摘要
随着全球塑料制品使用量的急剧增加,微塑料(Microplastics,MPs)污染已成为全球环境问题。然而,当前微塑料检测领域面临一个关键挑战:缺乏尺寸精确可控的标准物质(Reference Material,RM),严重制约了检测结果的准确性、可重复性和可比性,也限制了对微塑料污染的全面评估。其中,纤维状标准物质因其独特的形貌、结构和性能,在材料科学、生物医学、环境科学等领域具有重要的研究价值。自组装作为一种高效、可控的制备方法,在纤维状标准物质的制备中展现出巨大的潜力。因此,对近年来通过自组装方法制备纤维状物质的研究进展进行了综述。通过该方法制备的纤维形貌及尺寸精确可控,可以作为纤维状微塑料的理想标准物质,希望为纤维状微塑料标准物质的开发与应用提供新的思路,推动微塑料检测技术的标准化与精准化发展。
The sharp increase in global plastic product utilization has rendered microplastic(MP)pollution a global environmental concern.Presently,the microplastic detection field encounters a crucial challenge:the absence of standard reference materials(RMs)with accurately controlled morphology and dimensions,which strictly constrains the accuracy,reproducibility,and comparability of detection outcomes and impedes a comprehensive evaluation of microplastic pollution.In particular,fibrillar RMs possess substantial application value in materials science,biomedicine,and environmental science owing to their distinctive morphology,structure,and properties.Precise and controllable self-assembly has been shown to be an effective approach for fabricating fibrillar nano-or micromaterials with well-controlled morphology and dimensions.This paper overviews the latest progress in precise and controllable self-assembly strategies for preparing fibrillar substances that could potentially function as ideal RMs for fibrillar microplastics.The objective of this work is to offer novel perspectives for the development and applications of fibrillar microplastic RMs,potentially promoting the standardization and precision of microplastic detection technologies.
