The structure is shown in Fig.1.
Such phenomenon may be caused by the reactions initiated by plasma, and the polyvinyl alcohol was grafted on the polyester fabric, thus makes the molecular structure closer and harder to slip and the fabric become hard to snap.

The chain structure crystals are parallel in that they extend in the direction of C axis.
It may be due to the removal of hydroxyl groups from the Al-O and Si-O skeleton structures and the reorganization and orderly arrangement of the Si-O-Al-O three-dimensional network in the sample, resulting in slight weightlessness.

Nanofibers mimic the extracellular matrix structure leading to the potential use of nanofibers for tissue engineering.
The Fourier transform infrared spectrophotometer (FT-IR) (Thermo Scientific iD7 ATR, Thermo Fisher Scientific co., Ltd., Massachusetts, USA) was measured to confirmed the chemical structure of the dual-charge nanofibers.

In summary, the parcel structure in the microstructure of the sample prepared by the precipitation method is much better than that of the sample prepared by the ball milling method.
(a) (b) (c) (d) Fig.3 Morphology and structure of different powders in scanning electron microscopy (a and c-Mechanical ball milling method, b and d-Chemical precipitation method) It can be seen from Fig.4 that the surface hardness (824HV) of the cermet material prepared by the mechanical ball milling method is lower than the surface hardness (1005HV) of the cermet material prepared by the chemical precipitation method, the surface hardness refers to the ability of an object surface to resist deformation or damage.
