Highly Efficient 3D‐Printed PVDF‐Based Triboelectric Nanogenerators Featuring Polymorphic Perovskite Nanofillers

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates the use of a low‐cost 3D printing technique to prepare a large‐area PVDF‐FAPbI3 composite dielectric film for flexible TENG application. The δ→α phase transformation of the FAPbI3 nanofillers has significantly improved the β‐phase content, morphology, and dielectric properties of the PVDF film.

Solution‐Processable and Ambient‐Stable Highly Conductive p‐Type Polymers Derived from Dihydropyrazine and Ethylenedioxythiophene

open access: yesAdvanced Functional Materials, EarlyView.
This work presents π–conjugated polymers based on dihydropyrazine (DHP) and ethylenedioxythiophene (EDOT), developed to produce highly conductive, flexible films for printed electronics. By optimizing the DHP and EDOT ratio, strong and compact π–π stacking is achieved, resulting in polymer films with conductivities up to 1700 S cm−1 under ambient ...

Dynamic Networks via Polymerizable Deep Eutectic Monomers for Uniform Li+ Transport at Interfaces in Lithium Metal Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The PDEM‐based SIGPE provides a dynamic nanophase from Li+‐bridged molecular self‐association, enhancing electrochemical stability and facilitating uniform Li+ ion flux at the interface. This unique solvation structure results in a hetero species‐driven inorganic‐rich SEI and long‐term cycle stability, suggesting that a PFAS‐free Li+‐containing monomer
