Thermoreversible Gelation of Aqueous Methylcellulose Solutions
The thermoreversible gelation of methylcellulose in aqueous solution has been studied by static and dynamic light scattering (DLS), small-angle neutron scattering (SANS), and rheology. At 20 °C, dilute solution light scattering establishes the molecular weight, second virial coefficient, radius of gyration, and hydrodynamic radius of the polymer. Semidilute solutions exhibit two relaxation mode...
متن کاملEquilibrium cluster formation and gelation
We study the formation and growth of equilibrium clusters in a suspension of weakly-charged colloidal particles and small non-adsorbing polymers. The effective potential is characterised by a short-range attraction and a long-range repulsion. The size, shape and local structure of the clusters are studied using three-dimensional particle microscopy. We observe a rapid growth in the mean cluster...
متن کاملEffect of D-sorbitol on the thermal gelation of methylcellulose formulations for drug delivery.
The aim of this study was to examine the effect of D-sorbitol on the gelation characteristics of methylcellulose in aqueous solution. The addition of D-sorbitol at concentrations of between 25 and 30% (w/v) to 1.0-2.0% (w/v) methylcellulose solutions reduced the gelation temperature from approximately 53 degrees Celsius to values between ambient and 37 degrees Celsius and increased the strength...
متن کاملAnalysis of Water State and Gelation of Methylcellulose Thermo-reversible Hydrogels by Thermal Analysis and NMR.
The gelation of aqueous methylcellulose (MC) solutions containing polyethylene glycol (PEG) was studied by the combination of differential scanning calorimetry (DSC) and Raman spectrometry. The gelation of MC hydrogels containing PEG occurred in two-steps. First, the gel network was formed by the hydrophobic interaction between MC and PEG at 310 - 313 K, and then, the gel network was formed bet...
متن کاملEffect of solvent state and isothermal conditions on gelation of methylcellulose hydrogels.
In this study, thermal behavior of aqueous solutions of methyl cellulose (MC) at a constant temperature of 50 degrees C was analyzed. Various samples were studied for two consecutive heating-cooling cycles. The experiments with the solutions prepared using cold de-ionized (DI) water showed that the rate of gelation was higher for higher MC concentrations. However, the rate was slower during the...
