Cover: Electrospun PLLA/PEG shell/core fibers were collected and deposited in series to form ‘standing’ membranes. After washing away PEG, a highly aligned, single‐layered, hollow, fibrous PLLA membrane was obtained. High‐speed videography captured its epitaxial growth and SEM revealed hundreds of microscale hollow fibers, arranged in connected, parallel monolayers, forming an ordered, 2D microtube array (MTA). By adjusting the applied field strength and solution viscosity, an operational map was constructed and validated independently. A 5x30 cm2 MTA membrane could be prepared. These membranes are easy to manipulate into various configurations and their ability to mimic several anisotropic tissue structures make them an excellent candidate for tissue engineering scaffolds.
