类玻璃碳(Glass-like Carbon，GLC)是一种非颗粒状的碳材料，其表面和断裂面具有类玻璃的外观。在本研究中，通过将热固性树脂与两种尺寸的热塑性微球混合，制备了具有大量微米级孔径的凝胶电致发光材料。对于这些凝胶载体，当它们与微球混合时，碳化产率和表观密度降低。扫描电子显微镜结果表明，与大颗粒制备的凝胶复合材料相比，掺入小颗粒的凝胶载体表面和断口具有更小的孔径。经1000℃或以上热处理的含小珠的凝胶电致发光材料的电阻与纯净的凝胶电致发光材料相比几乎没有变化。
Glass-like carbon (GLC) is an agranular carbon material with a pseudo-glass-like appearance on the surface and fractured face. In this study, GLCs with numerous micrometer-sized pores were prepared by mixing thermosetting resins with two sizes of thermoplastic microbeads. For these GLCs, the carbonization yields and apparent densities decreased when they were mixed with microbeads. SEM results suggested that the surfaces and fracture faces of GLCs mixed with small beads possess smaller pores compared to those prepared with large beads. The electrical resistances of GLCs with small beads heat-treated at 1000 ℃ or above were almost unchanged compared to those of the neat GLCs.
