3D polymer nanofiber membrane composed of 1D individual polymer nanofibers which are quasi-aligned and cross-laminated like grid structure with functions of controlling pore distribution and size, and manufacturing method thereof1차원의 고분자 나노섬유들이 준정렬된 그리드 형상으로 직교하여 적층되어 기공 분포 및 기공 크기가 제어된 3차원 고분자 나노섬유 멤브레인 및 그 제조방법
Disclosed is a 1D nanofibers quasi-aligned, grid structure cross-laminated, and pore distribution and size controlled 3D polymer nanofiber membrane, and manufacturing method thereof. A 3D polymer nanofiber membrane controlled in pore size and porosity is formed by employing an electrospinning pattern forming apparatus that includes double insulating blocks quasi-aligns nanofibers in a specific direction by transforming an electric field and includes a current collector rotatable in 90°. Additionally, the 3D polymer nanofiber membrane may be used for air filters, separator, water filters, cell culture membranes, and so on by allowing various properties thereto through a functional surface coating.
