Abstract
Some embodiments of the invention include an article of manufacture that is self-sealing, and a method of preparing the article of manufacture. The article of manufacture includes at one or more base layers with a plurality of overlapping strands, and at least one polymer coating layer at least partially covering at least some portions of at least some strands of at least a portion of the base layer. The polymer coating layer can swell by absorbing at least one target substance. A plurality of voids is distributed between at least some of the overlapping strands, where upon swelling by a target substance, at least some of the voids reversibly reduce in size or partially close, or completely seal.
Claims20
An article of manufacture comprising:
- at least one base layer comprising a plurality of overlapping strands;
- at least one polymer coating layer at least partially covering at least some portions of at least some strands of at least a portion of the at least one base layer, the at least one polymer coating layer configured and arranged to swell by at least partially absorbing at least one target substance;
- and
- a plurality of voids distributed between at least some of the overlapping strands, wherein upon swelling by the at least one target substance, at least some of the voids reversibly reduce in size, partially close, or completely seal.
A method of preparing a self-sealing material or surface comprising:
- providing at least one base layer comprising a plurality of overlapping strands and a plurality of voids distributed between at least some of the overlapping strands;
- applying at least one polymer coating layer to the at least one base layer so that at least some of the at least one polymer coating layer at least partially covers at least some portions of at least some strands of at least a portion of the at least one base layer,
- the at least one polymer coating layer swellable by at least partially absorbing at least one target substance;
- and
- wherein upon swelling by the at least one target substance, at least some of the voids reduce in size or partially close, or completely seal.
