Researchers developed intrinsically stretchable semiconducting polymers with controlled ordering for advanced electronics. This strategy enhances stretchability and mechanical reversibility while maintaining high charge carrier mobility for robust, high-performance stretchable transistors.

Area of Science:

  • Materials Science
  • Polymer Chemistry
  • Organic Electronics

Background:

  • Semiconducting polymers are crucial for stretchable electronics.
  • Achieving high mobility and mechanical reversibility in these materials under repeated stress remains a significant challenge.

Purpose of the Study:

  • To develop a universal strategy for intrinsically stretchable semiconducting polymers with controlled multi-scale ordering.
  • To improve stretchability, mechanical reversibility, and charge carrier mobility in semiconducting polymers for electronic applications.

Main Methods:

  • Incorporating two types of randomly distributed co-monomer units into polymer structures.
  • Analyzing the effects of co-monomer incorporation on polymer crystallinity, order, and mechanical properties.
  • Fabricating and testing fully stretchable transistors using the newly designed polymers.

Main Results:

  • The new polymers exhibit significantly improved stretchability and mechanical reversibility compared to regular structures.
  • High charge carrier mobility is maintained due to retained short-range ordered aggregates and crystalline microstructures under strain.
  • Stretchable transistors demonstrated the highest and most stable mobility retention over 1,000 cycles of repeated strain.

Conclusions:

  • A simple and universal molecular engineering strategy enables the development of high-mobility, intrinsically stretchable semiconducting polymers.
  • The approach is broadly applicable to various p- and n-type conjugated polymers.
  • This work provides a rapid method for creating robust semiconducting materials for next-generation stretchable electronics.
