Humidity-responsive Janus polymer–inorganic films formed by evaporation-induced vertical segregation

Key Points

• To develop high-performance humidity-responsive actuators using Janus polymer–inorganic films.
• Developed Janus polymer–inorganic composite films using solution casting.
• Utilized poly((2-hydroxy-3-(methacryloyloxy)propyl)serine) and calcium phosphate oligomers.
• Created films that exhibit humidity-responsive behavior.],
• results:[
• Composite films showed rapid and reversible bending in response to humidity changes.
