The competitive adsorption of NaCMC and SDS will lead to less reaction sites as mentioned
previously. Furthermore, permeability of TCE in microcapsules pre-pared with NaCMC and with Gum Arabic is presented in Fig. 8 to
give a comparison.It is obvious that the NaCMC-capsules are much
more stable and compact, therefore, more suitable for practical
applications. The detailed mechanism for the differences above was
not clear till now due to the complexity of interfacial phenomenon.
Taking into consideration that the stabilizers are quite different
in chemical nature, it is quite difficult to establish a general rule
relating the chemical structure of the stabilizer to physical characteristics of the microcapsules.Perhaps it attributes to different
molecular mass and chain length of stabilizers as well as different
arrangement of segments on the interface
