Cellulose is a polysaccharide composed of D-glucopyranose linked by 1,4 β-glycoside bond with three hydroxyl groups. These hydroxyl groups in cellulose have an important role in the compactness of crystalline structure and in determining the physical properties of cellulose. Cellulose in nanometers size range from 10 nm to 350 nm is known as nano cellulose, which has a variety of applications due to the unique properties such as low density, biodegradable, and good mechanical properties. In the present study, we present the isolation of the nano cellulose from flaxseed hull for the first time. The isolated nano cellulose was characterized by techniques such as UV–Vis, FT-IR, BET, XRD SEM, and TEM. The nano cellulose obtained was found to be crystalline in nature with a crystallinity index of 46% and the surface area of 5 cm2/g with excellent thermal stability.

亚麻籽壳中纳米晶纤维素的分离和表征:未来的肿瘤药物递送剂

纤维素是由D-吡喃葡萄糖构成的多糖,D-吡喃葡萄糖通过1,4-β-糖苷键与三个羟基连接。纤维素中的这些羟基在晶体结构的致密性和确定纤维素的物理性质方面具有重要作用。纳米尺寸为10 nm至350 nm的纤维素被称为纳米纤维素,由于其独特的特性(例如低密度,可生物降解和良好的机械特性)而具有多种应用。在本研究中,我们首次提出了从亚麻籽壳中分离纳米纤维素的方法。分离出的纳米纤维素通过紫外-可见,FT-IR,BET,XRD SEM和TEM等技术表征。发现获得的纳米纤维素本质上是结晶的,结晶度为46%,表面积为5 cm2 / g具有出色的热稳定性。
