Transparent Nanocomposites with Ultrathin, Electrospun Nylon-4,6 Fiber Reinforcement
Transparent sheets of epoxy resin reinforced with nylon-4,6 nanofibers are described. The 30-200 nm diameter fibers, obtained by electrospinning from formic acid solutions, are reported to provideExpand
Fabrication of nanostructures with long-range order using block copolymer lithography
Block copolymer lithography makes use of the self-assembling properties of block copolymers to pattern nanoscale features over large areas. Although the resulting patterns have good short-rangeExpand
Single molecule lifetime fluctuations reveal segmental dynamics in polymers.
We present a single molecule fluorescence study that allows one to probe the nanoscale segmental dynamics in amorphous polymer matrices. By recording single molecular lifetime trajectories ofExpand
Mechanical Properties of a Single Electrospun Fiber and its Structures
A method to measure the Young's modulus of a single electrospun polyacrylonitrile (PAN) fiber is reported. The Young's modulus can be calculated from the force-displacement curves obtained by theExpand
Formation of a Cobalt Magnetic Dot Array via Block Copolymer Lithography
Single-domain cobalt dot arrayswith high magnetic particle density, patterned over large areas (e.g., 10 cm diameter wafers) are fabricated by self-assembled block copolymer lithography, using aExpand
Hydrophobic recovery of UV/ozone treated poly(dimethylsiloxane): adhesion studies by contact mechanics and mechanism of surface modification
Silicone elastomers (Sylgard 184 and 170), based on poly(dimethylsiloxane) (PDMS), were surface treated by a combined exposure to UV and ozone. The effects of the treatments were analyzed as aExpand
Stable and transparent superhydrophobic nanoparticle films.
TLDR
The dip-coating method can be applied to glass substrates to prepare surfaces that are superhydrophobic and transparent and enhanced by sintering of the nanoparticles in an O2 environment at high temperature (1100 degress C). Expand
Quantitative mapping of elastic moduli at the nanoscale in phase separated polyurethanes by AFM
Abstract The micro phase separated nanoscale morphology of phase separated polyurethanes (PUs) was visualized by atomic force microscopy (AFM) height and phase imaging of smooth surfaces obtained byExpand
Electrospinning of ultra-thin polymer fibers
The electrospinning technique was used to spin ultra-thin fibers from several polymer/solvent systems. The diameter of the electrospun fibers ranged from 16 nm to 2 μm. The morphology of these fibersExpand
Templated Self-Assembly of Block Copolymers: Effect of Substrate Topography†
Topographical confinement is used to template the formation of nanoscale domains in a self-assembled block copolymer film. The topographical template controls the row spacings and feature dimensionsExpand
