Auxetic materials and their potential applications in textiles

TLDR

Auxetic materials, which exhibit a negative Poisson’s ratio and expand laterally when stretched or contract when compressed, possess enhanced properties that make them attractive for specialized applications. This paper reviews recent advances in auxetic materials, covering their properties, structures, and applications. The review discusses auxetic materials’ properties, structures, and their potential textile applications. The review is expected to inform future development of auxetic textile materials.

Abstract

Auxetic materials are a kind of non-conventional materials having negative Poisson’s ratio. They laterally expand when stretched or laterally shrink when compressed. Compared to conventional materials, auxetic materials have a number of enhanced properties that could be very interesting for some special applications. This paper reviews the latest achievements in auxetic materials, including their properties, structures and applications. A special discussion on their potential applications in textiles is also made. It is expected that this review could provide some useful information for the future development of auxetic textile materials.
