The structures and the morphologies of microencapsules were characterized by FTIR, SEM, TGA and four probes technique.
As well as we know, the microencapsules have core and shell structures, and the microencapsules can be obtained easily by spray dried.
This paper was prepared the chitosan/poly lactic acid microencapsules (CS-PLA) by spray-dried method, and then synthesized the polypyrroles on the surface of CS-PLA, such biocompatible and conductive microencapsules had hollow structures and controlled conductive shell.

During recent decay, many methods such as sol-gel, wet chemistry, CVD & MOCVD, hydrothermal methods and development process have been invented for ZnO production.
Morphology of particles is more similar to hexagonal crystal structure.
The lack of a symmetry center in wurtzite structure with many mechanical band and connector cause increasing the piezoelectrics and pyroelectrics properties and its resultant is usage of ZnO in mechanical triggers and piezoelectric transducer.

In addition, the electrodes must have a good electron and oxide ion conductivity and a porous structure to get a large triple phase boundary surface area where the gases and the three species (gas molecule, oxide ions and electrons) could meet and react[3].
In addition, noble metal electrode has other disadvantages, such as formation of volatile oxides and aging of porous structures at a high temperature.

Introduction The concrete structures used many years are always carbonized by the CO2 of atmospheric environment, the carbonation changes Ca(OH)2 dissolved in pore water of concrete into CaCO3, and the concentrations of Ca 2+ and OH in pore solution are greatly reduced [1,2].
