Abstract

Due to their broad coverage and long operational duration, as well as their ability to be used as quasi-stationary platforms, stratospheric airships have gained increasing popularity for persistent near-space communication relay, Earth observation, environmental monitoring, and military reconnaissance. Nevertheless, their operational stability is severely threatened by the harsh conditions of the stratosphere, including intense ultraviolet light, ozone exposure, low pressure, extreme temperature variations, and periodic mechanical strain. The envelope coating, as the primary discontinuity between the lifting gas and the external environment, is a determinant of structural integrity, gas retention, thermal control, and operational reliability. This review is a systematic summary of recent developments in intelligent nanocomposite coating materials for airships operating in stratospheric airspace. The practical needs of these coatings, such as mechanical strength, environmental stability, gas protection properties, light structures, and multifunctionality, are initially discussed. Next, representative polymer matrices, multifunctional nanofillers, and new fabrication technologies are presented, with a focus on interface engineering and hierarchical structure design. The smart capabilities of self-healing, self-sensing, stimuli-responsive adaptation, and synergistic performance improvement mechanisms have been extensively examined. Existing uses in envelope protection, thermal control, anti-icing, anti-static dissipation, and structural health monitoring are outlined, and issues related to scalability, durability, cost, and system integration are noted. Lastly, future development trends, including AI-aided materials design, digital twins, self-powered sensing systems, and sustainable multifunctional coatings, are suggested. The intelligent nanocomposite coating is anticipated to transform the development of stratospheric airships by enabling the creation of lightweight, adaptive, and autonomous near-space systems.
