1D polymer nanomaterials have attracted significant interest in recent years because of their unique properties and promising applications in various fields. It is, however, still a challenge to fabricate polymer nanoarrays with desired sizes and controlled morphologies. Here, an unprecedented approach, the laser-assisted nanowetting (LAN) method, to selectively fabricate polymer nanoarrays is presented. Polystyrene (PS) is blended with gold nanorods (AuNRs), which are used to absorb the energy from the laser. After the blend films are brought in contact with AAO templates, the AuNRs at regions shone by the laser beams absorb the energy and heat the surrounding polymer chains, resulting in the formation of PS/AuNRs arrays in selected areas. This work paves a new research direction for developing template-based polymer nanomaterials.

激光辅助纳米润湿：使用阳极氧化铝模板选择性制造聚合物/金纳米棒阵列。

一维聚合物纳米材料近年来因其独特的性能和在各个领域的应用前景而引起了人们的极大兴趣。然而，制造具有所需尺寸和受控形态的聚合物纳米阵列仍然是一个挑战。在这里，提出了一种空前的方法，即激光辅助纳米润湿（LAN）方法，以选择性地制造聚合物纳米阵列。聚苯乙烯（PS）与金纳米棒（AuNRs）混合在一起，金纳米棒用于吸收激光的能量。使共混膜与AAO模板接触后，被激光束照射的区域的AuNRs吸收能量并加热周围的聚合物链，从而在选定区域形成PS / AuNRs阵列。这项工作为开发基于模板的聚合物纳米材料开辟了新的研究方向。
