Laser nanostructuring of thin films of PEDOT:PSS on ITO: Morphology, molecular structure and electrical properties

Fabrication and Nanoscale Properties of PEDOT:PSS Conducting Polymer Nanospheres

“…The increasing interest in finding reproducible and economic ways to tailor PEDOT:PSS nanostructures, has found recent interest in the scientific community, looking towards the use of advanced techniques and methodologies. In this context, Gutiérrez-Fernández et al recently reported the nanopatterning of PEDOT:PSS thin films by laser induced periodic surface structures (LIPSS) [18]. The resulting nanograting consisted of electrically conducting ripples, opening a path to new possible applications of this material.…”

Fabrication of large‐area linear and nonlinear surface ripple structures on polystyrene films

“…5 Currently, the following thermoplastic polymer films can be made into microscale or nanoscale ripple structures: polystyrene (PS), [6][7][8] poly (methyl methacrylate) (PMMA), 9 polyethylene terephthalate (PET), 10 polyvinyl acetate, 11 and poly (ε-caprolactone) (PCL). 8 These thermoplastic films can be made into microscale or nanoscale ripple structures by the following methods: laser-induced periodic surface structuring, 5,[12][13][14][15][16][17] ion beam milling, 18 stick-slip friction, 19 mechanical buckling, [20][21] and fractureinduced structuring (FIS). 22 Among these methods, FIS has the greatest potential to generate large-area ripple structures.…”

“…A critical conclusion is that the period of the ripple structure is always four-times greater that the thickness of the polymeric film, regardless of its average molecular weight and chemical composition. 16 Some studies 23,24 used FIS to manufacture micro-ripple or nano-ripple structures of PMMA photoresists. The ripple structure is produced by surface residual stress, and a relationship between the surface residual stress and the spatial frequency and film thickness has been established.…”

“…Application of the FIS method to manufacture ripple structures must satisfy the following conditions: (a) the operating temperature should be lower than the glass transition temperature of the polymer film; (b) the polymeric film must be a brittle amorphous material; (c) the polymeric film must have excellent adhesion to the rigid substrate. A critical conclusion is that the period of the ripple structure is always four‐times greater that the thickness of the polymeric film, regardless of its average molecular weight and chemical composition 16 . Some studies 23,24 used FIS to manufacture micro‐ripple or nano‐ripple structures of PMMA photoresists.…”
