Abstract

Coatings represent one of the most widely employed strategies for mitigating metal corrosion, yet their long-term performance is often compromised by inherent structural defects and permeability to aggressive species. While traditional filler-reinforced coatings enhance barrier properties and pigmented coatings systems can additionally provide active protection, however, in an uncontrolled way, recent advances in smart materials have enabled the development of self-healing systems capable of providing active corrosion inhibition exactly when needed. This review comprehensively examines the multifaceted role of silica-based fillers—spanning pristine, modified, and container-type structures—in the design of high-performance corrosion protection coatings. We comprehensively analyze coating fabrication technologies, the barrier-enhancing mechanisms of silica fillers, and advanced strategies for synthesizing and functionalizing silica micro/nano-containers to achieve stimuli-responsive release. Special emphasis is placed on “gatekeeper” systems that enable on-demand, localized delivery of inhibitors in response to corrosion-related triggers. By integrating discussions on both physical barrier enhancement and active self-healing functionality, this work provides a unified perspective on silica-based coating design. Furthermore, we critically assess current challenges, including filler dispersion, release kinetics control, and scalability, and propose future research directions aimed at advancing the practical application of intelligent silica-containing coatings for extended metallic structure durability.

含硅防腐蚀涂层

涂层是缓解金属腐蚀最广泛使用的策略之一，但其长期性能往往受到固有结构缺陷和对侵略性物质的渗透性的影响。虽然传统的填料增强涂层增强了屏障性能，而色素涂层系统可以额外提供主动保护，但是，以一种不受控制的方式，智能材料的最新进展使得能够在需要时提供主动腐蚀抑制的自修复系统的开发成为可能。本文全面研究了硅基填料在高性能防腐涂料设计中的多方面作用，包括原始结构、改性结构和容器型结构。我们全面分析了涂层制造技术，二氧化硅填料的屏障增强机制，以及合成和功能化二氧化硅微/纳米容器以实现刺激响应释放的先进策略。特别强调的是“看门人”系统，该系统能够根据腐蚀相关的触发因素，按需、本地化地交付抑制剂。通过整合物理屏障增强和主动自愈功能的讨论，这项工作为硅基涂层设计提供了统一的视角。此外，我们批判性地评估了当前的挑战，包括填料分散，释放动力学控制和可扩展性，并提出了未来的研究方向，旨在推进智能含硅涂层的实际应用，以延长金属结构的耐久性。

期刊介绍： Progress in Materials Science is a journal that publishes authoritative and critical reviews of recent advances in the science of materials. The focus of the journal is on the fundamental aspects of materials science, particularly those concerning microstructure and nanostructure and their relationship to properties. Emphasis is also placed on the thermodynamics, kinetics, mechanisms, and modeling of processes within materials, as well as the understanding of material properties in engineering and other applications. The journal welcomes reviews from authors who are active leaders in the field of materials science and have a strong scientific track record. Materials of interest include metallic, ceramic, polymeric, biological, medical, and composite materials in all forms. Manuscripts submitted to Progress in Materials Science are generally longer than those found in other research journals. While the focus is on invited reviews, interested authors may submit a proposal for consideration. Non-invited manuscripts are required to be preceded by the submission of a proposal. Authors publishing in Progress in Materials Science have the option to publish their research via subscription or open access. Open access publication requires the author or research funder to meet a publication fee (APC). Abstracting and indexing services for Progress in Materials Science include Current Contents, Science Citation Index Expanded, Materials Science Citation Index, Chemical Abstracts, Engineering Index, INSPEC, and Scopus.
