A roll-to-roll continuous process was developed to manufacture large-scale multifunctional poly(dimethylsiloxane) (PDMS) films embedded with thickness direction ("Z" direction) aligned graphite nanoparticles by application of electric field. The kinetics particle "Z" alignment and chain formation studied tracking the real-time change optical light transmission through film direction. Benefiting from anisotropic structure chains, electrical thermal properties nanocomposites were dramatically...
Cellulose paper-based materials are highly flexible, hydrophilic, low-cost, and environmentally friendly good substrates for use as humidity sensors. Therefore, developing a sensor with facile fabrication, low cost, high sensitivity is important expanding its practical applications. Herein, we propose CI/FP self-powered based on everyday items such writing drawing carbon ink (CI), cellulose filter paper (FP), polyester conductive adhesive tape, which fabricated the help of dip-coating...
Abstract Polymer composites are ubiquitous and indispensable in numerous applications. Coupling the inclusion of reinforcing agents with methods developed to control filler distribution orientation allow for significant enhancement mechanical, thermal, electrical, barrier/transport‐related properties composites. For practical implementation, ideal approaches fabricating polymer directionally assembled fillers must consider manufacturing compatibility, scale‐up ease, aligning efficiency. In...
Roll-to-roll (R2R) processing enables the rapid fabrication of large-area sheets cooperatively assembled materials for production mesoporous materials. Evaporation induced self-assembly a nonionic surfactant (Pluronic F127) with sol–gel precursors and phenolic resin oligomers (resol) produce highly ordered mesostructures variety chemistries including silica, titania, tin oxide. The cast thick (>200 μm) film can be easily delaminated from carrier substrate (polyethylene terephthalate, PET)...
A roll to continuous processing method is developed for vertical alignment ("Z" alignment) of barium titanate (BaTiO3) nanoparticle columns in polystyrene (PS)/toluene solutions. This accomplished by applying an electric field a two-layer solution film cast on carrier: one the top sacrificial layer contacting electrode and second polymer dispersed with BaTiO3 particles. Flexible Teflon coated mesh utilized as that allows evaporation solvent through openings. The kinetics particle chain...
A combination of transparency, electrical conductivity and flexibility is desired in the emerging flexible electronics industry for current future applications.
A facile method to fabricate hierarchically structured fiber composites is described based on the electrospinning of a dope containing nickel and manganese nitrate salts, citric acid, phenolic resin, an amphiphilic block copolymer. Carbonization these mats at 800 °C generates metallic Ni-encapsulated NiO/MnOx/carbon composite fibers with average BET surface area (150 m2/g) almost 3 times higher than those reported for nonporous metal oxide nanofibers. The diameter (∼900 nm) nearly invariant...
We report the design of a series polyesters containing pendant secondary amide groups to probe cumulative effects hydrogen bonding and chain flexibility on their thermal, mechanical, rheological properties. Reported studies polymers with have usually focused effect interactions self-assembly, or self-healing properties, whereas has often been overlooked. In an effort flexibility, in this work were designed either one two amide-propyl compared control polyester ester-propyl group. The results...
A real-time spectral birefringence technique was implemented to follow the coupled relationships among birefringence, true stress, and strain behavior of natural rubber vulcanizates containing a series clay concentrations. The dynamics structural evolution also followed by off-line wide-angle X-ray diffraction characterize order orientation at different extension levels. results show that same level rubber/organomodified (NR/OC) nanocomposite with higher OC content exhibits stress...
A multi-layer solution casting method was utilized to fabricate a three-layer wound dressing film consisting of contact layer, an absorbing layer and backing layer. The whose function is absorb retain the exudate thus providing moist environment for healing, made superabsorbent particles thermoplastic polyurethane matrix. In this study, were aligned into chains axes oriented along thickness direction by external electric field. This structure could minimize lateral swelling while...

Hydrogels can encapsulate large quantities of water within a three‐dimensional crosslinked polymer network. Polyvinyl alcohol (PVA) hydrogels have been widely used in tissue engineering, wound dressing, and drug delivery. However, the inferior mechanical properties PVA limit their utility load‐bearing applications. To alleviate this deficiency, we hybrid electrospinning/solution casting continuous process to reinforce using polyurethane nanofibers. In process, nanofibers were electrospun...
