Drawing Suspended Polymer Micro/Nanofibers Using Glass Micropipettes
This paper proposes a method for fabricating suspended micro/nanoscale polymer fibers continuously, in which polymeric micro/nanofibers are formed by drawing and solidification of a viscous liquid polymer solution which is pumped through a glass micropipette. By controlling the drawing parameters, this method is demonstrated to form networks of suspended fibers having amorphous internal structu...
متن کاملGlass transitions of freely suspended polymer films
We present a modified version of our " sliding model " , where chain arcs, between two contacts at the surface, may move if all the barriers along the arc are weaker than a certain threshold. An important advance of the revised model is that the high limiting chain lengths N * observed in the experiments (N * ∼ 10 4) are naturally accounted for. In this model, a film of thickness h < 2R 0 (wher...
متن کاملOriented nanomaterial air bridges formed from suspended polymer-composite nanofibers.
In a two-step method, carbon nanotubes, inorganic nanowires, or graphene sheets are connected between two anchor points to form nanomaterial air bridges. First, a recently developed method of forming directionally oriented polymer nanofibers by hand-application is used to form suspended composite polymer-nanomaterial fibers. Then, the polymer is sacrificed by thermally induced depolymerization ...
متن کاملPolymer Composite with Carbon Nanofibers Aligned during Thermal Drawing as a Microelectrode for Chronic Neural Interfaces.
Microelectrodes provide a direct pathway to investigate brain activities electrically from the external world, which has advanced our fundamental understanding of brain functions and has been utilized for rehabilitative applications as brain-machine interfaces. However, minimizing the tissue response and prolonging the functional durations of these devices remain challenging. Therefore, the dev...
متن کاملRippling of polymer nanofibers.
This paper studies the evolution mechanism of surface rippling in polymer nanofibers under axial stretching. This rippling phenomenon has been detected in as-electrospun polyacrylonitrile in recent single-fiber tension tests, and in electrospun polyimide nanofibers after imidization. We herein propose a one-dimensional nonlinear elastic model that takes into account the combined effect of surfa...
