Abstract
Disclosed herein are nanofibrillar materials and aerogel-like materials comprised of nanofibrils, and methods for making such materials.
Claims12
A nanofibrillar material, comprising:
- nanofibrils formed from an amphiphilic polypeptide, wherein the nanofibrils have an average diameter between about 2 nm and about 40 nm and form a network of interconnected pores,
- wherein a majority of the interconnected pores are nano-sized pores that range in diameter between about 2 nm and about 100 nm, and wherein at least 50% of the nano-sized pores are in the mesoporous range in diameter between 2 nm and 50 nm;
- and
- wherein the nanofibrillar material is characterized by a porosity of at least about 80%, a bulk density that is less than about 75 kg/m3, and
- a compressive modulus between that is between about 50 kPa and about 300 kPa.
