讲座摘要：Stretchable  electronics entails rubbery electronic materials. Polymer composites  comprising percolation networks of silver nanowires or carbon nanotubes  will be presented with high surface conductivity, high visual  transparency, and low surface roughness. The mechanical properties of  the composite electrodes are determined by the polymer matrix employed,  and can be made rigid, flexible, rubbery, self-healable, and shape  memorable. The composite electrodes have been used to demonstrate  stretchable transparent Joule heating, touch and pressure sensing,  large-strain actuation, and organic light emitting didoes and solar  cells. The current efficiencies of polymer OLEDs based on the composite  electrodes show significantly improved electroluminescent efficiency  than control devices on ITO/glass. OLEDs having a simple three-layer  structure: two composite electrodes sandwiching an emissive polymer  layer, can be stretched by up to 100% linear strain.
