Introduction To meet rapid developments of contemporary technology, brittle materials machining technique has also been keeping pace in the world.
High efficiency mirror surface machining of brittle materials such as glass has become more important as these materials have become used more widely in optical and electronic devices [1].

Carbon can be produced from pyrolysis and heating process of organic materials [1].
In developing and fabricating battery, carbon-based materials are still the mainstream active components for the electrode materials in batteries due to their high surface area, high electrical conductivity, and excellent chemical stability.
One of the carbon materials that is easy to synthesize is activated charcoal.

Conclusion The sound absorption and isolation characteristics of PTFE Micro-aperture Membrane are almost the same with ordinary materials.
For example, characteristic of impedance is analogous to air, and sound absorption coefficient of Membrane is smaller than other materials, which leads to poor absorption characteristic.
