Novel transparent nano-pattern window screen for effective air filtration by electrospinning

In this paper, novel transparent nano-pattern window screen was successfully prepared by electrospinning. SEM, VHX 3D digital microscope and tensile tester were employed to characterize the morphology and the mechanical properties, which indicated that the nanofibers in the PA66 nano-patterned membranes are uniform and the diameter of about 200 nm, and there is no adhesion between nanofibers. In addition, we could find that the surface of the PA66 transparent nano-patterned membrane was more flat. Simultaneously, Mechanical properties of the PA66 nano-pattern membrane are better than those of the PA66 random orientation membrane. Moreover, applications of the PA66 transparent nano-pattern window screen as a filter for air filtration, we could find that the window screen showed excellent filtration efficiency for the PM0.3-5.

本文通过静电纺丝成功制备了新型的透明纳米图案窗口屏幕。 用SEM，VHX 3D数字显微镜和拉伸试验机表征了形貌和力学性能，表明PA66纳米图案膜中的纳米纤维是均匀的，直径约200nm，纳米纤维之间没有粘附。 此外，我们可以发现PA66透明纳米图案膜的表面更平坦。 同时，PA66纳米图案膜的机械性能优于PA66随机取向膜的机械性能。 此外，将PA66透明纳米图案窗口滤网用作空气过滤器时，我们发现该窗口滤网对PM0.3-5表现出优异的过滤效率。
