Although stretchable polymer-based devices with promising electrical performance have been produced through the polymer blend strategy, the interplay between the blend film microstructure and macroscopic device performance under deformation has yet to be unambiguously articulated. Here, we discuss the formation of robust semiconducting networks in blended films through a thermodynamic perspective. Thermodynamic behavior along with the linear absorption and photoluminescence measurements predict the competition between polymer phase separation and semiconductor crystallization processes during film formation. Semiconducting films comprised of different pi-conjugated semiconductors were prepared and shown to have mechanical and electronic properties similar to those of films comprised of a model P3HT and PDMS blend. These results suggest that a film’s microstructure and therefore robustness can be refined by controlling the phase separation and crystallization behavior during film solidification. Fine-tuning a film’s electrical, mechanical, and optical properties during fabrication will allow for advanced next-generation of optoelectronic devices.

坚固且可拉伸的聚合物半导体网络：从薄膜微结构到宏观器件性能

尽管通过聚合物共混策略已生产出具有可观电性能的可拉伸聚合物基器件，但是在变形下共混膜微观结构与宏观器件性能之间的相互作用尚待明确阐明。在这里，我们从热力学的角度讨论了混合膜中坚固的半导体网络的形成。热力学行为以及线性吸收和光致发光测量值可预测成膜过程中聚合物相分离和半导体结晶过程之间的竞争。制备了由不同的π共轭半导体组成的半导体膜，并显示出与由模型P3HT和PDMS共混物组成的膜相似的机械和电子性能。这些结果表明，可以通过控制膜固化过程中的相分离和结晶行为来改善膜的微观结构，从而改善鲁棒性。在制造过程中微调薄膜的电，机械和光学性能将允许先进的下一代光电设备。
