摘要：Degradable filters are disclosed, as well as methods of making them, thatinclude the steps of applying a plasticizer containing a photoactive agent to celluloseester fibers to obtain plasticized cellulose ester fibers; and forming the plasticizedcellulose ester fibers into a filter. The cellulose ester fibers may comprise celluloseacetate, the plasticizer may be triacetin, and the photoactive agent may include a numberof types of titanium dioxide, for example mixed phase titanium dioxide particles. Thefilters are useful, for example, in preparing cigarette filters.
