Abstract
To improve Na+-saponite(SPT) film flexibility, we prepared SPT hybrid clay films with various poly(vinyl alcohol) (PVA) concentrations(0~10 wt%) using the solution intercalation method. In this study, we investigated the thermo-optical properties, morphology, and gas permeability of the SPT hybrid films. We also examined the relationship between the film properties and PVA content using wide angle X-ray diffraction measurements(XRD), field emission scanning electron microscopy(FESEM), differential scanning calorimetry(DSC), thermogravimetric analysis(TGA), thermomechanical analysis(TMA), ultraviolet.visible(UV-vis) spectroscopy, and oxygen transmission rate(O2TR) testing. The properties of the clay hybrid films were strongly affected by PVA filler content. The presence of a small amount of PVA was sufficient to improve the flexibility of SPT hybrid films.

Na+-사포나이트(saponite, SPT) 필름의 유연성을 향상시키기 위해 수용성 고분자인 폴리(비닐 알코올)(poly(vinyl alcohol); PVA)을 다양한 함량(0∼10 wt%)으로 사용하여 용액 삽입방법을 통해 SPT 하이브리드 필름을 제조하였다. 본 논문에서는 SPT 하이브리드 필름의 열적·광학적 성질, 모폴로지, 및 가스 투과성 등을 조사하였다. PVA 농도에 따른 SPT 하이브리드 필름의 성질들은 X-선 회절도(XRD), 전계방사형 주사전자현미경(FE-SEM), 시차주사 열량계(DSC), 열중량 분석기(TGA), 열기계 분석기 (TMA), 자외선-가시광선(UV-vis.) 흡광도기, 및 산소투과(O2TR) 측정기 등을 통해 조사하였다. SPT 하이브리드 필름의 성질들은 PVA의 무게% 농도에 따라 많은 영향을 받았으며, 적은 양의 PVA도 SPT 하이브리드 필름의 유연성을 증가시키기에 충분하였다.
