Rheological behavior of thermoreversible κ-carrageenan/nanosilica gels [PDF]
Journal of Colloid and Interface Science, 2008 The rheological behavior of silica/kappa-carrageenan nanocomposites has been investigated as a function of silica particle size and load. The addition of silica nanoparticles was observed to invariably impair the gelation process, as viewed by the reduction of gel strength and decrease of gelation and melting temperatures. This weakening effect is seen,
