Abstract:
Controlled fragrance release at the right time, in the right place, depending on the context remains a technological challenge in the areas of psychophysiology, biochemistry and the entertainment industry. In this study, we demonstrate how bulk poly(dimethylsiloxane) (PDMS) templates may effectively take up and retain volatile organic compounds of essential orange oil in the original form without significantly shifting the scent profile. This is done depending on the sampling approach that follows a controllable and slow fragrance release maintaining a constant ratio of volatile compounds in a template-thickness, temperature and time-dependent manner. Thus, the increase in temperature up to 80 °C enhances the intensity of the fragrance release almost 13 fold without a significant shift in the chemical profile for 6 consecutive "ON/OFF" cycles. We believe that the concept demonstrated here towards fragrance storage via bulk PDMS templates can be used as a model case for the future use of scents.
