Chen, Xinwei published the artcileDesigning nanoporosity in a swollen polymer for the controlled release of a highly volatile fragrance, Product Details of C9H10O2, the main research area is nanoporosity swollen polymer highly volatile fragrance.
Controlling the fragrance release profile, especially the highly volatile top note, can prolong the desired scent of the fragrance. Here, the porosity of a swollen cross-linked polyurethane acrylate (PUA) polymer, which is tuned by the length of a modulator, can influence the evaporation rate of the top note. In particular, the evaporation rate of benzyl acetate (BA), a common top note, is reduced by a factor of 6.5 (from 134 to 17 mg m-2 min-1) when BA is released from the best-performing PUA against a reservoir of BA. The average diameter of an opening in the fragrance-loaded PUA is â? nm, as determined by the thermoporosimetry approach. Such a pore size can effectively control the evaporation rate of BA, as predicted by the theor. model, which reveals that a pore diameter of <16 nm is required. Computational modeling reveals the optimal chain length for a modulator used for the sustained released of fragrance, confirming the exptl. data. Finally, BA continues to be released from the PUA matrix for a prolonged period, even after 3 mo, whereas the same quantity of BA would completely evaporate after 1 wk in the absence of PUA matrix. Approx. 50wt% of BA remains after 60 days, making it one of the best techniques in sustaining the release of a top note.
