Based On The Photoelectric Properties Of Inorganic Nanoparticles Doped Poly(p-phenylene Acetylene) Nanofibers

Electronic conjugated polymers have long-ranged π conjugated chains,which are superior to the common polymer in optical and electrical properties.These organic materials have the capability to be processed on a variety of substrates as well as to allow abroad tunability of emission.Compared with conventional solid materials,one dimensional(1D)semiconductor nanostructure materials exhibet special functions due to the nano effect,such as small size effect,quantum effect,surface effect and quantum tunnel effect.These unique properties emanate from that the changing of the special structure decrease the electron energy level.Electrospinning technique has been proved to be a versatile and effective method for manufacturing 1D nanomaterials,which has received special interesting by researchers.Poly(p-phenylene vinylene)with large-conjugated systems,is the most well-studied conjugated polymer due to its excellent luminescent and mechanical properties.As electroluminescent material,PPV has good flexibility,low threshold voltage,tunable band gaps,etc.The structure of PPV is multiple,because they can be designed and synthesized by different methods.In this paper,we take silver(Ag)and graphene oxide(GO)as the research objects because of their respective representativeness in the metal and nano-materials,use the physical doping,co-electrospinning technology to achieve the PPV/PVA/Ag composite nanofibers and commixture electrospinning to get the PPV/heated graphene oxide(H-GO)composite nanofibers.Using modern analysis methods for composite nanofibers and synthetic materials were characterized.This work not only enriches the study on inorganic nanoparticles(NPs)preparation methods,but also provides a good method about the study of action mechanism between inorganic NPs and the conductive polymer material.
