Abstract
A self-healing system of nano/microstructures comprising a first type 1 and a second type 2 of longitudinal nano/microstructures each having an outer surface 100, each having a core 10, 11 and a polymeric first layer 20, 21 coaxially surrounding said core 10, 11 and at least one of said longitudinal nano/microstructure comprising a catalyst 101, wherein the core 10 of said first type nano/microstructures 1 comprises an epoxy resin, and the core 11 of said second type nano/microstructures 2 comprises a hardener, each of said first and second type nano/microstructures further comprise a second layer 30, 31 coaxially surrounding said first layer 20, 21 wherein the stiffness of said second layer 30, 31 is higher than the stiffness of said first layer 20, 21, and said hardener reacts with said epoxy resin when said first layer 20, 21 and second layer 30, 31 of said first and second type of nano/microstructures 1, 2 rupture upon a mechanical damage. A self-healing composite structure comprising said system is further provided. Also a method for obtainment of such nano/microstructures and system is provided.
