초록

졸-겔 공정은 비교적 간단하고 사용이 편리하며 저렴한 설비투자비가 소요되면서도 우수한 물성 및 차단특성을 갖는 코팅 박막을 얻을 수 있다는 장점이 있다. 졸-겔 공정으로 코팅된 필름은 산소 등의 영향에 의해 부패되기 쉬운 식품, 음료, 약품, 의약품 등의 포장재나 단열제로 응용 가능하다. 본 연구에서는 aluminum isopropoxide를 출발물질로 하여 alumina sol을 제조한 후 실란 커플링제를 첨가하여 코팅 용액을 제조하였다. 또한, 제조된 alumina sol 용액을 이축연신 폴리프로필렌(BOPP)에 코팅하여 복합 필름을 만들고 산소 투과 특성을 측정한 결과 순수한 BOPP에 비해서 산소 투과도가 약 85% 정도 감소되는 효과를 보였다.

Sol-gel process is relatively simple, easy to use, cheap to install, and results in thin coating layers with superior physical and gas barrier properties. Films coated by the sol-gel process can be used as insulating films or packaging films for foods, chemicals, drugs, and beverages, etc. In this study, alumina sol was synthesized from aluminum isopropoxide and silane coupling agent was added to make coating solutions. In addition, biaxially oriented polypropylene (BOPP) was coated using several alumina sol solutions and their oxygen permeabilities were measured. The experimental results indicate that in the best case, the oxygen permeability of coated film was reduced by 85% compared to that of pure BOPP.
