Disclosed herein are polycationic microfibers comprising a high-aspect-ratio polymeric core, the polymeric core comprising a blend of a first core polymer and a second core polymer, and a polycationic polymer immobilized on the surface of the polymeric core. The polycationic microfibers are capable of sequestering or clearing nucleic acids, proteins, biomolecular complexes, exosomes, or microparticles from solutions and samples and may be formed into filters or integrated into filtration apparatuses. Also disclosed are methods for sequestering or clearing solutes from solutions and fluids, methods for the treatment of diseases or conditions, and methods for the prevention of diseases or conditions.

The present disclosure relates to a fiber for manufacturing a stretchable hydrophobic fiber article, the fiber including silica nanoparticles which are surface-modified such that the silica nanoparticles include a hydrocarbon chain, and a styrene-based thermoplastic elastomer, a stretchable hydrophobic fiber article manufactured therefrom, and a manufacturing method thereof. A fiber and a fiber article according to the present disclosure may have high hydrophobicity, preferably both superhydrophobicity and elasticity. Further, as the fiber and fiber article have excellent mechanical stability and chemical durability, the fiber and fiber article may stably exhibit the aforementioned high hydrophobicity and elasticity even under the harsh conditions.

Neutron radiation can be attenuated by a material comprising acrylonitrile butadiene styrene (ABS) filament infused with gadolinium, boron, gold, and/or cadmium. The metal-infused filaments are 3D-printed to form a sleeve or cover for gamma and/or alpha radiation detectors to shield, absorb and allow detection of neutrons that are converted to gamma and or alpha radiation. The materials can also allow discrimination between neutron and gamma and/or alpha radiation in a mixed radiation field. Boron-infused filaments also provide neutron shielding and can be used in the manufacture of water equivalent phantoms.

A high-stretchable high-sensitive flexible force-sensitive sensing fiber and a preparation method therefor comprising the specific preparation method is as follows: uniformly and synergistically dispersing a one-dimensional (1D) nanowire/nanotube and a two-dimensional (2D) conductive sheet layer in a thermoplastic elastomer solution; formulating a uniform dispersion solution of a certain concentration; and using a wet spinning process to prepare an elastic composite fiber with a highly oriented 1D/2D hybrid network. The above-described composite fiber is placed in a metal precursor solution to fully swell, and then placed in reductive steam for reduction, to reduce metal precursors to zero-dimensional (0D) metal nanoparticles, thereby preparing a flexible force-sensitive sensing fiber based on a 0D/1D/2D three-dimensional collaborative network.

A fiber can be made having a structure with an axial core and a coating layer. The fiber can have a polymer core and one or two layers surrounding the core. The fine fiber can be made from a polymer material and a resinous aldehyde composition such that the general structure of the fiber has a polymer core surrounded by at least a layer of the resinous aldehyde composition.
