Abstract

This paper investigates the effect of fabrication conditions of polymeric capsules, containing sunflower oil, to the morphological, geometrical, thermal and mechanical characteristics of capsules. Capsules were produced by ionotropic gelation of sodium alginate and calcium chloride, using extrusion and air-atomization methods. The results showed that the amount of oil encapsulated in capsules depends on the sodium alginate and calcium chloride concentrations. These concentration values affect the size and mechanical properties of capsules. The mechanical strength increases substantially with the supplementary treatment. The capsules showed to significantly improve the self-healing ability of bituminous mastic.
