Abstract:
(EN) [Problem] To develop novel nanofibers that constitute a composite electrolyte membrane and provide an electrolyte membrane which has sufficient ion conductivity (proton conductivity) and gas barrier properties even if formed into a thin membrane of 30 μm or less. [Solution] Surface-modified nanofibers which are obtained by modifying the surfaces of polymer nanofibers with an acidic substance and a basic substance, and which are characterized in that the acidic substance has proton conductivity and the basic substance increases the modification amount of the acidic substance; an electrolyte membrane which contains these nanofibers; and a method for producing a composite membrane, which comprises a step for forming a nonwoven fabric formed of polymer nanofibers, a step for subjecting the nonwoven fabric to a surface modification treatment, a step for integrating the surface-modified nanofibers and a matrix polymer by filling the pores of the nonwoven fabric with the matrix polymer, and a step for subjecting an electrolyte membrane containing the surface-modified nanofibers to a post-treatment.
(FR) [Problème] Développer de nouvelles nanofibres qui constituent une membrane d’électrolyte composite et fournir une membrane d’électrolyte qui présente des propriétés suffisantes de conductivité ionique (conductivité protonique) et de barrière aux gaz, même si elle est formée en une membrane mince de 30 µm ou moins. [Solution] La présente invention concerne des nanofibres modifiées en surface qui sont obtenues par modification des surfaces de nanofibres de polymère avec une substance acide et une substance basique, et qui sont caractérisées en ce que la substance acide présente une conductivité protonique et la substance basique augmente la quantité de modification de la substance acide ; une membrane d’électrolyte qui contient ces nanofibres ; et un procédé de production d’une membrane composite, qui comprend une étape de formation d’un tissu non tissé formé de nanofibres de polymère, une étape de soumission du tissu non tissé à un traitement de modification de surface, une étape d’intégration des nanofibres modifiées en surface et d’un polymère matriciel en remplissant les pores du tissu non tissé avec le polymère matriciel, et une étape de soumission d’une membrane d’électrolyte contenant les nanofibres modifiées en surface à un post-traitement.
