## Description

- description: Droplet coalescence is ubiquitous in nature, and its regulation is
    significant in industrial processes and biomedical applications. While bare droplets
    suddenly coalesce in contact, the droplets covered with liquid-repellent particles
    to form “liquid marbles (LMs)” are not. Previously, the external stimuli-responsive
    breakage of the particle layer enabled the regulation of the coalescence timing.
    However, preprogramming the coalescence timing of droplets without stimuli is
    challenging. In this work, we report LMs that break the particle layer in preprogrammed
    time. The particles have a core wettable site and are tethered with a low-wettability
    flexible molecular chain, which gradually increases wettability with time. The
    time-dependent wettability variation is owing to the adaptation of the molecular
    chain; thus, it is repeatedly available, and its speed is controllable by chain
    length. The formed LMs expose bare droplet surfaces in preprogrammed timing, which
    enables the modulation of coalescence timing from 2 to 40 minutes without relying
    on external stimuli. Moreover, the additivity of the particles enabled the fine-tuning
    of the coalescence time with 1-minute resolutions. Further, the contact of several
    LMs with different adaptation times enabled cascade droplet coalescence, opening
    a new route for droplet manipulation.
