| 摘要:纳米微晶纤维素(Nanocrystalline Cellulose, NCC)是一种纤维素经酸水解后获得的棒状晶体,由于其原料丰富、可再生、生物兼容性好以及机械性能优良等特点,已成为纳米材料研究领域的热点。本文为探索其进一步改性应用,重点分析了NCC表面存在的基团种类,对其化学改性方法进行了概括,并对其进一步发展应用进行了展望。 |
| Abstract:Rod-like nanocrystalline cellulose (NCC) can be prepared by acid hydrolysis of native cellulose with sulfuric acid. Because of its advantages of abundance of raw materials， renewable， biocompatible and excellent mechanical properties， it has recently received a great deal of attention in the field of nanotechnology. This paper provided an overview of recent study of functional groups on the surface of NCC， and the modification of NCC. Finally， the development of NCC in the future was prospected． |
