Application of non-woven fabrics in the electronics industry

Why use nonwovens in electrics and electronics?

The structure of nonwovens gives strength and elasticity. Nonwovens insulating tape can therefore stand the stress applied during the wrapping process as well as that which arises from varying degrees of cable dimension and flexibility in use.

Non-woven fabrics are also used in the electronics industry, mainly including battery separators and floppy disk linings. Other smaller include cable packaging, insulation, and circuit board materials. The battery separator market is the largest market segment and is directly affected by the transfer of battery technology. Most of these are using lead-acid batteries. In the smaller rechargeable battery market, the growth rate of nickel-metal hydride batteries is that of nickel-cadmium batteries. These two types of batteries can only use separate non-woven materials, so there is a close relationship between the two growth rates. The potential use of batteries in fuel vehicles and elsewhere provides another non-woven battery separator as a market prospect.(Click to share to Facebook

The application of non-woven fabrics in the field of intelligence is also remarkable. The black phosphorus composite spinning solution is drawn, solidified, and melted into a black phosphorus micro-nano composite fiber non-woven electrode material through microfluid spinning technology, which has high conductivity, high energy density, and excellent flexible supercapacitor functions, and can be integrated Into the fabric to power wearable devices.

Microfluid spinning technology is based on the rapid prototyping of traditional wet spinning, combined with the laminar flow effect of microfluid technology to prepare micron-level fibers. It has many advantages that traditional spinning technology does not have. It is a kind of Fiber preparation technology without high voltage current, energy saving, safety and easy operation.

More specifically, microfluidic spinning technology can use the diffusion and laminar flow effects of microfluidics to control the composition and structure of the spinning solution, and prepare microstructures with adjustable structures and regular arrangements by simulating the operating functions of biological spinners. fiber. Microfluid spinning technology has the characteristics of rapid mass and heat transfer, precise control, easy parallel amplification, and highly controllable continuous production. Therefore, it is widely used in the fields of biology, medical treatment, energy, national defense and so on.

At present, the global market for smart wearable devices has an annual output value of approximately 28 billion U.S. dollars, with an annual growth rate of 10%. The research results have improved the cognition level of constructing one-dimensional nanofiber energy storage wearable materials in microfluidic confined spaces, and are expected to be widely used in wearable fields such as LEDs, smart bracelets, and flexible displays. These applications are inseparable from non-woven fabrics.

Thanks to nonwovens a water-blocking tape can be designed to be conductive or non-conducive and is impregnated with a powder which expands on contact with water. The expansion prevents water seeping along the cable.

The high porosity which can be achieved in nonwovens is an important factor, as a thermal barrier can be established by means of air trapped between fibres. Conductivity can be obtained by carbon impregnation of the porous structure.
