京都大学综合细胞材料科学研究所（iCeMS）研究团队与东京都立大学、东华大学合作，开发出一种受自然启发的泡沫材料，通过微孔结构散射光线实现亮白效果，无需使用钛白粉或PFAS等化学物质。1该材料采用深层泡沫光刻技术制造，工艺流程为使聚合物在光照下分解成小分子片段，随后用温和溶剂处理使其膨胀，最终形成微孔网络结构。1
这一创新材料具有疏水性能，可达20,000 DPI的超高分辨率，已被证明可应用于聚合物膜和纺织品。1相关研究成果已发表于《自然》杂志。1该材料提供了一种更可持续的替代方案。1
Researchers at Kyoto University's Institute for Integrated Cell-Material Sciences (iCeMS) have developed a foam-based material that achieves bright whiteness through light scattering in microscopic pores, eliminating the need for titanium dioxide or other chemical additives.1 The team, working in collaboration with Tokyo Metropolitan University and Donghua University, employed a technique called deep foam photolithography to engineer the material's structure.1
The manufacturing process begins with polymers exposed to light, which causes them to break down into smaller molecular fragments.1 These fragments are then treated with mild solvents that cause the material to expand, creating a network of micropores designed to scatter light effectively.1 The resulting material exhibits both exceptional whiteness and water-repellent properties, achieving resolution levels up to 20,000 DPI.1 The innovation offers a more sustainable alternative to conventional whitening agents, as it requires no titanium dioxide (TiO2) or per- and polyfluoroalkyl substances (PFAS).1
The research demonstrates potential applications for this material in polymer films and textiles, providing an environmentally friendlier approach to achieving bright white finishes.1 The findings were published in Nature on September 10, 2026.1
