Copper Nanowire/Polydopamine-Modified Sodium Alginate Composite Films with Enhanced Long-Term Stability and Adhesion for Flexible Organic Light-Emitting Diodes

Yu Zhao,

Wenzhe Huang
et al.

Abstract: Copper nanowire (CuNW), with combined advantages of high conductivity and cost-effectiveness, is considered a promising material for the development of next-generation transparent conductive films (TCFs) in the field of flexible optoelectronics. However, the practical application of CuNW TCFs is hindered by some limitations, such as conductivity degradation and poor adhesion. Here, we demonstrate a stable CuNW composite film by embedding CuNWs into a polydopamine (PDA)-modified sodium alginate (NaAlg) matrix w… Show more

“…Simultaneously, when modifying a material surface to be hydrophilic, it is crucial to consider the durability of these coatings. Zhao [29] successfully developed a stable copper nanowire composite film by introducing a pDA-modified alginate matrix, resulting in an exceptionally smooth surface with remarkable interface adhesion. Various types of oxidants (e.g., CuSO 4 /H 2 O 2 [30], (NH 4 ) 2 S 2 O 8 [31], and NaIO 4 [32]) can be utilized during pDA polymerization to enhance covalent interactions and improve the stability of pDA coatings.…”

“…However, the intrinsic brittleness of ITO poses a significant limitation, as it is prone to fracturing under as little as 1% strain, thereby restricting its broader application potential . With the development of electronic devices possessing new features, especially the rapid growth of demand for flexible electronic devices such as flexible displays, flexible solar cells, flexible transistors, and flexible supercapacitors, ITO has been unable to meet the actual requirements. Therefore, researchers dedicated themselves to develop flexible conductive materials that can replace ITO, and the candidates mainly include metal nanowires, carbon nanotubes, graphene, conductive polymers, and so on.…”
