Abstract
The present invention provides, inter alia, compositions including at least one pliable layer comprising a plurality of silk fibroin nanofibrils, and at least one rigid layer comprising a plurality of mineral crystals, wherein each rigid layer is associated with at least one pliable layer, as well as methods for the production and use thereof.
Claims20
A filtration membrane comprising at least two filtration membrane layer structures, each of the at least two filtration membrane layer structures comprising:
- at least one pliable membrane layer comprising a plurality of silk fibroin nanofibrils;
- and
- at least one rigid membrane layer comprising a plurality of mineral crystals, wherein each rigid layer is associated with at least one pliable layer.
A method comprising
- (a) growing a plurality of mineral crystals on at least one pliable membrane layer comprising a plurality of silk fibroin nanofibrils such that the crystals form at least one rigid membrane layer associated with the at least one pliable membrane layer, thereby producing a first filtration membrane layer structure;
- (b) repeating step (a), thereby producing a second filtration membrane layer structure;
- and
- (c) forming a filtration membrane comprising the first and second filtration membrane layer structures.
