Electromagnetic shielding performance of CSA-PANI/PAN electrospun fiber membrane added with CB and CNT

Abstract

Electromagnetic radiation protective clothing is the main means of individual protection of electromagnetic radiation, and the ESPESF plays a key role. In this paper, 8%, 10%, and 12% pure PAN electrospinning fiber membranes were prepared, and 0.5% and 1% CSA were added to a pure PAN solution in DMF. The fibrous membrane was used to determine the most stable electrospinning process. Subsequently, 1%, 2%, 3%, 4%, and 5% carbon black (CB) was added to the 10% PAN and 1% CSA-PANI solution to prepare electrospinning. Fibrous film, and later added 0.5%, 1%, 1.5%, 2%, 2.5% of carboxy Carbon nanotube and hydroxyl Carbon nanotube in a 10% PAN and 1% CSA-PANI solution to prepare composite nanofiber membranes, Finally, the effect of the addition of various carbon materials on the electromagnetic shielding performance of electrospun fiber membranes was comparatively studied. The shielding properties of polyaniline fiber membranes added with Carbon nanotube were improved. At the same concentration, the electromagnetic shielding performance of the CNT

Controllable morphology of electrospun nanofiber membranes with tunable groove structure and the enhanced filtration performance for ultrafine particulates

“…Compared with other methods to produce nanofibers, solid, hollow, core-shell or spider reticular two-dimensional nanofiber membrane can be obtained by changing nozzle structure and controlling experimental conditions of electrospinning, and electrospinning is considered to be the most effective and general technology to produce nanofibers with controllable size, morphology and functional components [14][15][16]. These advantages make electrospinning nanofibers play a huge role in biomedical and tissue engineering materials [17,18], filtration and adsorption [19], catalysis [20], energy storage [21], electromagnetic shielding [22], sound-absorbing materials [23], oil-water separation [24], and other fields [25][26][27].…”
