摘要

太阳能驱动的海水淡化技术在解决全球淡水短缺方面拥有巨大的潜力，然而，长时间工作后的蒸发器普遍存在难回收与难降解的问题，严重影响技术的可持续应用能力. 受纸可回收再利用和中国传统折纸工艺的启发，以浒苔纤维素为主要材料混合纸浆纤维制备了一种可回收的折纸蒸发器，引入石墨烯微片以增强其光热转换能力. 在1个太阳光照强度下，蒸发器实现了2.20 kg·m

Abstract

Solar-driven desalination holds significant potential for addressing global freshwater shortages. However

evaporators after prolonged operation commonly face challenges related to difficulty in recycling and degradation

which severely impacts the sustainable application of this technology. Inspired by paper recyclability and the traditional Chinese origami techniques

a recyclable origami-style evaporator was prepared using

Enteromorpha prolifera

cellulose as the main material mixed with pulp fibers

and graphene nanoplatelets were introduced to enhance its photothermal conversion performance. Under 1.0 kW·m

-2

illumination

the evaporator achieved an average evaporation rate of 2.20 kg·m

-2

·h

-1

. Outdoor experimental results demonstrated its effective removal capability for typical ions in seawater

including K

and Mg

with a removal rate exceeding 99%. After recycling and re-preparation

the regenerated evaporator maintained an evaporation rate of 1.95 kg·m

-2

·h

-1

. This work not only provides novel structural inspiration for efficient desalination but also offers a

sustainable solution to evaporator recyclability and the environmental issue of

Enteromorpha prolifera

blooms along the Chinese coastline.
