摘要

In this study, we prepared highly porous polyamide (PA) monolith in a continuous and scalable solution foaming process. The created materials, displaying a structure with both open and closed pores, had oils or organic solvents uptake capacities ranging from about 4.8 to 10.7 g/g. Moreover, they had sorption retention higher than 96% after 10 cycling tests because the structures of pores were not broken during the adsorption process. On the other hand, they absorbed oils and organic solvents rapidly and reached saturation in 30 s. A great promising way was provided to fabricate highly porous PA for the cleanup of large-scale oil or organic solvent spills. (C) 2017 Elsevier B.V. All rights reserved.
