Microwaveable latent polymer composites with rough surface texture

摘要

This invention relates to a latent polymer composite which contains a heat-sensitive polymer material and a microwave sensitizer. The latent polymer material is inelastic in the latent state but can be made elastic with the addition of heat. The microwave sensitizer is a solid material blended uniformly into the latent polymer composite. The sensitizer absorbs microwave radiation and heats the heat-sensitive polymer material. The polymer composite becomes elastic under microwave radiation or thermal energy. The latent polymer composite can bonded to a fibrous sheet to form a latent laminate material. When exposed to microwave radiation, the latent laminate material becomes an elastic laminate. The latent polymer composite of the laminate shrinks and returns to an elastic state creating an elastic laminate material. The polymer composite of this invention has a rough surface created by the sensitizer particles. The rough surface of the polymer filament or film provides stronger bonding to the fibrous sheets of the laminate.
