THE EFFECT OF NANO- AND MICROPARTICLES ON PHASE SEPARATION AND THE STRUCTURE OF SEMIDILUTE BIOPOLYMER MIXTURES - Biochemistry and Biotechnology: Research and Development - page 92

form a weak network during interaction of the protein with sulfate polysaccharide, then the
presence of small fraction of the charged 3 um particles in such system lead to significant
decrease compatibility of biopolymers and increase the viscoelastic properties of the
emulsion. The effect of the presence of particles is especially significant in the case of use
hydrophobic CML/sulfonate and sulfate micro particles. The dominant mechanism
responsible for decrease thermodynamic compatibility in such system is formation of the
large charge microparticle (3 um) -SC/DSS associates in SC enriched phase that leads to
decrease their compatibility with alginate due to the effect of the excluded volume
interactions between SA and microparticle-DS+SC associates.. Hence, optimizing the sizes
and degree of hydrophobisity of particles will be possible affect on the phase separation of
biopolymer systems.
