Characterization of swelling materials
Hydrogels are crosslinked macromolecular networks saturated by water solutions and they are an example of a swelling material. The behaviour of swelling materials can be described by a multi-component mixture model [1], which takes into account four components of the material: solid, liquid, cation and anion, together with their interactions. Hydrogels are very biocompatible because their chara...
متن کاملThe Swelling Pressure of Gelatin and the Mechanism of Swelling in Water and Neutral Salt Solutions
1. A method is described for measuring the swelling pressure of solid gelatin. 2. It was found that this pressure increases rapidly between 15 degrees and 37 degrees C., and that the percentage change is nearly independent of the concentration of gelatin. 3. It is suggested that this pressure is due to the osmotic pressure of a soluble constituent of the gelatin held in the network of insoluble...
متن کاملSelf-Sealing Cementitious Materials by Using Water-Swelling Rubber Particles
Water ingress into cracked concrete structures is a serious problem, as it can cause leakage and reinforcement corrosion and thus reduce functionality and safety of the structures. In this study, the application of water-swelling rubber particles for providing the cracked concrete a self-sealing function was developed. The feasibility of applying water-swelling rubber particles and the influenc...
متن کاملT H E Swelling Pressure of Gelatin and the Mechanism of Swelling in Water and Neutral Salt Solutions. By
The swelling of gelatin when placed in aqueous solution may be readily separated into three types. The swelling in acid or in alkali and the effect of neutral salts on this swelling have been shown by the work of Procter and Wilson, ~ and Loeb ~ to be due to the osmotic pressure of the ions of the electrolyte, in accordance with the Donnan equilibrium. The initial swelling of dry gelatin in wat...
متن کاملThe Swelling of Isoelectric Gelatin in Water
It has been assumed that gelatin consists of a network of an insoluble material enclosing a solution of a more soluble material. The swelling of gelatin is therefore primarily an osmotic phenomena in that the water tends to diffuse in owing to the osmotic pressure of the soluble material. This osmotic pressure is opposed by the elasticity of the insoluble constituent, and equilibrium results wh...
