Abstract

In this study, cellulose microspheres from modified cotton linter (CL) and oil palm trunk fibre (OPTF) were fabricated by using simple emulsion method. The cellulose was obtained from the CL and OPTF through the alkaline pre-treatment and acid hydrolysis processes. The emulsion method was performed using polyvinyl alcohol (PVA) as an emulsifying agent. The characterization of the cellulose from CL and OPTF were analysed using Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD), and the morphological characterizations of cellulose microspheres were later observed under optical microscopy (OM) and field emission-scanning electron microscopy (FE-SEM). Based on the results, FTIR spectra displayed the lignin and hemicellulose had removed after treatments, while XRD revealed that the crystallinity index of OPTF and CL was increased after the treatments. The microspheres, formed with different ranges of size between 80 to 150 μm under OM and FESEM, showed the formation of pores on the surface of the microspheres.

以改性棉纱和油棕干纤维为原料，乳液法制备纤维素微球

以改性棉絮(CL)和油棕榈干纤维(OPTF)为原料，采用简单乳化法制备纤维素微球。通过碱前处理和酸水解得到纤维素。以聚乙烯醇(PVA)为乳化剂，进行了乳化法。利用傅里叶红外光谱(FTIR)和x射线衍射(XRD)对CL和OPTF制备的纤维素进行了表征，并在光学显微镜(OM)和场发射扫描电镜(FE-SEM)下观察了纤维素微球的形态特征。结果表明，FTIR光谱显示处理后木质素和半纤维素被去除，而XRD显示处理后OPTF和CL的结晶度指数有所提高。在OM和FESEM下形成的微球尺寸在80 ~ 150 μm之间，微球表面有孔洞形成。
