be placed with substrate in the centrifuge tube, carry out centrifugal (can control centrifuge speed, centrifugation time, centrifuging temperature), make Ag/PPy Nano composite granules rapid-assembling film forming on substrate;
(5) step (4) gained film is cleaned, then dry.
