“…Recently, several methods have been reported to achieve strong adhesive force between copper film and polyimide with micrometer line and scale without creating micrometer-scale surface roughness. For example, Neoh et al [8][9][10][11][12][13][14] and Inagaki et al [15][16][17][18][19] modified polyimide by graft polymerization of vinylimidazole or vinylpyridine. The plated copper layer interacts with the nitrogen group of the graft polymer, which creates a strong adhesive force between the PI and the copper layer.…”

ABSTRACT:In this paper, we describe a technique to prepare a copper layer on polyimide film using a polymer nanosheet as a nano-adhesion. We employ two kinds of functional polymer nanosheets: one works as an adhesion layer and the other works as a template layer to adsorb gold nanoparticles, which works as a catalyst for the electroless plating. The photoreactive polymer nanosheet was used to increase the adhesion force between the copper layer and polyimide. Furthermore, the cationic polymer nanosheets were used to adsorb a gold catalyst for electroless copper plating. Applying the technique, electroless plated copper was attached strongly onto polyimide film. Micrometer copper lines were fabricated by photopatterning the polymer nanosheets. The process using polymer nanosheets as an adhesive required no surface modification of polyimide substrate and enabled microscale copper line fabrication without discharging harmful waste. Consequently, the technique is useful for next-generation flexible printed board fabrication.

“…The vinylpyridine monomer has been identified as an adhesion promoting agent for metal-polymer interfaces due to the strong interaction of the pyridine functional group [21,22]. In the work carried out by Huang et al [8], mentioned above, it is also found that the addition of polystyrene to the blend of PCBM and the low molecular weight donor improves the adhesion.…”

Improving the Efficiency of Organic Solar Cells upon Addition of Polyvinylpyridine

We report on the efficiency improvement of organic solar cells (OPVs) based on the low energy gap polyfluorene derivative, APFO-3, and the soluble C60 fullerene PCBM, upon addition of a residual amount of poly (4-vinylpyridine) (PVP). We find that the addition of 1% by weight of PVP with respect to the APFO-3 content leads to an increase of efficiency from 2.4% to 2.9%. Modifications in the phase separation details of the active layer were investigated as a possible origin of the efficiency increase. At high concentrations of PVP, the blend morphology is radically altered as observed by Atomic Force Microscopy. Although the use of low molecular weight additives is a routine method to improve OPVs efficiency, this report shows that inert polymers, in terms of optical and charge transport properties, may also improve the performance of polymer-based solar cells.
