Background:

Hydrophobic fruit skins protect against dehydration and environmental stress.
Hydrophobic encapsulation preserves hydrogel functionality but faces interfacial instability challenges.

Purpose of the Study:

To develop a robust hydrogel encapsulation strategy that stabilizes the hydrophobic shell-hydrogel interface.

Main Methods:

Utilized a liquid marble concept for encapsulation.
Formed interfacial bridges with hydrophobic particles to create a nonpolar liquid layer on the hydrogel.
Deposited a secondary hydrophobic particle layer to yield a multi-layered marble (MLM) structure.

Main Results:

Achieved stable encapsulation of various hydrogels and liquids.
Demonstrated versatility in accommodating diverse structural configurations.
Successfully maintained hydrogel performance and functionality post-encapsulation.

Conclusions:

MLM-encapsulation provides a universal and robust solution for interfacial instability in hydrogel systems.
This approach enhances the long-term stability and functionality of encapsulated hydrogels.
The strategy is adaptable for a wide range of hydrogel applications.
