Influenced by bone tissue areas, right here, we report a nonswellable gradient hydrogel with adjustable mechanical properties via an easy acid-heat treatment of polyamide-based hydrogels. Both the hydrophilicity/hydrophobicity and crosslinking amount of the solution is simultaneously regulated by firmly taking benefit of the transformation of amide groups to imide teams in the hydrogel. A gradient imide framework is formed with a dense layer nearby the area of this solution
