A filler for artificial grass, and a method of preparing the filler, including a curing reaction product of a polyurethane prepolymer having isocyanate groups at both ends thereof, an aromatic diamine, and hydrophilic fumed silica, where an amount of the hydrophilic fumed silica is in a range of about 1.5 weight % to about 5 weight %, and a specific surface area of the hydrophilic fumed silica is in a range of about 200 m2/g to about 300 m2/g. The filler is environment-friendly and has high surface energy, and when water exists in its surroundings, the filler is improved in terms of containing water due to its small contact angle with respect to water. Even when a temperature of the surroundings increases, artificial grass prepared by using the filler prevent a rapid temperature increase or an abrasion or burn that may occur as a person falls down on the grass during exercise.
