Evolution, Prospects, and Predicaments of Polymers in Marine Applications: A Potential Successor to Traditional Materials
Summary
This review examines the growing use of polymer materials in marine applications such as boat hulls, offshore structures, and underwater equipment, where their light weight and corrosion resistance offer advantages over traditional metals. Researchers also discuss the environmental downsides, including the potential release of microplastics and chemicals as these materials degrade in seawater. The study calls for developing more sustainable polymer formulations that balance performance with reduced environmental impact.
Polymers are ideal solutions for architects and constructors in the marine field who require materials that can achieve light and stable structures owing to their unique advantages. For instance, they possess a high strength-to-weight ratio, high wear resistance and fatigue strength, resistance to corrosion, ease of fabrication, and superior vibration damping behavior. These properties make polymers well suited for marine-based applications. However, polymers have their disadvantages, such as contributing to plastic pollution, which has a detrimental impact on the environment. In recent times, various concurrent methods have been employed to advance the future of polymers. This review explores (i) an overall view of polymers used in marine industries, (ii) a focus on reducing plastic wastage, (iii) challenges involved in recycling polymers and ensuring their sustainability, and (iv) the development of renewable plastics.
