Integration of Antifouling and Underwater Sound Absorption Properties into PDMS/MWCNT/SiO2 Coatings. [PDF]

open access: yesBiomimetics (Basel), 2022
Any surface immersed in sea water will suffer from marine fouling, including underwater sound absorption coatings. Traditional underwater sound absorption coatings rely heavily on the use of toxic, biocide-containing paints to combat biofouling. In this paper, an environmentally-friendly nanocomposite with integrated antifouling and underwater sound ...

Recent study progress of underwater sound absorption coating

open access: yesEngineering Reports, 2023
AbstractBased on the recent development of underwater sound absorption coatings, this paper analyzes the evolution of underwater sound absorption coatings from two aspects: traditional structures and metamaterials. The traditional structures are divided into three types: cavity structures, composite structures, and impedance‐matching structures. First,

Multifunctional Integrated Underwater Sound Absorption Materials: A Review

open access: yesApplied Sciences (Switzerland), 2023
Rapid improvements in underwater vehicle technology have led to a significant increase in the demand for underwater sound absorption materials. These materials, unlike their counterparts utilized in air, must have high hydrostatic pressure resistance, corrosion resistance, and other advantageous attributes.

Grating‐like anechoic layer for broadband underwater sound absorption

open access: yesInternational Journal of Mechanical System Dynamics, 2022
AbstractTo address the challenging task of effective sound absorption in the low and broad frequency band for underwater structures, we propose a novel grating‐like anechoic layer by filling rubber blocks and an air backing layer into metallic grating.
