Abstract： Aiming at the requirements of high conductivity，mechanical flexibility and environmental toleranceof conductive polymer materials for flexible electronic devices，the conductivity retention，sensing sensitivity and selfhealing properties of multi-level porous networks，core-shell/multi-core fibers，embedded microchannels and micro-nano patterned films were evaluated under 50% cyclic stretching and 85%RH ， 85∘C wet heat aging conditions using methods such as scanning electron microscopy，electrochemical impedance spectroscopy and mechanical fatigue tests； Then，a targeted microstructure optimization strategy was proposed by using template imprinting， freeze-thaw，electrospinning， microfluidic and near-field direct writing，and pre-stretching induction techniques. After optimization，the conductivity retention of the sample after 50% stretching cycle is greater than 90% ，thesensing sensitivity reaches 2.5kPa-1 ，and the conductivity decay after wet heat aging is less than 8%
