摘要： Described are bonding modulating coatings configured to provide an improved release profile of a volatile composition from a scent reservoir, wherein the modulating coating includes a barrier substance configured to hinder the release of the volatile composition through the modulating coating. The modulating coating also includes a hygroscopic substance that facilitates the release of the volatile composition through the modulating coating. The barrier substance and hygroscopic substance are mixed in a proportion such that the modulating coating provides a bonding action between adjacent scent reservoirs and may be formulated to maintain bonding even under the application of heat. The bonding modulating coating may then be used to bond a number of scent reservoirs together into a larger, three-dimensional matrix to provide improved scent retention and longevity. Release systems are also disclosed that may deliver low energy heat to a reservoir to modulate release of a substance from the reservoir.
