microfibrilbased
Microfibril-based refers to materials and structures in which microfibrils serve as the principal building blocks. Microfibrils are slender fibrils with diameters ranging from tens of nanometers to a few micrometers and lengths that can stretch over several micrometers, yielding high aspect ratios. They occur naturally in many biological systems, notably cellulose microfibrils in plant cell walls and collagen or chitin microfibrils in connective tissues, and they can also be produced synthetically via mechanical and chemical processing to form nanofibrils.
Common microfibril types include cellulose microfibrils and proteinaceous microfibrils. As networks or lattices, they provide a
Fabrication and assembly typically involve mechanical fibrillation, enzymatic pretreatment, or selective chemical processing to release microfibrils
Key properties of microfibril-based materials include high stiffness-to-weight ratios, high surface area, tunable porosity, and pronounced
Applications span packaging and coatings, biocomposites, tissue engineering scaffolds, wound dressings, and sensing platforms. Ongoing research
