Abstract
고분자-점토 나노복합체는 소량의 점토를 사용하여 큰 기계적 물성향상을 나타내 많은 관심을 끌고 있는 분야이다. 층상 구조를 갖고 있는 점토를 고분자 matrix에 분산하는 과정으로 요약할 수 있는 고분자-점토 나노복합체 제조는 친수성 점토 표면을 조절하는 기술, 점토의 물리적 성질을 이용하는 무기재료에 관한 지식, 고분자 합성, 고분자 유변학, 고분자 용액 거동, 기계적 물성이 복합적으로 작용하는 계이다. 이러한 복잡성을 설명하기 위해, 이 총설에서 점토 종류와 그 특성을 설명하였다. 또한 점토 특성과 고분자-점토 나노복합체 제조 방법의 연관성에 대해 설명하고, 제조된 복합체의 구조 분석과 방법에 대해 설명하였다. 그리고 복합체의 특징적인 물성을 분류한 후 그 물성과 복합체의 구조를 연관하여 살펴보았다. 마지막으로 최근의 연구 경향과 향후 연구 경향을 제시하였다.
Polymer-clay nanocomposites, a novel organic-inorganic hybrid, attract much attention from both scientific fields and engineering fields due to their balanced improvements in mechanical properties as well as diffusion behaviors, including flame-retarding and barrier properties, with small amounts of clay. Preparation of polymer-clay nanocomposites, summarized as a process for uniform dispersion of hydrophilic layered clays in hydrophobic polymer matrixes, includes several technologies and scientific phenomena, such as surface-modifications of clay layers, physical properties of clays in liquids and dried states, polymer synthesis, polymer rheology, behaviors of polymer solutions/or monomers in the confined geometry, mechanical properties of polymers and clays. To comprehend complicated physical/chemical phenomena involved in the fabrication of nanocomposites, we reviewed physical properties of clays, structures of clays in nanocomposites, characterization of nanocomposites, the relation between morphology and physical property of nanocomposites, surveyed recent research trends, and then suggested a few strategies or methods for fabrication of nanocomposites reflecting future research directions.
