The biomimetic construction of a microstructural–mechanical–electrical anisotropic microenvironment adaptive to the native cardiac tissue is essential to repair myocardial infarction(MI).Inspired by the 3D anisotropic characteristic of the natural fish swim bladder(FSB),a novel flexible,anisotropic,and conductive hydrogel was developed for tissue-specific adaptation to the anisotropic structural,conductive,and mechanical features of the native cardiac extracellular *** results revealed that the originally stiff,homogeneous FSB film was tailored to a highly flexible anisotropic hydrogel,enabling its potential as a functional engineered cardiac patch(ECP).In vitro and in vivo experiments demonstrated the enhanced electrophysiological activity,maturation,elongation,and orientation of cardiomyocytes(CMs),and marked MI repair performance with reduced CM apoptosis and myocardial fibrosis,thereby promoting cell retention,myogenesis,and vascularization,as well as improving electrical *** findings offer a potential strategy for functional ECP and provides a novel strategy to bionically simulate the complex cardiac repair environment.

Enhancing the thermoelectric transport properties of conductive polymer materials has been a long-term challenge, in spite of the success seen with molecular doping strategies. However, the strong coupling between the thermopower and the electrical conductivity limits thermoelectric performance. Here, we use polaron interfacial occupied entropy engineering to break through this intercoupling for a PEDOT:PSS(poly（3,4-ethylenedioxythiophene）-poly（4-styrenesulfonate）) thin film by using photochromic diarylethene（DAE） dopants coupled with UV-light modulation. With a 10-fold enhancement of the thermopower from 13.5 μV K-1to 135.4 μV K-1and almost unchanged electrical conductivity, the DAE-doped PEDOT:PSS thin film achieved an extremely high power factor of 521.28 μW m-1K-2from an original value of 6.78 μW m-1K-2. The thermopower was positively correlated with the UV-light intensity but decreased with increasing temperature, indicating resonant coupling between the planar closed DAE molecule and PEDOT. Both the experiments and theoretical calculations consistently confirmed the formation of an interface state due to this resonant coupling. Interfacial entropy engineering of polarons could play a critical role in enhancing the thermoelectric performance of the organic film.
