| 针对热转变材料制备成本高昂的问题，用一种低成本的修饰-加热-再修饰的方法实现了磷铜片表面的浸润性的快速转变。用蒸馏水浸渍的方法在磷铜片表面制备了致密的Cu2O纳米棒，经十二烷基硫醇表面改性后表现出优异的超疏水性能。同时，将制备好的磷铜片在160 ℃的烘箱保存30 min，该表面浸润性可实现从超疏水到亲水的快速转变，并且转变后的表面经十二烷基硫醇重新修饰后可恢复其超疏水特性。结果表明，制备好的磷铜片在加热过程中产生了大量的RS-SR化合物，RS-SR化合物经乙醇冲洗脱离磷铜片表面导致表面碳含量降低，最终导致表面浸润性的转变。该工作提供了一种制备热浸润性快速转变材料的简单方法，在微控制和智能器件领域具有潜在应用。 |

| Abstract: |
| With a view to costly fabrication of thermal response material, a simple economical modificate-anneal-remodificate method was developed to realize fast wet transition on phosphor-copper foil surfaces. Highly dense porous Cu2O rods were deposited on commercial phosphor-copper foil by using a distilled water immersion method. After surface modification with 1-dodecanethiol, the phosphor-copper foil exhibited excellent superhydrophobicity. Interestingly, the wettability of the as-prepared surface can be adjusted from superhydrophobicity to hydrophilicity after heated at 160℃ for 30 min, and the resultant phosphor-copper foil can restore its superhydrophobic properties by re-modification with 1-dodecanethiol. The results indicate that numerous disulfide RS-SR bonds are generated on the surface during heating. After rinsing with ethanol, the disulfide RS-SR bonds can be easily removed from the surface, thereby leading to decrease of surface carbon content as well as change of the surface wettability. Hopefully, the present strategy could provide a facile method to fabricate thermal fast response material and have promising application in micro-control and intelligent device fields. |
