Abstract
Official abstract text for this publication.
In accordance with one embodiment, a polymer composite comprises a filler and a matrix. The filler comprises an electrospun polymer mat. The matrix comprises a polymer film. The filler is arranged to respond to stimuli by altering its mechanical properties. In one example, the mat can be electrospun from poly(vinyl alcohol), and the matrix can be formed from ethylene oxide-epichlorohydrin 1:1 copolymer. The filler can be arranged so that the tensile storage modulus of the polymer composite changes in response to the filler being exposed to a stimulus. In another example, the filler is about four percent by weight of the polymer composite.
First claim
Opening claim text (preview).
What is claimed is: 1. A polymer composite comprising: a filler comprising an electrospun polymer mat of a first material; a matrix comprising a polymer film of a second material; wherein the electrospun polymer mat is soaked in methanol and then the electrospun polymer mat is soaked in the second material to form the polymer composite; further wherein the filler is arranged to respond to a stimulus so that the mechanical properties of the polymer composite change. 2. The polymer composite of claim 1 , wherein the first material is poly(vinyl alcohol). 3. The polymer composite of claim 1 , wherein the second material is ethylene oxide-epichlorohydrin 1:1 copolymer. 4. The polymer composite of claim 1 , wherein the filler is about four percent by weight of the polymer composite. 5. The polymer composite of claim 1 , wherein the filler can be arranged so that the tensile storage modulus of the polymer composite changes in response to the filler being exposed to a stimulus. 6. The polymer composite of claim 1 , wherein the filler can be arranged so that the transparency of the polymer composite changes in response to the filler being exposed to a stimulus. 7. The polymer composite of claim 1 , wherein the filler can be arranged so that the shape memory of the polymer composite changes in response to the filler being exposed to a stimulus.
