Polycarbonate is a desirable material for many applications due to its favorable mechanical and optical properties. Here, we report a simple, safe, environmentally friendly aqueous method that uses diamines to functionalize a polycarbonate surface with amino groups. The use of water as the solvent for the functionalization ensures that solvent induced swelling does not affect the optical or mechanical properties of the polycarbonate. We characterize the efficacy of the surface amination using X-ray photo spectroscopy, Fourier transform infrared spectroscopy (FT-IR), atomic force microscopy (AFM), and contact angle measurements. Furthermore, we demonstrate the ability of this facile method to serve as a foundation upon which other functionalities may be attached, including antifouling coatings and oriented membrane proteins.
聚碳酸酯因其优良的机械和光学性能而成为许多应用的理想材料。在这里，我们报告了一种简单、安全、环保的水相方法，该方法使用二胺将氨基官能团化到聚碳酸酯表面上。使用水作为功能化的溶剂可确保溶剂诱导的溶胀不会影响聚碳酸酯的光学或机械性能。我们使用 X 射线光电子能谱、傅里叶变换红外光谱（FT-IR）、原子力显微镜（AFM）和接触角测量来表征表面氨基化的效果。此外，我们还证明了这种简单方法可以作为基础，在此基础上可以附着其他官能团，包括抗污涂层和定向膜蛋白。
