摘要

Abstract

Intrinsically stretchable organic light-emitting diodes (is-OLEDs)

composed entirely of inherently stretchable functional layers

represent a promising enabling technology for wearable electronics due to stretching and deformation endurance during the dynamic movements of the human body. However

achieving high performance and stretchability is challenging due to limited ductility in conjugated emissive materials and the low quality of stretchable transparent electrodes (STEs). In this study

we explore an elastic-microphase-engineered emissive layer strategy for is-OLEDs. This involves investigating the effects of incorporating different styrene-butadiene-styrene block copolymer derivative elastomers into a green polyfluorene emissive polymer. The miscibility between elastomers and emissive polymers is found to be critical in regulating three-dimensional microphase separation in the blend

thus simultaneously affecting mechanical and optoelectronic properties. In addition

by pre-burying conductive polymer PH1000

the smoothed dual-embedded hybrid electrode PH1000@AgNWs@TPU (PAT) STE with superior conductivity

stretchability

and stability is achieved. As a result

the obtained is-OLED demonstrated a record luminance of 33

443 cd m

−2

and stretchability up to 120%

while also maintaining approximately 90% of its initial luminance after 100 cycles of dynamic stretching at 15% strain

representing a significant stride towards realizing the full potential of is-OLEDs for next-generation wearable electronic applications.
