Thin polymer films for the filter of an air cleaner fabricated by mass-controlled layer-by-layer adsorption of polyelectrolytes

An extremely high performance of tobacco smoke filter for air cleaner was e stablished by forming thee polymer thin pms on the surface fiberglass by la yer-by-layer sequential adsorption polyelectrolytes. The mass controlled au tomatic dipping machine was used for the deposition process of the polyelec trolytes and if teas easy to optimize the adsorption characteristics of the filter to smoke. The newly developed filter showed remarkably high perform ance because if adsorbed large amount of smoke without supplying electric p ower. It was also found that the polyelectrolytes filters can be cleaned ju st by rinsing in a hot wafer at 90 degreesC. Consequently, a remarkable hig h performance of the polymer filter for air cleaner can be produced by the mass-controlled layer-by-layer adsorption method of polyelectrolytes.
