In the ionic conductivity of polymer valve block

The carrier is an ion in the solid polymer without solvent in a dry state, and thus is not understand from the ion
Insulating. Conductivity as carriers generally does not occur in a polymer solids rapid ion migration.
The number of ions and the mobility determined, the electrolyte in the aqueous solution easily ionized and can meet the conductive requirements
Mobility. In the solid phase polymer system design environment is similar to the liquid phase, should be able to get high from
Sub-conductivity-type polymer .1975 PV Wright found that poly (ethylene oxide) with an alkali metal salt of the composite body having first
The high ionic conductivity, resulting in a new kind of high ionic conductivity-type polymer, such polymer materials
Conducive to practical use, research is currently active. The polarity of the polymer and the inorganic salt compound with a polymer solid
Electrolyte former is lower the glass transition temperature of the polyoxyethylene polar polymer solvation, add
Alkali metal salts formed composite, the system is characterized by an alkali metal ion mobility than in the dry state
Higher, and easily made into a transparent film. The polymer solid electrolyte can be made of a thin layer having a certain mechanical strength,
And has the advantages of light weight, so the application prospects.
Light conductive polymer insulator before by the light, by the light conductor or semiconductor performance. Photoconductive poly
Compounds there are five major categories, namely linear co-reel polymer, the plane conjugated polymer side chain or the main chain containing polycyclic aromatic

The hydrocarbon polymer, the side chain or the main chain heterocyclic containing polymer and a high-molecular charge transfer complexes. Light conductive polymer
Was a photoconductive mechanism is that when the polymer is irradiated by light absorption of a light quantum, to obtain sufficient energy to excite electrons formed
Photo-generated carriers under the action of an external electric field, significant current flows through the external circuit. Such as laser light
Send the current generated is referred to as the photocurrent. Correspondingly, typically the contents of the current excitation with light called dark current.
