Abstract

A series of nanocapsules for self-healing materials were prepared by interfacial polymerization method using modified aliphatic amine (HB-1618) and urea formaldehyde resin as core material and shell material, respectively. The effect of processing conditions such as core/shell mass ratio, agitation rate and emulsifier on the properties of nanocapsules were investigated. Dispersion and surface morphology of nanocapsules were determined by optical microscope and scanning electron microscopy. The results showed that the optimum processing conditions were 0.7:1 for the core/shell mass ratio, 800 rpm for the agitation rate and 1 % for gum arabic content as the emulsifier. The results of SEM and osmosis performance evaluation showed nanocapsules were well encapsuled and the surface of the nanocapsule became rough, which is benefited for the use in the matrix materials.
