Nanocapsules with poly(methyl methacrylate e-co-methacrylamid) wall and n-dodecanol and 1-tetradecanol cores were fabricated using emulsion polymerization processes which were defined as one-stage and two-stage. The energy storage capacity of the encapsulated n-dodecanol was in the range of 155 to 159 j/g while the tetradenanol capsules could store energy in the range of 166 to 175 j/g. The wall of the capsules exposed to two-stage decomposition, and the thermal degradation temperature of the nanocapsules prepared using the two-stage process increased. It was concluded that thermal and chemical resistance of the nanocapsules could be improved slightly using two-stage emulsion polymerization method. In the study, the nanocapsules were applied to the chemically modified cotton fabrics using pad-dry-cure method. The homogeneous distribution of the nanocapsules on the fabric surface and their durability after repeated 20 times washings were confirmed by SEM images. The washing durable thermo-regulating property of the fabrics was revealed by T-history test.
