Hydrophobic aluminum hydroxide and a method for manufacturing the same are disclosed. The hydrophobic aluminum hydroxide according to the present invention has decane adsorbed on the surface of aluminum hydroxide particles, wherein the hydrophobic aluminum hydroxide is manufactured by a method comprising the steps of: (a) introducing aluminum hydroxide particles into a decane solution comprising decane and a solvent; (b) allowing the decane to adsorb to the aluminum hydroxide particles through agitation; and (c) removing the solvent and drying the same. According to the method for manufacturing hydrophobic aluminum hydroxide according to the present invention, the surface of aluminum hydroxide can be modified to be hydrophobic. 소수성 수산화알루미늄 및 그 제조 방법에 대하여 개시한다. 본 발명에 따른 소수성 수산화알루미늄은, 수산화알루미늄 입자 표면에 데칸이 흡착되어 있으며, 이는 수산화알루미늄 입자를, 데칸과 용매를 포함하는 데칸(decane) 용액에 투입하는 단계; (b) 교반을 통해 데칸이 수산화알루미늄 입자에 흡착되도록 하는 단계; 및 (c) 용매를 제거한 후, 건조하는 단계;를 포함하는 방법으로 제조될 수 있다.
