Carbon nanotubes (CNTs) have attracted great interest because of their unique chemical structure and intriguing physical properties. [5].
The large adsorption capacity of CNTs for organic pollutant is primarily due to their pore structure and the existence of a wide spectrum of surface functional groups.

The use of newer, more ecologically friendly materials in structures has been acknowledged as critical in addressing environmental issues.
Davidovits J. created the term "geo-polymer" in 1978 after discovering that the polymerization process includes a relatively quick chemical reaction on Si-Al minerals in an alkaline environment, resulting in a 3D polymeric chain and ring structure made up of Si-O-Al-O linkages[8,19].

This influenced in particular the process of hydration and the formation of the internal structure of the material, which had negative impacts mainly on the progress of shrinkage of the AAS composite [5] and influenced the overall damage to the test specimens during compression loading (see Fig. 3).
This is most likely due to the presence of a large amount of free (unbound) water in the structure of the material which causes the damping of the signal.

From the whole plant, eight compounds, identified as luteolin, chrysoeriol, apigenin-7-methyl ether, 3, 4-dimethoxycinnamyl-D-glucopyranoside, verbascoside, cistanoside D, 2-O-b-D-glucopyranospylcucurbitacin D and arvenin I, were isolated and their structures were elucidated by comparing their physical and spectral data with those reported in the literature previously.
Their structures were shown in Figures 1~8: Conclusions.

Fig. 3 The schematic overview shows the possible chemical structures of the phenolic resins.
It has been found that the formation of amine structures takes place below temperatures of 125 °C [9,13,14].
An explanation for the higher viscosity of L1 could be the formation of more branched structures due to the presence of tri(hydroxybenzyl) amine structures.
Accordingly, their carbon matrix was analyzed with respect to its morphology and chemical structure.
