Research progress in electrospun nanofiber anti-haze screens
The research progress in the preparation methods of electrospun nanofiber anti-haze screens was reviewed in recent years.And the evaluation methods of anti-haze screens were described.Electrospun nanofiber anti-haze screens include single polymer nanofiber anti-haze screen,polymer/inorganic composite nanofiber anti-haze screen,multifunctional nanofiber anti-haze screen,etc..The electrospun nanofiber anti-haze screens have advantages such as high filtration efficiency,high reuse rate and low cost,but the filtration resistance,transparency,hydrophobicity,and other properties need to be further improved.The evalu-ation method for anti-haze screen windows should evaluate the key parameters such as filtration efficiency,transparency and hy-drophobicity.It was pointed out that the research focus of electrospun nanofiber anti-haze screen windows should be focused on the introduction of novel physical structures or chemical components on the surface of nanofibers through chemical modification technologies such as hydrothermal synthesis and chemical vapor deposition in order to significantly improve the filtration efficien-cy,hydrophobicity and air permeability and contribute functional characteristics such as UV resistance and antifungal and antivi-ral activity to nanofiber anti-haze screens.
