The integration of fiber materials into modern pottery creation is an attempt to explore its boundaries as a specific material and art form. Fiber materials, such as fabric and paper, are not resistant to high temperatures, and the clay attached to them can retain the surface texture, texture, and original three-dimensional form of the fiber materials intact during the kiln firing process, making up for the defects of single material molding and maintaining the visual effect of ultrathin and highly translucent works. The light source inside the work is more conducive to creating a specific artistic atmosphere. The purpose of this paper is to explore how fiber materials become the basis of ceramic works and the source of decorative expression, so that this expression and process can be systematically analyzed and interpreted in the application of ceramic art creation. Along with the rapid development of nanotechnology, electronics, and optical technology, people’s clothing fabrics have been increasing in demand in terms of function and appearance. This paper focuses on the research and development of fiber textiles from the field of science and technology and discusses the current status of fiber textiles and the possibility of combining fiber art with science and technology. In this paper, wood cellulose-multiwalled carbon nanotube/wood cellulose composite films were prepared, as well as wood cellulose films and wood cellulose/multiwalled carbon nanotube composite films. The optimal reaction time for the preparation of the films was 2 h, and the optimal reaction temperature was 70°C. Experimental results show that the dispersibility of multilayer carbon nanotubes in wood cellulose multilayer carbon nanotubes/wood cellulose composite films in wood cellulose multilayer carbon nanotubes composite films is superior. If the amount of multilayered carbon nanotubes was 3 wt%, the fracture point extension and accessibility of the wood cellulose multilayer carbon nanotubes/wood cellulose composite film are 12.2% and 106.7 MPa, respectively. It is 93.7%, respectively. 10.7% is higher than wood cellulose/multilayered carbon nanotube composite films.

The use of carbon nanotubes for piezoresistive strain sensors has acquired significant attention due to its unique electromechanical properties. In this comprehensive review paper, we discussed some important aspects of carbon nanotubes for strain sensing at both the nanoscale and macroscale. Carbon nanotubes undergo changes in their band structures when subjected to mechanical deformations. This phenomenon makes them applicable for strain sensing applications. This paper signifies the type of carbon nanotubes best suitable for piezoresistive strain sensors. The electrical resistivities of carbon nanotube thin film increase linearly with strain, making it an ideal material for a piezoresistive strain sensor. Carbon nanotube composite films, which are usually fabricated by mixing small amounts of single-walled or multiwalled carbon nanotubes with selected polymers, have shown promising characteristics of piezoresistive strain sensors. Studies also show that carbon nanotubes display a stable and predictable voltage response as a function of temperature.

Carbon Nanotube Composite

ABSTRACTHigh molecular weight polyaniline / multi-walled carbon nanotube composite films were fabricated using solution processing. Composite films with various weight percentages of multiwalled carbon nanotubes were fabricated. Physical properties of these composites were analyzed by thermogravimetric analysis, tensile testing, and scanning electron microscopy. These results indicate that the addition of multiwalled nanotubes to polyaniline significantly enhances the mechanical properties of the films. In addition, metal–semiconductor (composite) (MS) contact devices were fabricated, and it was observed that the current level in the films increased with increasing multiwalled nanotube content. Furthermore, it was observed that polyaniline containing one weight percent of carbon nanotubes appears to be the most promising composition for applications in organic electronic devices.

Zirconia Toughened Alumina

This paper reports the effects of adding carbon nanotubes on the mechanical properties of zirconia-toughened alumina thick films prepared by tape casting. Polyvinylpyrrolidone, polyvinyl alcohol, and glycerin were used as dispersant, binder, and plasticizer, respectively. The microstructure and phase content of the samples were studied using scanning electron microscopy and X-ray diffraction methods, respectively. Mechanical properties of thick composite films were investigated by microhardness and nanoindentation methods. It was determined that polyvinylpyrrolidone can be used as a dispersant for carbon nanotube, alumina, and zirconia particles; tape casting can produce thick films with homogeneous phase distribution, and that adding up to 0.01 wt.% carbon nanotube enhanced the zirconia-toughened alumina hardness by more than 30%, and fracture toughness about 40%. Increasing carbon nanotube content over 0.01 wt.% up to 0.1 wt.% increases microhardness and nanohardness but does not affect fracture toughness significantly.

Dielectric Performance

The low dielectric constant of the nonpolar polymer poly(1-butene) (PB-1) limits its application as a diaphragm element in energy storage capacitors. In this work, Ba(Zr0.2Ti0.8)O3-coated multiwalled carbon nanotubes (BZT@MWCNTs) were first prepared by using the sol–gel hydrothermal method and then modified with polydopamine (PDA) via noncovalent polymerization. Finally, PB-1 matrix composite films filled with PDA-modified BZT@MWCNTs nanoparticles were fabricated through a solution-casting method. Results indicated that the PDA-modified BZT@MWCNTs had good dispersion and binding force in the PB-1 matrix. These characteristics improved the dielectric and energy storage performances of the films. Specifically, the PDA-modified 10 vol% BZT@ 0.5 vol% MWCNTs/PB-1 composite film exhibited the best dielectric performance. At 1 kHz, the dielectric constant of this film was 25.43, which was 12.7 times that of pure PB-1 films. Moreover, its dielectric loss was 0.0077. Furthermore, under the weak electric field of 210 MV·m−1, the highest energy density of the PDA-modified 10 vol% BZT@ 0.5 vol% MWCNTs/PB-1 composite film was 4.57 J·cm−3, which was over 3.5 times that of PB-1 film (≈1.3 J·cm−3 at 388 MV·m−1).

Β Sheet

Silk films prepared from regenerated silk fibroin are normally stabilized by β-sheet formation through the use of solvents (methanol, water etc.). Herein, we report a new method of preparing water-stable films without a β-sheet conformation from regenerated silk fibroin solutions by incorporating a small amount (0.2 wt%) of multiwalled carbon nanotubes (MWCNTs). To extend the biomaterial utility of silk proteins, forming water-stable silk-based materials with enhanced mechanical properties is essential. Scanning electron microscopy and transmission electron microscopy were used to observe the morphology of the MWCNT-incorporated silk films. The wide-angle X-ray diffraction provided clear evidence of the crystallization of the silk fibroin induced by MWCNT in the composite films without any additional annealing processing. The tensile modulus and strength of the composite films were improved by 108% and 51%, respectively, by the incorporation of 0.2 wt% of MWCNTs, as compared with those of the pure silk films. The method described in this study will provide an alternative means of crystallizing silk fibroin films without using an organic solvent or blending with any other polymers, which may be important in biomedical applications.
