Abstract
Polymeric microcapsules with paraffin core
containing magnetite nanoparticles modified by oleic acid and
functional polymeric shell were synthesized using the
technique of "extraction-coacervation" microencapsulation.
The influence of process parameters onto colloidal chemical
properties (size, dispersity index, surface porosity) of
synthesized microcapsules was studied. It was shown that the
use of heterofunctional copolymer as microcapsule shell
allows the possibility of irreversible immobilization of α-
amylase and provide its participation in the reaction of starch
catalytic decomposition.
