초록

본 연구에서는 초임계 이산화탄소를 반응 연속상으로 하여 졸-에멀전-겔 방법에 의한 신합성 공정을 통해 1-6μm의 평균 입자 크기를 갖는 페놀릭/퍼퍼랄(phenoic/력력미, P/F)겔입자를 성공적으로 제조하였다. 이때 초임계 이산화탄소내에서 P/F 용액을 분산시키는 효과적인 안정제로 사용되었다. 입자 크기와 입자 크기 분포에 미치는 영향을 알아보기 위하여 고형분자 안정제 함량비를 변화시켜 실험한 결과, P/F 입자의 평균 입자 크기는 고형분의 함량비가 증가함에 따라 증가했으나. 안정제의 함량비에 따른 변화는 크지 않았다. 또한 P/F 겔 입자의 구조 및 열 안정성은 IR 분석과 TGA를 통해 확인하였다.

Phenolic/furfural(P/F) gel microspheres were successfully produced by new supercritical CO₂-based process. CO₂-soluble poly(dimethylsiloxane)(PDMS) was used as the stabilizer in this system. Spherical morphology of the gel microspheres was confirmed by scanning electron microscopy. Particle size and particle size distribution of P/F gel microspheres can be modified by variety of the solids content and the stabilizer content. The resultant P/F gel microspheres have average particle size in the range of 1-6㎛. The structure of P/F gel microspheres was revealed by thermogravimetric analysis and IR analysis. Keywords: phenolic/furfural, gel microspheres, sol-emulsion-gel technique, particle size, supercritical CO₂.
