以铜箔为催化剂，阳极氧化铝为模板，制备了石墨二炔纳米管阵列.生长的纳米管具有光滑的表面，壁厚约为40 nm;退火后，GDNT约为15 nm。测试了石墨炔阵列的场发射性能，结果表明石墨炔阵列具有高的场发射性能。退火后的GDNs的开启电场和阈值电场分别下降到4.20和8.83 V/μm。
Graphdiyne nanotube (GDNT) arrays were prepared through an anodic aluminum oxide template catalyzed by Cu foil. The as-grown nanotubes have a smooth surface with a wall thickness of about 40 nm; after annealing, the GDNTs are about 15 nm. The morphology-dependent field emission properties of graphdiyne arrays were measured and display high performance field emission properties. The turn-on field and threshold field of GDNTs annealed decreased to 4.20 and 8.83 V/μm, respectively.
