摘　　要：以合成出的糠酮树脂为原料，成功地制备了聚糠酮基玻璃状炭，并对其形成过程中结构变化进行了研究。实验结果表明，合成出的聚糠酮树脂在300℃热固化时，发生芳环分子交联缩合度的增加和呋喃环断开。当试样继续热解时，碳链骨架重组为具有交联芳香环系破残留物，整个芳香环缩合反应程度进一步增加。试样进一步石墨化，其内部所形成的基本劳核排列为一紊乱的网络骨架结构；其微晶的面间距（d002）和微晶尺寸（Lc002及La002）分别为0.3604nm和1.1174nm及2.3102nm。Polyfurfuryl ketone-based glassy-like carbon was successfully prepared from furfuryl ketone resin. Fourier transform infrared spectroscopy and wide-angle X -ray diffraction analytical techniques were used to investigate the structural change of samples during different stages of processing. The experimental results show that the increasing of the cross-linking condensation degree and the scission of the furan ring occured when the synthetical polyfurfuryl ketone resin cured at 300℃. When the sample again pyrolyzed, the carbon chain skeletons of the decomposing carbon residues with the cross-linking aromatic ring were recombinated, it resulted in the increasing of the condened reaction degree of all aromatic ring further. When the sample was graphitized again. the disarrangement network ske1eton structure for the forming primitive unitary aromatic nucleus was aligned. The spacing of 1attice d002 for carbon microcrystal and the microcrystalline sise (Lc002&La002) were calculated to be 0. 3604nm and 1.1174nm & 2.3102nm respectively.
