Title: Transformable Biomimetic Liquid Metal Chameleon,
Abstract: Liquid metal (LM) is of current core interest for a wide variety of newly
emerging areas. However, the functional materials thus made so far by LM only
could display a single silver-white appearance. Here in this study, the new
conceptual colorful LM marbles working like transformable biomimetic chameleons
were proposed and fabricated from LM droplets through encasing them with
fluorescent nano-particles. We demonstrated that this unique LM marble can be
manipulated into various stable magnificent appearances as one desires. And it
can also splitt and merge among different colors. Such multifunctional LM
chameleon is capable of responding to the outside electric-stimulus and
realizing shape transformation and discoloration behaviors as well. Further
more, the electric-stimuli has been disclosed to be an easy going way to
trigger the release of nano/micro-particles from the LM. The present
fluorescent biomimetic liquid metal chameleon is expected to offer important
opportunities for diverse unconventional applications, especially in a wide
variety of functional smart material and color changeable soft robot areas.
