Abstract: A method for forming microcapsules comprises the steps of: forming a core; enclosing a first, a second and a third layer of shells sequentially; wherein the microcapsules has one of the three properties of anti-ultraviolet and can endure a high temperature of 280° C.; and temperature sensitive and color changed and can endure a high temperature of 280° C., and endure a high temperature of 280° C. Furthermore, the three layers of the shells encloses the core so that the releasing speed of the material or drug therein is changeable, and the tension of the micro capsule is changed so as to adjust the size of the microcapsules to be between 0.01˜1000 Micron.
