In this work, Makrofol DE 1–1 films were treated with O₂ plasma for different treatment times ranging from 60 to 120 min at applied power 3.5 W and working pressure 0.4 Torr. The induced changes in Makrofol surface properties after plasma treatment were examined with Atomic Force Microscope (AFM), Scanning Electron Microscope (SEM), Photoluminescence (PL) spectroscopy, ultraviolet–visible (UV–Vis) spectroscopy techniques. The changes in the wettability property and surface free energy (SFE) of the plasma treated Makrofol polymer samples have been investigated by measuring the water and glycerol contact angles. Moreover, the induced changes in the dielectric Parameters and AC conductivity of plasma treated Makrofol samples were studied at a wide range of frequencies at room temperature. AFM analysis revealed that the average surface roughness (R_a) of Makrofol samples was increased after plasma treatment. Also SEM images clearly indicated that more enhanced surface roughness can be obtained with increasing treatment time. A noticeable increase in the intensity of PL emission spectra with increasing plasma treatment time was observed. This increase could be attributed to the increase in surface roughness and surface area of Makrofol samples after plasma treatment. The measurements of contact angle showed an enhancement in the wettability property and surface free energy of Makrofol samples after plasma treatment time. The analysis of the results of UV–Vis spectra revealed that the absorbance, Urbach energy (E_U), the refractive index (n), the extinction coefficient (k) and number of carbon per length (N) were increased while the transmission and optical energy band gap of Makrofol samples were decreased with increasing plasma treatment time. AC conductivity, dielectric constant and dielectric loss of Makrofol samples have been increased by increasing plasma treatment time.

在这项工作中，Makrofol DE 1-1 薄膜用 O ₂在 60 到 120 分钟的施加功率和 0.4 托的工作压力下，不同处理时间的等离子体。用原子力显微镜 (AFM)、扫描电子显微镜 (SEM)、光致发光 (PL) 光谱、紫外-可见 (UV-Vis) 光谱技术检查等离子体处理后 Makrofol 表面特性的诱导变化。通过测量水和甘油的接触角，研究了经等离子体处理的 Makrofol 聚合物样品的润湿性和表面自由能 (SFE) 的变化。此外，在室温下的宽频率范围内研究了等离子体处理的 Makrofol 样品的介电参数和交流电导率的诱导变化。AFM 分析表明平均表面粗糙度 (R _a) 的 Makrofol 样品在等离子体处理后增加。SEM 图像也清楚地表明，随着处理时间的增加，可以获得更高的表面粗糙度。观察到随着等离子体处理时间的增加，PL 发射光谱的强度显着增加。这种增加可能是由于等离子处理后 Makrofol 样品的表面粗糙度和表面积增加。接触角的测量表明，经过等离子处理时间后，Makrofol 样品的润湿性和表面自由能有所提高。UV-Vis 光谱结果分析表明，吸光度、Urbach 能量 (E _U)，随着等离子体处理时间的增加，折射率 (n)、消光系数 (k) 和单位长度的碳数 (N) 增加，而 Makrofol 样品的透射率和光能带隙降低。Makrofol 样品的 AC 电导率、介电常数和介电损耗随着等离子体处理时间的增加而增加。
