Core–shell nanostructures are powerful platforms for the development of novel nanoscale drug delivery systems with sustained release profiles. Coaxial electrospinning is facile and convenient creating medicated core–shell elaborate designs which sustained-release behaviors molecules can be intentionally adjusted. With resveratrol (RES) as a model poorly water-soluble cellulose acetate (CA) PVP polymeric carriers, brand-new electrospun nanostructure was fabricated in this study. The guest RES host CA were designed to have reverse gradient distribution within nanostructures. Scanning electron microscope transmission evaluations verified that these nanofibers had linear morphologies, without beads or spindles, an obvious double-chamber structure. X-ray diffraction patterns Fourier transform infrared spectroscopic results indicated involved components highly compatible presented amorphous molecular state. In vitro dissolution tests new structures able prevent initial burst release, extend continuous-release time period, reduce negative tailing-off effect, thus ensuring better profile than traditional blended drug-loaded nanofibers. mechanism underlying influence structure RES/CA on proposed. Based proof-of-concept demonstration, series advanced functional nanomaterials similarly developed based distributions multi-chamber

Polymeric composites for manipulating the sustained release of an encapsulated active ingredient are highly sought after many practical applications; particularly, water-insoluble polymers and core–shell structures frequently explored to manipulate behaviors drug molecules over extended time period. In this study, electrospun nanostructures were utilized develop a brand-new strategy tailor spatial distributions both insoluble polymer (ethylcellulose, EC) soluble (polyvinylpyrrolidone, PVP) within nanofibers, thereby extended-release loaded ingredient, ferulic acid (FA). Scanning electron microscopy transmission assessments revealed that all prepared nanofibers had linear morphology without beads or spindles, those from coaxial processes obvious structure. X-ray diffraction attenuated total reflectance Fourier transform infrared spectroscopic tests confirmed FA fine compatibility with EC PVP, presented in amorphous state. vitro dissolution indicated radical (decreasing shell core) PVP (increasing able play their important role elaborately. On one hand, F3 advantages homogeneous composite F1 higher content solutions inhibit initial burst provide longer period release. other F2 core negative tailing-off The key element was water permeation rates, controlled by ratios polymers. new based on structure paves way developing wide variety polymeric heterogeneous realizing desired functional performances.

Ultrafast Thermal Conduction of Phase Change Fiber Enabled by Sheath Confinement‐Induced Ordered Orientation of Hydroxylated BNNs

Small, Год журнала: 2025, Номер unknown

Опубликована: Март 5, 2025

Phase change fibers (PCFs) are increasingly popular in thermal storage and release applications, such as temperature management. However, a simple but effective integration of conductive materials into PCFs to deliver ultrafast conduction remains big challenge. Herein, facile one-pot coaxial wet spinning strategy based on sheath-confinement-induced orientation arrangement hydroxylated boron nitride nanosheets (BNNs-OH) is proposed fabricate the high-performance PCFs. For core-sheath PCFs, cellulose nanofiber (CNF)-reinforced paraffin (CNF/PW) emulsions serve phase core, while dissolved well-dispersed BNNs-OH act sheath precursor. By increasing extrusion speed liquid contraction fiber gradually finalized induce alignment confinement effect. Consequently, highly oriented (f = 0.8) endow with high transition enthalpy (125.1 J g-1), excellent conductivity (10.15 W m-1K-1), rapid heat transfer rate (1.6 cm s-1); moreover, as-prepared show good tensile strength (11.21 MPa) leakage-proof (0.13%). The combined thermochromic dyes for functional fabrics or applied management phone, demonstrating dissipation.
