Abstract

The cellulose microfibers (CMF) from water hyacinth (WH) fiber as a filler in sago starch (SS) biocomposites was investigated. The CMF was isolated by pulping, bleaching and acid hydrolysis methods. The addition of CMF in sago matrix was varied i.e. 0, 5, 10, 15 and 20 wt%. Biocomposites were made by using solution casting and glycerol as a plasticizer. The biocomposites were also determined by tensile test, FTIR, X-Ray, thermogravimetric, SEM, and soil burial tests. The results show that the SS15CMF sample has the highest tensile strength of 10.23 MPa than those other samples. Scanning Electron Microscope (SEM) images show that the strong interaction was formed between CMF WH and matrix. Fourier Transform Infra-red (FTIR) indicated that the functional group of biocomposites was a hydrophilic cluster. The addition of CMF WH in sago starch biocomposites lead to the moisture barrier, crystallinity, and thermal stability increased; it is due to the pure sago starch film was more rapidly degraded than its biocomposites.

摘要

水葫芦纤维的纤维素微纤维(CMF)作为填充料被应用于西米淀粉(SS)生物复合材料中。CMF 是通过制浆、漂白和酸水解方法分离得到的。CMF 在西米基质中的添加量分别为 0、5、10、15 和 20wt%。生物复合材料是通过溶液浇铸和甘油作为增塑剂制成的。还对生物复合材料进行了拉伸试验、FTIR、X 射线、热重分析、SEM 和土壤掩埋试验的测定。结果表明,SS15CMF 样品的拉伸强度最高,达到 10.23MPa,优于其他样品。扫描电子显微镜(SEM)图像显示,CMF WH 与基质之间形成了强烈的相互作用。傅里叶变换红外(FTIR)表明,生物复合材料的官能团是亲水性簇。CMF WH 在西米淀粉生物复合材料中的添加导致水分阻隔、结晶度和热稳定性增加;这是因为纯西米淀粉膜比其生物复合材料更容易降解。
