Fibrous electric charge

Bone is a natural composite comprised of type I collagen and calcium phosphate minerals, of which nanocrystalline apatite is the main component [39, 40]. Certain osteoconductive bioceramics exert an effect on bone cell attachment and growth factor binding or release, and can accelerate the treatment of bone defects [41-43]. Polymer composite scaffolds can be produced, via electrospinning, which contain a specific amount of electrical charge in order to form non-woven fibrous meshes with fibre dimensions in the nano- to microscale [44-46]. 

In addition to electrical charge, textile fibers are influenced by external conditions such as oxidation and flame. Deterioration of textiles or other materials can be caused by gradual oxidation during storage and/or exposure to light. Flame resistance is a term used to describe a material that bums slowly or is self-extinguishing after the removal of an external source of ignition. Fibrous materials can be flame resistant because of the innate properties of the fiber, the twist level of the yam, the fabric construction, the presence of flame retardants, or a combination of these factors. 

An example of such a series of transient experiments for a sample of paper without conductive additives (softwood Kraft pulp, 450 CSF, 80 g/m2 basis weight, Sample 1), is shown in Fig. 16. This series of transient currents represents the electric field dependence of charge transport associated with mobile ions within the water associated with the fibrous network of the papor. The initial transient current, labeled (a), corresponds to the first application of an electric field (E = 2.5 x 103 Volts/cm) to the new sample. After reversing the polarity of the power supply an electric field of the same magnitude is applied to the sample which leads to the transient current shown by label (b) in Fig. 16. (N.B. the scale of the ordinate is different for... 

At the same time, anions are repelled to semiconductor side and another interface of electrolyte/semiconductor with high electric capacity is achieved. The double-layer capacitor induces the charge carrier in the semiconductor. The switch rate is lower than TFT because the accumulation of carriers in the semiconductor layer comes from the migration of ions in electrolyte, which is not instantaneous. Moreover, the electrolyte is in sol—gel form whose aging is still a problem in the case of no encapsulation. However, the easy processing condition is a huge advantage for fabrication of fibrous transistors.
