Filter with interpenetrating polymer network that biodegrades |
摘要 |
This invention relates to a filter and a method of making a filter. The filter is made of randomly orientated fibers made from an interpenetrating network formed from at least two polymers which are substantially water soluble in their salt form and which ionically interact in an aqueous solution to form the interpenetrating network. The filter is made without organic solvents, particularly, volatile organic compound, and the filter is sufficiently water soluble to biodegrade upon disposal. A desired use of the filter is a cigarette filter.
