Development and Application of Superionic Mesoscopic Composites

(1)将α-Agl冻结在超离子导电玻璃中的新复合材料在室温下表现出极高的离子电导率，约为10^<-2>- 10^<-1>Scm^2<-1>。(2)采用DSC等温和非等温方法研究了Agl基银硼酸盐玻璃中α-Agl晶体的成核和生长动力学。(3)采用溶胶-凝胶法制备了含HCl O_4、WPA、H_2SO_4、H_3PO_4的复合硅胶。用上述酸掺杂的硅胶的电导率范围为10^<-4>-10 ^<-1>Scm^2<-1>。(4)在以HCl O_4掺杂的硅胶膜为固体电解质的EC电池中，当施加直流电压时，观察到显著的着色。(5)在酸掺杂的硅胶结构中可能形成质子的传导路径，并且传导路径与硅醇基团之间的相互作用将影响电导率。较小的相互作用可能导致掺杂硅胶膜具有较高的质子导电性。

(1) New composite materials in which alpha-Agl was frozen in the superionic conducting glasses exhibited extremely high ion conductivities of about 10^<-2> - 10^<-1> Scm^<-1> at room temperature.(2) Kinetics for nucleation and growth of alpha-Agl crystals in Agl-based silver orthoborate glasses were studied by isothermal and nonisothermal measurmentsby DSC.A constant number of nuclei of alpha-Agl precipitated in a glass matrix grew three-dimensionally.(3) Composite silica gels containing HC10_4, WPA,H_2SO_4, or H_3PO_4 were prepared by the sol-gel method. The conductivities of the silica gels doped with the acid above ranged 10^<-4>-10^<-1> Scm^<-1>.(4) In the EC cell using HC10_4-doped silica gel film as a solid electrolyte remarkable coloration was observed when d.c. voltage was applied.(5) A conduction path of proton may be formed in the acid-doped silica gel structure and the interaction between the conduction paths and the silanol groups would affect the conductivities. The smaller interaction probably reslults in the higher proton conduction of the doped silica gel films.
