大尺寸(厘米长)的双壁碳纳米管(DWNT)束在其重叠的末端与DWNT薄膜包扎后，通过电流辅助激光照射进行连接。在激光加工过程中，在连接处发生了DWNT束的结构转变，提供了链之间的分子键。拉伸试验表明，该方法制备的接头具有较高的抗拉强度，最大值为335.6 Mpa，相当于原始钢绞线的抗拉强度。在研究其电阻率随温度变化的过程中，连接链的电学性质并没有受到太大的削弱。这项工作可能为未来大尺寸碳纳米管结构在许多领域的广泛应用提供潜在的前景。
Macro-sized (centimeters long) double-walled carbon nanotube (DWNT) strands were connected by current-assisted laser irradiation after bandaging their overlapped ends with DWNT films. During the laser processing, structural transformation of DWNT bundles happened at the joints, which provided molecular bonding between the strands. Tensile tests indicate that the joints made in this way have relatively high tensile strength with a maximum value of 335.6 MPa corresponding to that of the original strands. And the electronic properties of the connected strands were not greatly weakened in our investigation on their temperature dependence of resistivity. This work may offer a promising potential for future extensive use of macro-sized carbon nanotube structures in many fields.
