Wet building material is a typical three-phase system consisting of solid matrix, gaseous air filling pores and liquid water present in porous structure.
These plasters are therefore better thermal insulators and can partially enhance thermal properties of whole building structures.

After that, Nano- Al2O3 and PTFE which is decentralize processed by surfactant are added into the plating solution of Ni-P chemistry composite plate.
After that, the test piece will be done the contrast test with electrofacing hard chromium layer, Ni-P chemistry plating, and ionitriding layer.
Annealed at 2000 C, it continues to have the amorphous structure and eliminates part of the stress, and therefore the corrosion rate generally remains the same.
In the process of crystal’s growing and educts’ gathering, the amorphous homogeneous structure is no longer in existence; meanwhile, its corrosion resistance decreases due to the P depletion in the matrix.

It could be attributed to the correlation between dye structure and silk fabric.
Dye structure variation with increasing pH had a negative impact on its substantivity to silk fibers.

Fig. 1 Schematic diagram of the structure of graphite oxide Experimental Raw materials.
After oxidation, due to the large amounts of oxygen functional groups exist, especially the surface hydroxyl contained in the structure of graphite, oxidation graphite can easily formed hydrogen bond with hydrogen, that is why graphite oxide has good hydrophily.

Study of Zoltan et al, Gonzalez et al [4-5], Suwanprateeb et al [6], Maiti et al [7], have revealed that the addition of a filler to polymer matrix yields in a deterioration of breaking strengths: this behavior has been attributed to weakness in the structure of these two-phase system caused by stress concentration.
This kind of problem can be reduced by physical and chemical treatments that lead to changes in the surface structure and surface energy of the composites.

Recently, studies on anion-selective electrode with anti-Hofmeister response have become important in analytical chemistry.
Structure of the target products analyzed via infrared spectrum and elemental analysis (theoretical values（w/%）are: C 57.57, N 8.40, H 5.40, O 9.59, Cu 19.04 while measured values are: C 57.65, N 8.56, H 5.24, O 9.46, Cu 19.09) was as shown in Figure 1.
