Direct electrospinning

The preparation of rrltrafine antimicrobial cellnlose acetate (CA) fibres with silver nanoparticles by direct electrospinning of a CA solution containing low levels of silver nitrate and characterised by viscosity, strrface tension and conductivity, followed by photoreduction using UV irradiation, is described. The fibres were characterised by SEM, TEM, XPS arrd artfirrticrobial activity and the resrrlts are discussed. 24 refs. [Pg.37]

Kang et al. first used direct electrospinning of PU onto the substrate fabrics (polyester/nylon blended fabric, which contained stainless steel yarn in weft) to prepare the waterproof-breathable fabric. PU was solvent electrospun onto the substrate fabric to develop the waterproof-breathable fabric with lightweight and thermal insulation [22], The reported air permeability and WVT rate were 0.5 cm /cm /sec and 375.80 g/h/m, respectively, for electrospun PU coated fabric, which were far better than the PU coated fabrics. Lee et al. developed electrospun PU layered fabric systems in which nanofibrous web was layered on spunbonded nonwoven to check the possibility of developing protective clothing materials as barriers to liquid diffusion (Fig. 14.2a-c). Layered clothing systems with electrospun... [Pg.358]

Electrospinning is a method allowing creation of polymer fibers with diameters in the range between a few tens of nanometers to a few micrometers, starting from a solution of preformed polymer. MIP nanoparticles have been included into nanofibers by electrospinning [126, 127], In another case, the nanofibers were directly produced by electrospinning and polymerizing an MIP-precursor solution [128]. Such MIP fibers can then be used, for example, for the preparation of affinity separation materials [129] or as affinity layers in biosensors [127, 130]. [Pg.103]
