The obtained hybrid films Qs/NPs were analyzed about structure by X-ray diffraction (XRD) in equipment LAB X-ray Difractometer 6000 Shimadzu with scanning of 5 to 75° 2θ, using a speed of 2°.min-1 and radiation CuKα (λ = 1.5418 Å), with voltage and current of 35 kV and 15 mA, respectively.
These groups are linked to the methylenes radicals of the structure Qs and they indicate that Qs is not 100% deacetylated, but also bands (C-H) are related to the methylene groups (CH2) of the silane agent.
And for the hybrid films NPs/Qs besides the charge transfer from Al3+ to O2- it may also involve the broad band to the transitions of the Qs as well as to defects present in the spinel structure of ZnAl2O4.

Nano montmorillonite (MMT) is a kind of clay with unique layered one-dimensional nano-structure, with super large specific surface area and diameter/thickness ratio of more than 200.
According to the mechanism of MMT stabilizing Pickering emulsion, MMT can adsorb at the oil water interface to form a surface film under the action of surface hydrophilicity, and can be distributed in the continuous phase to form a three-dimensional network structure to prevent the agglomeration between droplets and maintain the stability of the emulsion.
In the Pickering emulsion, with the increase of MMT addition, the distribution of MMT at the oil-water interface of emulsion increased and MMT formed a more stable solid interfacial film and three-dimensional space network structure.

In case of failure in printing, the non-formation of the samples can be attributed to the changes in the viscosity of the resin that happens when it goes back to the steady-state value which means that a restructuring to the original disorganized structure of the nanoparticles has been initiated.
Likewise, 3D printing technology has great flexibility in terms of structure design in which the application of materials can be expanded significantly in different fields [25].

Results and Discussion The AgNPs size and structure were determined via TEM examination.
The reduction in thermal conductivity with temperature can be attributed to the fact that temperature altered the original crystal structure of the materials and expose more free electrons and phonons to conduction.

From Fig. 1, it can be seen that both ramie fiber before and after chemical treatment shows some of the same peaks at 3400, 2903, 2368, 1427, 1371, and 897 cm-1, that prove the extraction of NCCs with various acid concentration does not affect the chemical structure of cellulose [7].
The patterns of Fig 2 show a semi crystalline cellulose structure which is in the amorphous phase that is influenced by lignin and hemicellulose.
Chemical pretreatment and hydrolysis do not affect the chemical structure of the samples.

Study on the Preparation and Performance of Epoxy Resin/AlOOH Nano-composite Materials Liao Haidaa,Zhang Weiping,Sun Xiaoming, Qin Jinfu,Hang Yongduo College of Chemistry and Ecology Engineering, Guangxi University for Nationalities, Nanning 530006, China alhd21c@tom.com Key words: epoxy resin; nano-scale AlOOH; direct blending method; performance of composite material Abstract: Using laboratory-made nano-scale g–AlOOH as nanophase raw material, the compounding method characterized by direct solution-blending was adopted to prepare epoxy resin/AlOOH nano-composite material; the influences of various factors, such as the dispersion characteristics of nano-scale AlOOH and its content in composite material, on mechanical and flame retardant properties of composite material were studied.
However, due to its highly cross-linked structure, epoxy resin has such weaknesses as strong internal stress, low impact strength and poor toughness, which cannot satisfy the growing requirements of the development of science and technology [1].
This fact could be interpreted as follows: AlOOH could not only be well dispersed in but also had some interaction with the substrate to form the reticular cross linked structure, which to a certain extent inhibited and obstructed both the movement and the energy transmission of polymer chain of the substrate during its heat-induced degradation, improving the compactness and continuity of carbon layer of the remnants formed after the decomposition of composite material through heating.Therefore, the heat transfer was effectively obstructed, and the solid-phase flame retardant function of preventing the ambient air from entering the combustion system and preventing the escape of micro molecular products generated by the decomposition of polymer, with the combustibility of the composite materials being satisfactorily reduced [6].
Thus the remnants formed after the decomposition through heating had loose structure and poor surface continuity with more defects, and had poor blocking effect.

Moreover, a small amount of tubular structures, such as carbon nanotubes (CNTs), could assure a mesoporous network that allows an easier diffusion of ions.
The most affirmed theory on the functionalisation of CNTs by means of PANI sustains that theπ-bonded surface of the CNTs (acting as acceptors) interacts strongly with the conjugated structure of PANI (acting as donor), especially through the quinoid ring [8].
The peaks structure conforms to that already proven in literature [3].
