Therefore, disease in the population has become more common recently. In view of this, submicron Negative-Ion powders and excited materials were adopted in this research. The submicron NI powders and excited material powders were treated with a dispersing agent and a ball mill used first, then it was blended evenly into water-borne polyurethane by a planetary deaerate stirring machine, and finally the water-borne PU composite films were coated onto release paper with a coating rod. The main purpose of this work is to manufacture a permanent composite film which is able to release NIs. Such film is expected to not only release amounts of NI but also absorb smells and effectively create fresh air.

Carbonyl iron fibre with different Fe content (90%~98wt%) and diameter (200nm~l0μm) had been fabricated by adjusting fibre growth factors, such as velocity of Fe5 vapor and protective gas, temperature of chemical decomposition and magnetic field strength. So the diameter of carbonyl iron fibre could be controlled from micron to sub-micron.
