Abstract
A cosmetic brush includes bristles made from shape memory polymer (SMP) filaments or fibers. The shape memory polymer filaments are selected to exhibit a first shape during assembly of the brush, and a second shape after exposure to an external stimulus in the form of heat or other energy. The SMP filaments are initially assembled to the base of the brush. The first shape can be straight to facilitate assembly of the fibers to the base. The second shape, after assembly and after being subjected to the external stimulus, can be any bristle shape suitable for enhancing the function of the brush, e.g., kinked, wavy or coiled. The brush may be comprised solely of SMP filaments, or may be a blend of SMP filaments and any other suitable filament (e.g., nylon, natural plant or animal fibers, etc.).
