摘要

将底物浸入生物启发构建块的稀水溶液中，会在底物上沉积聚多巴胺薄膜。椭偏法测定的自聚合速度为1.6 nm/hr。为了提高反应速度，加入了强催化剂。所得速度由1.6 nm/hr提高到30 nm/hr。不同处理时间的仿生表面处理PET和ITO-PET基材用商用丙烯酸ACF与FPC组装。结果表明，即使处理时间为5 min, PET基材与FPC之间的粘附强度也从10 gf/cm以下显著提高到500 gf/cm以上，电接触电阻没有明显变化。这可能是由于电极上的仿生薄膜厚度足够低(2.5 nm)。

Bio-inspired surface treatment on touch screen panels (TSPs) for adhesion enhancement

Immersion of substrates in a dilute aqueous solution of bio-inspired building blocks resulted a deposition of polydopamine thin film on the substrate. The Self-polymerization speed measured by ellipsometry was 1.6 nm/hr. Strong catalyst was added in order to enhance the speed. The resulting speed was increased from 1.6 nm/hr to 30 nm/hr. Bio-inspired surface treated PET and ITO-PET substrates with various treatment times were assembled with FPC using commercial acrylic ACF. As a result, adhesion strength between PET substrates and FPC was enhanced dramatically from below 10 gf/cm to over 500 gf/cm even when the treatment time was 5 min. Electrical contact resistance did not show any notable changes. It was presumably due to the sufficiently low thickness (2.5 nm) of bio-inspired thin film on the electrode.
