  6. 15. A novel chitosan-stearic coating with bee-pollen microcapsules for corrosion protection

    University essay from KTH/Materialvetenskap

    Author : Albin Andersson; [2020]
    Keywords : ;

    Abstract : In this project a novel chitosan-stearic acid (CS-SA) coating with bee-pollen microcapsules for encapsulation of 2-mecraptobenzothiazole (MBT) as a waterborne formulation for a biocompatible corrosion protection coating was developed and the coating properties was analyzed. Hydrophobic stearic acid (SA) was crosslinked with via a carbodiimide reaction to form micelles and is assembled on the bee- pollen grains and the chitosan matrix was further self-crosslinked using glutaraldehyde (GA).
