Polymerized in-situ hybrid solid ion-conductive compositions

Provided herein are methods of forming solid-state ionically conductive composite materials that include particles of an inorganic phase in a matrix of an organic phase. The methods involve forming the composite materials from a precursor that is polymerized in-situ after being mixed with the particles. The polymerization occurs under applied pressure that causes particle-to-particle contact. In some embodiments, once polymerized, the applied pressure may be removed with the particles immobilized by the polymer matrix. In some implementations, the organic phase includes a cross-linked polymer network. Also provided are solid-state ionically conductive composite materials and batteries and other devices that incorporate them. In some embodiments, solid-state electrolytes including the ionically conductive solid-state composites are provided. In some embodiments, electrodes including the ionically conductive solid-state composites are provided.

Directly photo-patternable, stretchable, electrically conductive polymer

One or more embodiments relate to an electrically conductive polymer with a crosslinkable additive. The electrically conductive polymer is a directly photopatternable Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) PEDOT:PSS film with cross-linked network made of a plurality of monomers. The directly photopatternable PEDOT:PSS film PEDOT as such has a better conductivity and stretchability compared to its other counterparts. The directly photopatternable PEDOT:PSS film can further be supplemented with poly(ethylene glycol) diacrylate (PEGDA) which can help with the removal of PSS. Advantageously, the PEGDA supplemented PEDOT:PSS film can exhibit a larger charge storage capacity.
