超反射奈米涼感布料問世：室外降溫 2°C、生物可降解、可量產

在極端高溫越趨頻繁的氣候時代，全球紡織與戶外裝備產業都面臨新的挑戰：如何讓人體在室外保持涼爽、乾燥並避免熱傷害。來自中國鄭州大學與澳洲南澳大學（UniSA）研究團隊近日提出一項突破性的材料技術，或將重新定義「降溫衣物」的下一個世代。

As extreme heat becomes a defining challenge of the climate crisis, the global textile and outdoor-gear industries are under pressure to deliver materials that help people stay cooler, safer, and more comfortable. A new breakthrough from researchers at Zhengzhou University in China and the University of South Australia (UniSA) may signal the arrival of the next generation of cooling textiles.

這項研究由南澳大學材料科學家馬軍（Jun Ma）教授與鄭州大學副教授潘亞敏（Yamin Pan）領銜，成果發表於《Nano Research》期刊。研究團隊開發出一款能反射96% 太陽光熱能、同時具備高速排汗能力的「PLA/BNNS 生物可降解奈米複合纖維布料」。在戶外實測中，穿著者的皮膚溫度於陽光直射下可降低 2°C，夜間甚至比裸露皮膚低 3.8°C。

Published in Nano Research, the study introduces a biodegradable PLA/BNNS composite fabric that reflects 96% of solar radiation and provides rapid moisture-wicking performance. In field tests, the textile lowered skin temperature by 2°C under direct sunlight and 3.8°C at night, compared with bare skin.

新材料如何降溫？關鍵在「反射熱 + 導熱 + 排汗」三效合一

Cooling through Reflection, Heat Dissipation, and Moisture Control

Traditional cotton traps both heat and sweat, making it unsuitable for extreme heat. The new fabric combines:

傳統棉質布料的缺點是蓄熱、吸濕卻不易散濕，使皮膚悶熱潮濕，更會放大熱浪造成的危害。新型布料採用：

研究團隊以可量產的靜電紡絲技術將 BNNS 均勻嵌入 PLA 纖維中，形成具奈米孔洞的白色結構，使布料：

馬軍教授表示：「在全球熱浪加劇的情況下，戶外工作者、運動員與缺乏空調設備的人都承受更高的熱壓力。我們希望打造一種不需耗能、可自然調節溫度的永續布料。」

戶外工作者、軍警、運動市場將成最大受益者

Using scalable electrospinning, the researchers embedded BNNS within the PLA fiber matrix, creating a nanostructured, highly breathable white textile that offers five times the breathability of cotton.

“The combination of high solar reflectance, radiative cooling, and moisture transport makes the wearer feel significantly cooler and drier,” said UniSA’s Professor Jun Ma. “This is particularly valuable for workers in construction, mining, agriculture, and emergency services - sectors where heat exposure is both a comfort and safety concern.”

A Growing Market for Heat-Resilient Apparel

由於此材料具備降溫與快速排汗性能，研究團隊認為應用前景極為廣泛，包括：

全球熱浪上升讓降溫衣物市場快速擴張。根據 Allied Market Research，全球冷卻纖維布料市場將在 2030 年前突破 40 億美元，年增近 10%。此研究的商轉潛力極強，因其 可大規模生產、材料環保，符合市場對永續機能布料的需求。

The collaboration also highlights how international research partnerships accelerate smart-materials innovation. Lead author Associate Professor Yamin Pan notes that UniSA’s materials expertise was essential for evaluating thermal-transfer and cooling performance.

Beyond comfort, the fabric’s environmentally responsible profile stands out. PLA is derived from renewable biomass and naturally degradable, aligning with global demand for sustainable textiles as fashion and apparel brands work to cut carbon emissions.

永續材料成布料產業下個十年競爭核心

Given the technology’s strong cooling capability, low environmental footprint, and compatibility with mass manufacturing, the textile shows strong commercial potential for:

除了效能，這項布料最大的亮點之一是其材料的環保屬性。PLA 來自可再生資源（如玉米澱粉），能自然分解；BNNS 本身化學穩定且無毒。 在全球時尚產業面臨減碳壓力下，品牌對永續機能布料的採用意願持續上升。

With the cooling-fabric market projected to exceed USD 4 billion by 2030, such innovations are well-positioned to reshape industry standards.

馬軍教授表示，研究團隊將持續探索商業化與大規模製造的可能性：「靜電紡絲技術成本低、擴產容易，能將這款布料推向工業量產，進一步改變下一代降溫衣物的設計。」

Professor Ma says the team is now exploring industrial-scale production: “Electrospinning is cost-effective and easily scalable. With further development, this textile could redefine the next generation of cooling clothing.”
