Abstract

Novel composite (MC/TiO₂) films consisting of titanium dioxide nanoparticles (TiO₂NPs) and organic polymer methylcellulose (MC), were synthesized for applied in photocatalysis and industrial sectors. The preparation of the nanocomposites MC/TiO₂ films were verified successfully by EDX technique, which demonstrated the uniform distribution of TiO₂ in the MC. Moreover, in frequency of 20 Hz to 5.5 MHz, the dielectric properties of MC as a function of TiO₂ concentration were determined. The conductivity improved from 5.8 × 10⁻⁸S.cm⁻¹ for MC to 3.8 × 10⁻⁶S.cm⁻¹ for the composite MC/TiO₂, and the dielectric constant

ε′

has risen from 87 for MC to 179 for the composite MC/TiO₂. In addition, the energy density increases from 3.86 × 10⁻⁴J m⁻³ for MC to 7.94 × 10⁻⁴J m⁻³ for MC/TiO₂, and the relaxation time

τr

dropped from 11.5 × 10⁻⁵ sec to 2.58 × 10⁻⁵. In summary, the data investigated that the dielectric characteristics of MC/TiO₂ were modified for usage in different applications as wastewater treatment and energy storage devices.

二氧化钛纳米粒子对提高工业应用有机聚合物材料性能活性的影响

研究人员合成了由二氧化钛纳米粒子（TiO2NPs）和有机聚合物甲基纤维素（MC）组成的新型复合膜（MC/TiO2），并将其应用于光催化和工业领域。EDX 技术成功验证了 MC/TiO2 纳米复合材料薄膜的制备，证明了 TiO2 在 MC 中的均匀分布。此外，在 20 Hz 至 5.5 MHz 频率范围内，还测定了 MC 的介电性能与 TiO2 浓度的函数关系。电导率从 MC 的 5.8 × 10-8 S.cm-1 提高到 MC/TiO2 复合材料的 3.8 × 10-6 S.cm-1 ，介电常数 ε′ 从 MC 的 87 上升到 MC/TiO2 复合材料的 179。此外，能量密度从 MC 的 3.86 × 10-4 J m-3 增加到 MC/TiO2 的 7.94 × 10-4 J m-3，弛豫时间 τr 从 11.5 × 10-5 秒下降到 2.58 × 10-5。总之，这些数据表明 MC/TiO2 的介电特性得到了改变，可用于废水处理和储能装置等不同应用领域。
