AI Article Synopsis

  • Researchers have developed a magnetic fibrous membrane using a solvent-free and eco-friendly melt electrospinning method, specifically combining polycaprolactone (PCL) with iron oxide (FeO) to create the material.
  • The apparatus used for this process is lightweight (450g) and portable, making it convenient for potential medical use in therapies.
  • The resulting PCL/FeO fibers are uniform in size (4-17 μm) and have demonstrated excellent heating efficiency and thermal cycling, making them promising for applications in magnetic hyperthermia therapy.

Article Abstract

Magnetic fibrous membrane used to generate heat under the alternating magnetic field (AMF) has attracted wide attention due to their application in magnetic hyperthermia. However, there is not magnetic fibrous membrane prepared by melt electrospinning (e-spinning) which is a solvent-free, bio-friendly technology. In this work, polycaprolactone (PCL)/FeO fiber membrane was prepared by melt e-spinning and using homemade self-powered portable melt e-spinning apparatus. The hand-held melt e-spinning apparatus has a weight of about 450 g and a precise size of 24 cm in length, 6 cm in thickness and 13 cm in height, which is more portable for widely using in the medical field. The PCL/FeO composite fibers with diameters of 4-17 μm, are very uniform. In addition, the magnetic composite fiber membrane has excellent heating efficiency and thermal cycling characteristics. The results indicated that self-powered portable melt e-spinning apparatus and PCL/FeO fiber membrane may provide an attractive way for hyperthermia therapy.

In the past 30 years, researchers have worked towards reducing the size of ordinary three-dimensional (3D) materials into 1D or 2D materials in order to obtain new properties and applications of these low-dimensional systems. Among them, functional nanofibers with large surface area and high porosity have been widely studied and paid attention to. Because of the interesting properties of nanofibers, they find extensive application in filtration, wound dressings, composites, sensors, capacitors, nanogenerators, etc.

High-speed melt spinning of thermotropic liquid crystalline polymer (TLCP) resin composed of 4-hydroxybenzoic acid (HBA) and 2-hydroxy-6-napthoic acid (HNA) monomers in a molar ratio of 73/27 was conducted to investigate the characteristic structure development of the fibers under industrial spinning conditions, and the obtained as-spun TLCP fibers were analyzed in detail. The tensile strength and modulus of the fibers increased with shear rate in nozzle hole, draft in spin-line and spinning temperature and exhibited the high values of approximately 1.1 and 63 GPa, respectively, comparable to those of industrial as-spun TLCP fibers, at a shear rate of 70,000 s and a draft of 25.

Self-powered portable melt electrospinning for in situ wound dressing.

Collaborative Innovation Center for Nanomaterials & Devices, College of Physics, Qingdao University, NO. 308 Ningxia Road, Qingdao, 266071, People's Republic of China.

Background: Electrospun (e-spun) nanofibers for wound dressing have attracted wide attention due to its large specific surface area, large porosity and breathability. Compared with solution electrospinning (e-spinning), melt e-spinning is more bio-friendly without toxic solvent participation, which provides the possibility of in situ e-spinning on wounds directly. However, previously reported melt e-spinning devices were usually bulky and cumbersome due to their necessary heating unit, and different components were separated to avoid electrostatic interference.

Bubble Melt Electrospinning for Production of Polymer Microfibers.

Collaborative Innovation Center for Nanomaterials & Devices, College of Physics, Qingdao University, Qingdao 266071, China.

In this paper, we report an interesting bubble melt electrospinning (e-spinning) to produce polymer microfibers. Usually, melt e-spinning for fabricating ultrafine fibers needs "Taylor cone", which is formed on the tip of the spinneret. The spinneret is also the bottleneck for mass production in melt e-spinning.
