초록
본 연구에서는 팽창흑연의 함량 변화를 달리하여 제조한 팽창흑연/에리스리톨 복합체의 열적거동에 관하여 고찰하였다. 팽창흑연이 도입된 팽창흑연/에리스리톨 복합체의 표면 및 구조특성은 scanning electron microscope (SEM), transmission electron microscope (TEM), 그리고 X-ray diffraction (XRD)를 이용하여 관찰하였으며, 열적특성은 differential scanning calorimetry (DSC)와 thermal conductivity (TC)를 이용하여 분석하였다. 실험 결과 팽창흑연의 함량이 증가함에 따라 팽창흑연/에리스리톨 복합체의 열전도도가 증가하였으며, 반면에 잠열은 팽창흑연의 존재 하에 약간 감소하였다. 결론적으로 팽창흑연은 상변이 물질의 높은 열 전달성능 및 열 저장능력을 향상시키는데 적합한 소재라 판단된다.
In this paper, the thermal behaviors of expanded graphite(EG)/erythritol composites with different contents of EG were studied. The surface and structure properties of the composites were determined by using scanning electron microscope (SEM), transmission electron microscope (TEM), and X-ray diffraction (XRD), respectively. The thermal properties were investigated by differential scanning calorimetry (DSC) and thermal conductivity (TC). As experimental results, the thermal conductivity of the composites increased with increasing the EG content. However, the latent heat was somewhat decreased in the presence of EG. We could concluded that EG was highly promising materials for improving the heat transfer enhancement and energy storage capacity of phase change materials (PCMs).
