摘要

This review establishes a tripartite framework for conjugated polymer mechanics

spanning multiscale characterization

molecular and morphological engineering

and architectural innovation toward tailored functionality and bio-integrated electronics.

Abstract

Conjugated polymer thin films are key functional layers in flexible and wearable devices

where mechanical behavior directly influences device performance and stability. However

accurate mechanical characterization remains challenging due to their nanoscale thickness and brittleness. This review aims to offer a holistic view on thin-film mechanics of conjugated polymers and systematically summarizes static and dynamic mechanical characterization methods for conjugated polymer thin films

spanning bulk materials

substrate-supported ultrathin films

and freestanding ultrathin films

and elucidates the measurement principles and key features of each technique. By integrating reported experimental results

we identify multiple factors affecting thin-film mechanical behavior. Finally

an outlook is presented in which

guided by device-level mechanical requirements

the mechanical behavior of polymer optoelectronic thin films is designed and regulated through multiple strategies

and comprehensively evaluated using complementary mechanical characterization approaches

enabling subsequent optimization based on the measured mechanical response.
