摘要

以稻草秸秆为原料

经粉碎后进行全植物秸秆的乙酰化改性

再用此乙酰化稻草同

-己内酯(

-PCL)。研究了反应时间、反应温度、及单体用量对接枝率(G%)的影响。在反应温度140℃

反应时间10h

-CL对乙酰化稻草的质量比2:1时获得的接枝率最大为39%。产物的结构和性能通过红外光谱、核磁共振、扫描电镜、X-射线衍射和热分析仪表征

结果表明乙酰化稻草秸秆已成功接枝上聚己内酯(PCL)链段

Abstract

Acetylated straw-graft-poly (

-Caprolactone) copolymer (ACSW-g-PCL) is synthesized with the grafting copolymerization of acetylated straw (ACSW) and

-Caprolactone

in which the acetylated straw is synthesized with the acylation of the ground rice straw powder. The influences of time

temperature and amount of

-Caprolactone on the grafting percentage (G%) are studied. The maximum grafting percentage (39%) was obtained at thereaction temperature 140℃

reaction time 10h and the weight ratio of caprolactone to acetylated straw 2:1. Thecomposition and structure of ACSW-

-PCL were analyzed by various methods including FTIR spectroscopy

H NMR

SEM analysis

XRD and thermal performance testing. The results show that the PCL has been grafted onto the ACSW

and the DSC proved that the thermo stability and thermoplastic property of ACSW-

-PCL are much better than that of the original straw.
