Due to the low separation efficiency and poor stability, traditional polymer filtration membranes are prone be polluted difficult reuse in harsh environments. Herein, we reported a nanofibrous membrane with honeycomb–like pore structure, which was prepared by electrospinning electrospraying. During electrospraying process, addition of polydimethylsiloxane fumed SiO2 formed pores electrostatic r...

Constructing biomimetic structure and incorporating bioactive molecules is an effective strategy to achieve a more favorable cell response. To explore the effect of electrospinning (ES) nanofibrous architecture and collagen I (COL I)-incorporated modification on tuning osteoblast response, a resorbable membrane composed of poly(lactic-co-glycolic acid)/poly(caprolactone) (PLGA/PCL; 7:3 w/w) was...

aligned and random nanocomposite nanofibrous scaffolds were electrospun from polycaprolactone (pcl), poly (vinyl alcohol) (pva) and hydroxyapatite nanoparticles (nha). the morphology and mechanical characteristics of the nanofibers were evaluated using scanning electron microscopy and tensile testing, respectively. scanning electron microscopy revealed fibers with an average diameter of 123 ± 3...

In the present work, thermoplastic elastomeric nanofibers made up of a homogenous blend nitrile butadiene rubber (NBR) and Ppolycaprolactone (CL), with 80% wt rubbery component, are used to modify carbon fiber reinforced polymer (CFRP) laminate aim improving its delamination damping behavior at same time. Since nanofibrous membrane is not chemically cross-linked, fibrous morphology lost during ...

In this study, randomly oriented hydroxyethyl cellulose/polyvinyl alcohol (HEC/PVA) nanofibers were fabricated by electrospinning. The blend solutions of HEC/PVA with different weight ratio of HEC to PVA were prepared using water as solvent to fabricate nanofibers. These nanofibrous scaffolds were coated with bone-like apatite by immersing into 10x simulated body fluid (SBF) for different time ...

Tissue engineering techniques using a combination of polymeric scaffolds and cells represent a promising approach for nerve regeneration. We fabricated electrospun scaffolds by blending of Poly (3-hydroxybutyrate) (PHB) and Poly (3-hydroxy butyrate-co-3- hydroxyvalerate) (PHBV) in different compositions in order to investigate their potential for the regeneration of the myelinic membrane. The t...

PVA/PA6 composite nanofibers were formed by electrospinning. Cu(II)-PVA/PA6 metal chelated nanofibers, prepared by the reaction between PVA/PA6 composite nanofibers and Cu2+ solution, were used as the support for catalase immobilization. The result of the experiments showed that PVA/PA6 composite nanofibers had an excellent chelation capacity for Cu2+ ions, and the structures of nanofibers wer...

25 Electrospinning of polymer solutions or melts driven by a high26 voltage electric charge is a highly versatile technique that can be used 27 to generate continuous 1D polymeric fibers with diameters rang28 ing from several micrometers to tens of nanometers. Electrospun 29 nanofibrous materials possess a variety of interesting characteristics 30 such as small dimension, large specific surface...

among the synthetic polymers, poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (phbv) microbial polyester is one of the biocompatible and biodegradable copolymers in the nanomedicine scope. phbv has key points and suitable properties to support cellular adhesion, proliferation and differentiation of nanofibers. nanofibers are noticeably employed in order to enhance the performance of biomaterials,...
