Chemistry dust depressor is one of the most effective way for coal dust control[6-8].
However, most of chemistry dust depressor contains virulent poison, thus the defect greatly limits its application in major industrial processes.
Therefore it has been recognized that developing ecological dust depressor is one of the most important challenges in green chemistry.
Carboxymethyl cellulose (CMC) is a water-soluble cellulose derivative and the structure is described as cellulose in which hydrogen atoms of hydroxyl groups on C2, C3 and C6 are partially substituted for carboxymethyl groups (CH2COONa) in the cellulose molecule, which promote water solubility.
The FTIR results show that the synthesized CMC has a semlar structure with the standard CMC.

An Experimental Study on Relationship Between (Meth)Acrylate Polymers Structure and its film Surface Wettability Yong Zhang, Xiufang Wen, Pihui Pi, Dafeng Zheng, Zhi-Qi Cai, Jiang Cheng*, Zhuo-ru Yang School of Chemistry and Chemical Engineering, South China University of Technology, Guangzhou, 510640, China *cejcheng@scut.edu.cn Keywords: (Meth)acrylate; Polymers structure; Surface wettability; Synthesis; Glass temperature Abstract.
The relationships between (meth)acrylate polymers structure and its film surface wettability were analyzed.
Polymer structure parameters as the side chain length(m) and glass temperature(Tg) are taken into account in discussing the migration of functional group to the outermost surface.
Different structures about fluorinated (meth)acrylate, such as homopolymers, random copolymers, block copolymers, graft copolymers, core-shell copolymers, have distinct influence on polymer film surface wettability[16].
However, to our best knowledge, there is little report to date on the relationships between the structure of (meth)acrylate and its coating film surface wettability.

Theory and calculation method Electronic structure calculation.
We search optimized structure of Al4Hn (n=6, 8, 10, 12) by adding two hydrogen atoms to the optimized structure of Al4Hn-2.
We could not find a stable structure for Al4H14.

This is due to the formation of a porous structure around nanotube conglomerates.
It can be seen that even a slight addition of carbon nanotubes to the polymer structure contributes to the softening of the samples.

Kongkhlang et al [4] reported the porous structured polyxymethylene (POM) nanofiber using a hexafluoroisopropanol (HFIP)-based solvent which indicated that the TIPS and vapor-induced phase separation (VIPS) were both the mechanism for the formation of porous structure.
The formation mechanism of the nano-structure was discussed.
In order to investigate the inner structure of the porous fibers, SEM image of the cross-section was photoed.

Fig.2 is the TEM image of MoS2-A3 (synthesized by hydrothermal deoxidization) microscopic structure.
It showed that MoS2 crystal structure is rhombohedral with the space group of P63/mmc.
This further proves that the microcrystal structure is consistent with the photograph of TEM.
