One-dimensional conjugated polymer nanomaterials for flexible and stretchable electronics

Stretchable electronics will be essential components of future wearable electronics, biomedical applications, and robotics. Conjugated polymers (CPs) have good mechanical compliance and can be processed via facile solution-based methods; thus, they can be effectively adapted to flexible and stretchable electronics. In addition, the electrical and mechanical properties of CPs can be tuned to satisfy the requirements of various flexible and stretchable next-generation applications. Typically, one effective and simple approach to apply CPs to stretchable electronics is to form one-dimensional (1D) CP nanostructures. This article reviews the recent work on the development of flexible and stretchable 1D CP nanomaterials, including nanofibril networks and printed single nanowires, and their flexible and stretchable applications and then presents some perspectives for future research on 1D CP nanomaterials for flexible and stretchable electronics.
