Abstract
The effect of microwave expansion on the surface functional groups of tobacco stem by conventional stem cutting method was studied.The stem was characterized by X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FT-IR).The FT-IR result showed that:after microwave treatment,the percentage of surface hydroxyl,carboxyl and -CN increased significantly.There was no significantly different between traditional cut stem and novel cut stem during FT-IR tests.The XPS result showed that phenolic hydroxyl,ether,carboxy were three forms of carbon in microwave expansion stem.The forms of oxygen in all samples were similar,and expanded stem had higher content of hydroxyl than original stem.In addition,there were many nitrogen groups in the surface of the expanded stem molecule.
