摘要

可穿戴光热材料能够捕捉自然界中的光能并将其转化为热能,这对于柔性户外运动至关重要。然而,传统的柔性光热膜比表面积低,限制了光热能力的最大化,而电纺膜结构松散,限制了可穿戴材料的耐用性。本文首先通过溶剂诱导重结晶法制备了超薄纳米结构烛烟/多壁碳纳米管/聚(L-乳酸)(CS/MWCNTs/PLLA)光热膜。首次实现了具有高比表面积的白细胞膜状纳米皱纹,并表现出最佳的光吸收性能。溶剂诱导重结晶还使膜具有高强度和耐久性。同时,该膜还呈现出双面异色特征,并在厚膜和薄膜的情况下分别呈现出透明性,显示出卓越的时尚性。通过新型溶剂诱导重结晶技术制备的纳米皱纹光热膜具有高柔韧性、时尚性、强度和光热特性,在户外保暖和冬季运动服方面具有巨大潜力。

Reinforced nanowrinkle electrospun photothermal membranes via solvent-induced recrystallization

Wearable photothermal materials can capture light energy in nature and convert it into heat energy, which is critical for flexible outdoor sports. However, the conventional flexible photothermal membranes with low specific surface area restrict the maximum photothermal capability, and loose structure of electrospun membrane limits durability of wearable materials. Here, an ultrathin nanostructure candle soot/multi-walled carbon nanotubes/poly (L-lactic acid) (CS/MWCNTs/PLLA) photothermal membrane is first prepared via solvent-induced recrystallization. The white blood cell membrane-like nanowrinkles with high specific surface area are achieved for the first time and exhibit optimal light absorption. The solvent-induced recrystallization also enables the membrane to realize large strength and durability. Meanwhile, the membranes also show two-sided heterochromatic features and transparency in thick and thin situations, respectively, suggesting outstanding fashionability. The nano-wrinkled photothermal membranes by novel solvent-induced recrystallization show high flexibility, fashionability, strength, and photothermal characteristics, which have huge potential for outdoor warmth and winter sportswear.
