Abstract

These days, the quality of indoor air is a very important concept for modern people who have lived in building and is a matter of new thinking. The quality is determined by the temperature and humidity of indoor air. In addition, there is a disadvantage in that energy consumption is severe for indoor air improvement. Therefore, researches on methods to solve such problems using total heat exchange have been actively conducted. So, in this study, aminated poly(styrene-ethylene-butylene-styrene) polymers were synthesized by introducing a hydrophilic substituent, ammonium, into main chain and the properties of synthesized polymers were evaluated. The synthesis was carried out through chloromethylation and amination reactions to introduce ammonium into main chain. As a result, the water uptake and the ion exchange capacity of the synthesized polymers increased as the content of the reaction reagent solution increased. It was confirmed that the important data at the total heat exchange membrane, water vapor transmission rate also increased according to temperature, equivalent.

요즘 건물 내에서의 생활이 많아진 현대인에게 실내공기의 질은 매우 중요한 개념이고, 새롭게 생각을 해 보아야 하는 문제이다. 실내공기의 질은 실내공기의 온도, 습도 등으로 결정이 된다. 그리고 실내공기 개선을 위해서는 에너지 소비가 심하다는 단점이 있다. 그리하여, 전열교환을 이용하여 이러한 문제를 해결하려는 방법에 대한 연구가 활발히 이루어지고 있다. 따라서, 본 연구에서는 전열교환 분리막 적용을 위하여, poly(styrene-ethylene-butylene-styrene) 고분자에 친수성 치환기인 암모늄을 도입하여 아민화된 SEBS 고분자를 합성하였고, 합성고분자에 대한 특성평가를 진행하였다. 암모늄을 도입하기 위하여 클로로메틸화 반응과 아민화 반응을 통하여 합성을 진행하였다. 결과적으로 합성고분자는 반응용제의 함량이 높아질수록 함수율, 이온교환용량이 증가하였고, 전열교환 분리막에서 중요한 투습도 또한 증가함을 확인할 수 있었다.
