Abstract
We report substantial improvement in the mechanical stability, thermal stability, and conductivity of four series of ion-conducting dispersed phase composite polymer electrolytes (CPEs). Tensile strength of filler-dispersed composite films was ≥2 MPa in contrast to ~1 MPa for undispersed polymer–salt complex. Similarly, elongation at break has shown an increase by ~200–300% in the composite films. Filler-induced enhancement in thermal and mechanical stability has clearly been noticed. The improvement in the mechanical stability is also accompanied by a corresponding increase in electrical conductivity in the composite films by 1–2 orders of magnitude at lower (2 wt.%) of the filler loading. A mechanism for the improvement in mechanical stability has been proposed. The strength of the mechanism lies in evidenced polymer–filler interaction among the composite components. Suppression of thermal degradation and increased mechanical strength of the CPEs on filler addition has been explained on the basis of transient cross-linking of the polymeric segments and filler–polymer bridging effect.
