In this report, a nonwoven polyethylene sheet was functionalized with a designed alginate film that can alter the odor properties, in response to the surrounding conditions, from good fragrance such as geraniol to stimulating smell like gaseous acetic acid. As-prepared sheets act as a sensor to provide an alert signal, in the case of acetic acid being generated in response to acid. This intelligent alginate polymer film composed of sodium alginate (Na-Alg), geraniol and sodium acetic acid (CH3COONa) was prepared directly on the nonwoven polyethylene sheet. Optimal conditions for the alginate film preparation were 0.75% or 1.0% Na-Alg solution containing 10%(w/v) CH3COONa. Acetic acid(approximately 3.58 ppm) could be released from the sheet on which 0.3 ml of 1.0 M hydrochloric acid was dropped. We successfully prepared a functional sheet, which can drastically change the odor properties from geraniol to gaseous acetic acid in response to acid.
