We explored surface characteristics of polycarbonate substrates which were subjected to proton and nitrogen ion beams. Curved plates designed for a plastic window of a cell phone were fabricated using injection molding, and the process was simulated numerically. Different energy densities of proton and nitrogen ion beams were applied in this study. The physical and chemical properties of the samples were evaluated using UV-Vis spectroscopy, FT-IR, differential scanning calorimetry (DSC), nanoindentation, residual stress, and electrical analyses. Results revealed that the irradiation of proton and nitrogen ion beams led to changes in the chemical structures and energy levels of the polymer molecules. Furthermore, physical properties, such as hardness, glass transition temperature, transmittance, and electrical conductivity, were remarkably varied.
我们探究了经过质子和氮离子束处理的聚碳酸酯基板的表面特性。通过注塑成型制造了用于手机塑料窗口的弯曲板，并对该过程进行了数值模拟。本研究中应用了不同能量密度的质子和氮离子束。使用紫外可见光谱、傅里叶变换红外光谱、差示扫描量热法（DSC）、纳米压痕、残余应力和电学分析对样品的物理和化学性质进行了评估。结果表明，质子和氮离子束的辐照导致聚合物分子的化学结构和能级发生变化。此外，硬度、玻璃化转变温度、透光率和电导率等物理性质也有显著变化。
