NONLINEAR DYNAMICS IN THE SOL-GEL PROCESS
摘要:
29Si NMR is used to measure the concentration of the various functional groups in an acid catalyzed Si(OEt)4:EtOH:H2O sol-gel systems.The corresponding rate expressions for the reactions are shown in equations(1-3).The non-linear dynamics in the sol-gel process has been discussed.The molecular structure is changeable as the reactions proceed and the diffusion of clusters is spatially constrained.These factors iead to an anomalous kinetics, The overall rate coefficients have been got from numerical solution.
