摘要

Schematic illustration of the formation of thermally induced interfacial films from silk fibroin nanofibrils (SNF). From silk fibers to microfibril dispersions

films form under thermal evaporation

driven by the Marangoni effect and local concentration. The films exhibited a layered structure

self-supporting properties

and transparency

enabling functional coatings

including fluorescent anti-counterfeiting applications.

Abstract

Gas-liquid interfacial films have emerged as versatile materials for surface modification in biomedical applications

agriculture

and antifouling owing to their strong substrate-bonding capabilities. Silk nanofibrils (SNF)

as nanoscale b

uilding blocks of silk

exhibit exceptional mechanical stability

high crystallinity

and aqueous adaptability

making them ideal candidates for fabricating interfacial films. However

conventional fabrication methods for SNF- or protein-based interfacial films often involve complex and resource-intensive chemical processes. To overcome these challenges

this study introduces a simple and efficient strategy for preparing thermally induced SNF gas-liquid interfacial films

via

heat treatment

leveraging thermal evaporation-induced concentration to drive self-assembly. The method demonstrated broad applicability to various proteins and hydrophilic substrates

offering versatility and sustainability. Furthermore

the prepared films exhibited potential as antifouling and anti-counterfeiting functional coatings

significantly expanding the application scenarios of protein-based interfacial films.
