Industrial Electrospinning Machine| Roll-To-Roll Twisted Aerogel Yarns with Reinforced Structureand Low Thermal Conductivity

Challenge: Aerogels serve as super thermal insulation materials, but their poor mechanical properties and processability limit applications in textiles. Fiberizing aerogels into one-dimensional forms can improve mechanical performance and processing flexibility, but existing methods suffer from significant fiber performance loss, discontinuous production, and high selectivity.

Approach: Academician Meifang Zhu and Professor Yanhua Cheng from Donghua University utilized two-dimensional nanofiber membranes as media to process aerogel particles into continuous macroscopic yarns based on a roll-to-roll mode. Low-concentration strong nanofibers provided structural support to aerogel particles in a twisted form while maintaining their porous structure.

Innovation 1: Despite aerogel particles occupying up to 78% volume ratio, the aerogel yarn still demonstrated high strength, desirable flexibility and excellent thermal insulation performance.

Innovation 2: Textiles woven with this aerogel yarn were warmer than cashmere. The aerogel textile exhibited extreme stability under temperatures ranging from -196°C to 100°C, mechanical deformation, and even washing conditions.
