Abstract:
Articles are provided, including a substrate having a first major surface, the substrate including a nonwoven material, a woven material, or a foam. The article further includes microcapsules having an outer surface and a plasticizer encapsulated in the microcapsules, where the plurality of microcapsules is attached to the first major surface of the substrate with a polymeric material. A method of making an article is also provided, including providing a substrate having a first major surface and providing microcapsules having an outer surface and a plasticizer encapsulated in the microcapsules. The method further includes attaching the microcapsules to the first major surface of the substrate with a polymeric material, thereby forming a polymeric matrix attached to the first major surface of the substrate.
