Poly(p-phenylenebenzobisoxazole) (PBO) fibers possess outstanding mechanical and thermal properties among the synthetic organic fibers. Here, commercial PBO fibers have been disintegrated into uniform nanofibers with the diameter of ca. 20nm by a mixed acid treatment, and then served as a polymeric ...
Here, we demonstrate an all-in-one interfacial solar evaporator made from poly(p-phenylene benzobisoxazole) nanofiber (PBONF)/graphene oxide (GO) and PBONF/reduced graphene oxide (RGO) composite aerogels with high porosity, robust mechanical properties, and excellent thermal insulation performance. ...
