Superhydrophobic and oleophobic fibers by coaxial electrospinning.
Control of surface wetting properties to produce strongly hydrophobic or hydrophilic effects is at the heart of many macro- and microfluidic applications. In this work, we have investigated coaxial electrospinning to produce core-sheath-structured nano/microfibers that combine different properties from individual core and sheath materials. Teflon AF is an amorphous fluoropolymer that is widely ...
متن کاملSuperhydrophobic surfaces by electrospinning of polymer mixtures
Hydrophobic surfaces have found great interest in environment resist coating, antifouling marine structures and low friction devices whereas superhydrophobic materials, with contact angle higher than 150° [1], are of special interest in self-cleaning surfaces and stain resistant textiles. (Super)hydrophobicity is a key property that depends on both the surface chemistry and surface roughness. N...
متن کاملElectrospinning: A whipping fluid jet generates submicron polymer fibers
Polymeric fibers with diameters in the range from 50 nm to 5 mm are produced by accelerating a fluid jet in an electric field, in a process known as ‘‘electrospinning.’’ Here we show that an essential element of the process is a fluid instability, the rapidly whipping jet. The phenomena responsible for the onset of whipping are revealed by a linear instability analysis that describes the jet be...
متن کاملFeedback System Control Optimized Electrospinning for Fabrication of an Excellent Superhydrophobic Surface
Superhydrophobic surface, as a promising micro/nano material, has tremendous applications in biological and artificial investigations. The electrohydrodynamics (EHD) technique is a versatile and effective method for fabricating micro- to nanoscale fibers and particles from a variety of materials. A combination of critical parameters, such as mass fraction, ratio of N, N-Dimethylformamide (DMF) ...
متن کاملFabrication of a superhydrophobic surface from porous polymer using phase separation
The present work reports a simple method to fabricate superhydrophobic porous polymeric surfaces by a phase separation process. The method involves the in situ polymerization of butyl methacrylate (BMA) and ethylene dimethacrylate (EDMA) in the presence of co-porogens of 1,4-butanediol (BDO) and N-methyl-2-pyrrolidone (NMP) to afford superhydrophobic surfaces with the micro/nano roughness struc...
