In this study, layer structured porous chitosan scaffold was successfully fabricated using thermal induced phase separation method.
The scaffold had a layer structure with interconnective pores (50- 300 μm) and high porosity (>90%) using citric or acetic acid as the solvent.
They presented layer structure with interconnective pores (50-150 μm).
Summary Porous chitosan scaffold with layer structure was successfully fabricated using thermal induced phase separation method.

The structure information was further confirmed by MS spectra.
The structure and purity of DAHA were characterized by FT-IR, 1H NMR, 13C NMR and MS.

Annotation: Structural material composition determine its structure not ambiguously.
The physical and chemical nature of the linkage elements and materials of its parts act on the construction material structure and the final properties.
Without them, it is impossible use in chemistry or physics or in the technology, if it is necessary to investigate the materials or substances of their constituents.
In this case, the chemistry of the process corresponds to the method of combining the density diagrams of simple substances (elements, components, phases and chemical compounds) in elucidating the mechanism of complex compound formation from simple data.
Using this method, it can be got the fullest information about the composition and structure of the material.

Temperature is an important parameter because it affects water chemistry, microbial activity, and reaction rates [23].

X-ray diffraction analysis confirmed that the ball milling process did not destroy the crystal structure of the CuHCF active material.
This indicates that the synthesized CuHCF active material has good crystallinity with a face-centered cubic (FCC) structure.
This indicates that the crystal structure is neither destroyed, nor damaged by the ball milling process.
The XRD profiles show that the ball milling process did not destroy the crystal structure.
