초록
본 연구에서는 microcrystalline cellulose(MCC) 표면에 3-aminopropyltriethoxysilane(APS)를 사용하여 아미노기를 도입하는 연구를 수행하였다. 용매의 조성, APS 투입량, 팽윤시간, 반응시간 및 반응온도를 변화시켜, 각각의 반응조건이 MCC의 표면 개질 정도에 미치는 영향을 연구하였다. APS에 의한 MCC 개질 정도를 Fourier transform infrared spectroscopy(FTIR), elemental analysis(EA), X-ray photoelectron spectroscopy(XPS)와 X-ray diffraction (XRD) 분석법을 사용하여 측정하였다. APS 투입량, 팽윤시간, 반응시간과 반응온도가 증가할수록 MCC 표면에 도입되는 아미노기가 증가함을 확인하였다.
In this study, we carried out research to introduce amino groups on the microcrystalline cellulose (MCC) surface using 3-aminopropyltriethoxysilane (APS). We studied effects of solvent composition, concentration of APS, swell time, reaction time and reaction temperature on the degree of surface modification of MCC. We measured the degree of surface modification of MCC using Fourier transform infrared spectroscopy (FTIR), elemental analysis (EA), X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) techniques. It was found that the amount of surface modification by amino functional groups increased as the amount of APS, swell time, reaction time and reaction temperature were increased.
