Abstract
Phenolic microsphere was synthesized by dispersion polymerization of phenol and formaldehyde with dispersant. To determine the optimal conditions for the dispersion polymerization, the influence of the following factors on the field was studied : mole ratio of formaldehyde/phenol, type of catalyst, type of dispersant and source of formaldehyde. The optimum results were obtained when the mole ratio of formaldehyde/phenol was 1.15, hexamethylenetetramine was catalyst, and arabic gum was dispersant. Carbonic microsphere was obtained by the controlled pyrolysis of phenolic microsphere. The surface structure of the phenolic and carbonic microsphere was characterized by scanning electron microscopy. Thermal properties of the phenolic microsphere were analyzed by thermogravimetric analysis.

페놀과 포름알데히드 그리고 분산제를 사용하여 미세 구형 페놀수지를 분산중합에 의해 합성하였다. 분산중합의 최적화를 결정하기 위하여 수율에 영향을 끼치는 항 즉, 포름알데히드/페놀의 몰비, 촉매의 형태, 분산제의 형태, 그리고 포름알데히드의 source의 영향을 조사한 결과 포름알데히드과 페놀의 몰비가 1.15, 촉매로 HMTA, 분산제로 아라비아 껌을 이용할 때가 분산중합의 최적 조건임을 알았다. 그리고 미세 구형 페놀수지를 열분해시켜 미세 구형 탄소입자를 합성한 후, 미세 구형 페놀수지와 미세 구형 탄소입자의 표면을 주사 전자 현미경으로 관찰한 결과 완전히 독립적인 미세 구형 탄소입자로 합성할 수가 있었다. 그리고, TGA를 이용하여 미세 구형 페놀수지의 열적 특성을 조사하였다.
