Gel Transition

As a kind of functional material, gelatin gel is widely used in controlled drug release, biological tissue engineering, photographic and food industries. Plenty of studies on the gelatin gel have been carried out by researchers, which include gelation mechanisms, gelation kinetics, analysis on the crosslinked structure and macroscopic performance during the gelation process. Numerical simulation is a new method used in the study of gelatin sol-gel transition process, which can make up for the deficiency of the experimental research. E.g., the dynamic gelation process makes it difficult to measure the structural and performance parameters in time and space scales in experiments. However, these problems have been solved by numerical simulation method in our previous work. The experimental, theoretical and numerical simulation research on sol-gel transition of gelatin is reviewed, and the progress and difficulties in this field are discussed.

Gel Transition

The clear and transparent sols of BaTi acetate were prepared from tetrabutyltitanate, barium acetate aqueous solution, ethanol and acetic acid. The BaTi acetate sols were transferred into gels by sol-gel process, and the gels were dried and calcined to nanostructured BaTiO3 powders. Pure barium titanate powders added in mixtures of acetone and iodine and water or acetylacetone (Acac) and ethanol (EtOH) as suspension systems, the aim of this study was to use the electrophoretic deposition technique (EPD) to fabrication the BaTiO3 ferroelectric films with high dielectric constant. During sol-gel transition process, it is found that the initial PH value of sol affected not only the sol-gel transition, but also the particles size of the final calcined BaTiO3 powders. The effects of the EPD process parameters such as the suspension, powder concentration, electrical field strength on the specific EPD deposited weight were investigated. The films sintered at 1050°C for 2h were crystallized into the tetragonal phase at room temperature, which were sufficiently dense and had uniform microstructure and excellent dielectric properties.

It is shown herein that it is possible to control the mechanical and microstructural properties of collagen gels by manipulating temperature in the vicinity of the sol–gel transition; the Fractional Maxwell Model is also shown to accurately describe the rheological behaviour of such gels.
