A ratio between the organic and aqueous phase is 1:9-9:1, preferably 1.5-5. The particles have a diameter of 100-2 mu m, preferably 250-450 nm. Thermotropic circuit of the particle reversibly extends in a temperature of 25-80 degrees C. The amount of the thermotropic particles in the polymer matrix is 0.2-48 wt.%, preferably 3-25 wt.%. The polymer matrix is a paint, coating, resin, thermosetting or thermoplastic, and contains at least two thermotropic particles with different switching temperature. EXAMPLE - The aqueous phase and organic phase were treated with Ultra-Turrax 3 (RTM: High-performance dispersing machine) at 17000 revolutions per minute. The mixture was transferred to a flask and heated to 50-80 degrees C for 30 minutes with stirring. The flask was purged with nitrogen and equipped with a reflux condenser. After 15 minutes, sodium peroxide sulfate initiator solution was added. The reaction mixture was heated to 90 degrees C and then cooled to 80 degrees C for 70 minutes. Mixture of octadecyl acrylate and methyl methacrylate was added in dropwise to the reaction mixture and heated to 80 degrees C for 85 minutes until the reaction was completed. The solution was cooled to room temperature and allowed to stand for overnight. The suspension was filtered to obtain thermotropic particles (yield 82%).
