Abstract: A negative coefficient of thermal expansion particle includes a first bilayer having a first bilayer inner layer and a first bilayer outer layer, and a second bilayer having a second bilayer inner layer and a second bilayer outer layer. The first and second bilayers are joined together along perimeters of the first and second bilayer outer layers and first and second bilayer inner layers, respectively. The first bilayer inner layer and the second bilayer inner layer are made of a first material and the first bilayer outer layer and the second bilayer outer layer are made of a second material. The first material has a greater coefficient of thermal expansion than that of the second material.
