In this chapter the capsaicin derivative grafting onto cellulose ispresented as an alternative to obtain bioactive papers. First, grafting of nonivamide (capsaicin derivative) onto cellulose fibers using polycarboxylicacid as linking agent is discussed. The effect of different reaction variables(namely, time, temperature, and catalyst amount), on reaction occurrenceand efficacy is analyzed. From this data, the optimal reaction conditionsare selected and then grafting reaction is applied to commercial papersheets. Final properties like antioxidant, insect repellent, and antimicrobialactivity, as well as mechanical properties of the modified paper are presented and discussed.
