摘要

包合复合物(ICs)是超分子化学的重要组成部分。以尿素作为主体分子

PEO作为客体分子

通过共沉淀法制备了不同PEO与Urea比例的PEOUIC

而后分别利用DSC、XRD、SEM、POM分析了PEOUIC晶体的形貌与结构。结果表明:利用共沉淀法可制备六方以及四方晶系的PEOUIC晶体;当PEO与Urea质量比小于为1时

形成四方晶系PEOUIC晶体;而当质量比大于1时

形成六方晶系PEOUIC晶体;随着Urea含量的增大

PEOUIC的T

先增大在趋于稳定不变;四方晶系PEOUIC晶体呈现球晶形貌

六方晶系呈现中心突起的六边形柱状体形貌。

Abstract

The inclusion comlexes (ICs) is a topic of current interest in supermolecular chemistry. In this paper

urea was taken as host and Polyoxyethylene (PEO) as guest

and the PEO-Urea-ICs (PEOUICs) with different ratio of PEO to Urea were prepared by using co-precipitation method. And then the morphology and structure of PEOUIC were systematically analyzed by utilizing DSC

XRD

SEM and POM. The results show that: firstly

hexagonal and tetragonal PEOUIC can be obtained by co-precipitation method. Secondly

tetragonal PEOUIC is formed when the mass ratio of PEO to Urea is lower than 1

while hexagonal PEOUIC is formed when the mass ratio of PEO to Urea is higher than 1. Thirdly

with increasing of Urea

the melting point of hexagonal PEOUIC increases firstly and then tends to be stable. Fourthly

tetragonal PEOUIC with huge spherulitic morphology can be observed

and hexagonal PEOUIC possesses hexagonal column morphology with protuberant centre.
