中文摘要：

双光子聚合（TPP）激光直写技术因具有超高的空间分辨率和真三维微纳制造能力，在三维微纳功能器件制造领域有着巨大的发展前景。本文介绍了碳纳米管（CNTs）复合材料分散性、定向排布和组装方面的研究进展，并详细介绍了利用TPP激光直写技术，实现多壁碳纳米管（MWNTs）在三维空间的定向排布和分子组装。通过加入硫醇（thiol）分子，提升了MWNTs聚合物复合材料的碳纳米管分散品质和掺杂浓度，增强了碳纳米管复合材料在电学、光学、机械方面的性能，并成功实现了三维碳纳米管功能器件的制造。研究表明通过将TPP激光直写技术与热退火工艺相结合，可以实现对碳纳米管簇的排列方向和位置的精确控制。

英文摘要：

The research status of dispersion, alignment and assembly of carbon nanotubes （CNTs）/polymer composite material is reviewed. In addition, the assembly and alignment in the arbitrary 3D space of multbwall CNTs （MWNTs） are realized via the laser direct writing technique based on two-photon polymerization （TPP）. The addition of thiol molecules makes the dispersion and doping concentration of CNTs in MWCNTs/polymer composites improved, and the optical and mechanical performances enhanced, and the fabrication of 3D CNTs functional devices realized. The research results indicate that, under the combination of TPP laser direct writing technique and thermal annealing process, the precise control of the orientation and placement of CNTs clusters can be achieved.
