Base on the study results of structural fluid mechanism and Supramolecular Chemistry, there is possibility to synthetize this polymer.
Development of the Special Gel It designed a structural fluid forming structure though interactions (called association) between polymer molecular chains.
When the residue ratio is plus, the structure of gel hasn't severe broke with some water entering the gel structure net, which don’t visually diluted.
When the residue is minus, the gel structure broke and dissolved, which is diluted.

Silver chloride (AgCl) nanoparticles with the average size of about 45 nm have successfully been doped onto the iron oxide-silica coreshell surfaces by a simple room temperature wet chemistry method under ambient atmosphere.
Synthesis of Iron Oxide-Silica Coreshell Structures.
Synthesis of AgCl-doped Iron Oxide-Silica Coreshell Structures.
This broad peak indicates that the Ag species might exist together with Fe3O4-SiO2-AgCl structures since AgCl alone cannot absorb light in the visible region [4].

This paper investigated the effect of additive on the hollow structure.
Introduction Calcium carbonate (CaCO3) particles have three crystal morphologies, which are generally classified as calcite, aragonite, and vaterite, with rhombohedral, orthorombic, and hexagonal structures, respectively [1].

The precalcined and calcined silica supported cobalt catalysts at 15, 20, and 25%Co were investigated by X-ray Absorption Spectroscopy (XAS) including the X-ray absorption near edge structure (XANES) and the extended X-ray absorption fine structure (EXAFS).
The structure of the final Co catalyst is a result of the whole preparation procedure.
It is usual to divide the spectrum into two regions; the X-ray absorption near edge structure (XANES) and the extended X-ray absorption fine structure (EXAFS).
In this paper, the study focuses on the use of X-ray Absorption Spectroscopy (XAS) as a tool to investigate the effect of calcination on the structure of silica supported cobalt catalysts.

XPS results indicate that EDM-150 oxide had a higher content of anhydrous Mn oxide and structure water, which means that it had more anhydrous characteristics as compared to EDM-65 oxide.
As current density increases above 150 mA cm-2, initially a globular structure and then a very fine-grained fibrous microstructure, randomly oriented or aligned perpendicularly to the substrate are observed[10].
The results indicate that EDM-150 oxide had a higher content of anhydrous Mn oxide and structure water, which means that it had more anhydrous characteristics as compared to EDM-65 oxide.
