The experimental results show structures of tertiary amine group, imidazole ring and urethane group are found in CBPU molecular structure.
The morphology of the particle is uniform spheric structure and its size is related to the content of tertiary amine groups of CBPU.
However, -NCO is sensitive to water and it can not be applied directly to wet end chemistry of papermaking[3].
The blocked ratio has important effects on molecule structure of CBPU.
The morphology of the particle of CBPU emulsion is regular spheric structure with uniform particle size distribution.

Especially, On account of high chemical activity and unique crystal structure, ceria shows excellent characteristic as a polishing powder [7,8].
A variety of ceria preparation methods have been spaciously studied to improve ceria performance in polishing, such as precipitation [9], sol–gel [10], ball milling synthesis [11], hydrothermal [12], physical chemistry, and high energy dispersion [13].

In particular, we believe that dynamic nature of the substrates is essential in integrating these signals at the interface, and thus systematic studies on designing dynamic biomaterials using a supramolecular structure of molecularly movable polyrotaxane backbones have been extensively performed [4,5].
Synthesis of azidated polyrotaxanes for controlling biological ligand density Click chemistry has been widely used as a versatile method to introduce functional molecules into polymer backbones in a controlled manner [12].
In the previous study, we demonstrated that the polyrotaxane derivatives revealed much higher mobility factor than other molecular structures including random or block copolymers due to the highly dynamic nature of threaded a-CD molecules [11].

According to the special crystal structure and the chemical characteristics of synthetic cryptomelane, it was concluded that the satisfactory results of phenol degradation could be obtained by the systematic study of phenol.
This structure is beneficial to the adsorption and catalytic oxidation.
The intensified and sharp peaks could be attributed to a tetragonal structure of cryptomelane[14] (JCPDS card No. 29-1020; a = b= 9.815，c = 2.847).
The surface structure of cryptomelane, which had abundant holes, was conducive to adsorbe phenol on its surface.
