Abstract


Polymer conductive composites have excellent mechanical performance of prefeasibility, simple teehnics and low cost, which cause great attention of the academe and have been significantly applied in numerous fields. Polypyrrole polymer materials has been applied to many fields as conductivity. This paper studies in situ polymerization with monomer intercalated legal prepared of nano-graphite flake - polypyrrole intercalative composite material can not only make the polypyrrole intercalative evenly coated in Nano-graphite flake, but also make polypyrrole intercalative particle contact more closely and the conductivity tall. But the infusibility and insolubility of this type of conductive polymers such as polyaniline and polypyrrole makes these polymer and its most complexes are powder, formability is very poor, so its’actual production application is restricted. Therefore, the current development is how to make these complexes through simple process formability and can put into a production which can solve practical problems. For the current problems, mainly from polypyrrole intercalative/graphite nano-compound material formability and maintains its electric conductivity and chemical stability after molding. Make these polymer molding can through improve experiment technology and direct molding from the modification of polyaniline and polypyrrole, and also can through less impact on conductivity of complex. The method of preparation process is more simple and excellent than the front two methods. This thesis work was research on resin as mechanical organic relative nano-graphite flake-polypyrrole intercalative conductive composite formability. The experiment is divided into three sections:Firstly, we use epoxy as the organic continuous phase of NanoGs-PPy Conductive Composite. NanoGs-PPy/epoxy composites are successfully synthesized with the method of ultrasound and grinding. And then its characterization are investigated in detail by means of such techniques as the analysis of transmission electron microscopy (TEM), scanning electron microscope (SEM), flourier transform infrared spectroscopy(FTIR), thermo gravimetric(TG) and four probe meter and vibration magnetometer. As the results shown that investment epoxy improve the mechanical properties and keep the excellent electrical conductivity.Secondly, in order to Search for more appropriate formability conditions, we are focus on the curing agent’s role in this experiment. We have been studied the influence of the type of curing agent, dosage, curing time and curing temperature. The results show that the type of curing agent, dosage and curing time have great influence on the electrical properties of this materials.Thirdly, NanoGs-PPy/ PMMA -Epoxy Consistent conductive film is successfully synthesized with the methods of grind, comeback Pulling film. And then its characterization are investigated in detail by means of such techniques as the analysis of transmission electron microscopy(TEM), scanning electron microscope(SEM), fourier transform infrared spectroscopy(FTIR), thermo gravimetric(TG) and four probe meter and vibration magnetometer. As the results shown that investment epoxy into pmma not only improves the flexibility but also keep the excellent electrical conductivity.
