PURPOSE: Provided is a method of manufacturing a foam having microcapsules containing a phase-changing substance, aroma, a deodorant and an antibiotic to exhibit multiple functions as a phase changer, an aroma dispenser, a deodorant, and a sterilizer. CONSTITUTION: The method comprises: preparing microparticles having an average particle size of 3 to 15 .mu.m by adding 0.5 wt.% of sodium hydroxide to a mixture containing 5 wt.% of anhydrous maleic acid and 15 wt.% of distilled water and heating the resultant product at 90.degree.C, emulsifying the same using a high-speed agitator at 10,000 rpm, followed by reacting at 70.degree.C for 3 hours to yield a solution containing phase-changing microcapsules, filtering the resulting solution, and washing the same three times with distilled water; and preparing a urethane foam by mixing the phase-changing microcapsules with 10 to 80 wt.% of aromatic, deodorizing, sterilizing microcapsules, and 20 to 90 wt.% of a foamable resin, stirring the mixture at high speed and subjecting the resultant product to a foaming process.
