Document Type and Number:
WIPO Patent Application WO/2024/045654
Kind Code:
A1
Abstract:
A purification system and purification method for metal nanowires. The purification system comprises a storage system (100), a multi-stage purification system, and a control system (800); the storage system (100) consists of a plurality of mutually independent storage tanks (110), and the multi-stage purification system consists of a primary purification device (300), a secondary purification device (400) and a tertiary purification device (600) which are connected in sequence; a filter membrane is provided in the primary purification device (300), a spray head is provided in the secondary purification device (400), the tertiary purification device (600) is formed by a microfluidic purification tower, and a plurality of glass bead purification columns (610) and a plurality of microfluidic chip purification columns (620) are arranged in series in the microfluidic purification tower; and the control system (800) controls the storage system (100) to convey materials to the multi-stage purification system and among the purification devices at all stages in the multi-stage purification system. The purification system uses multi-stage purification, such that the purification speed can be increased to the maximum extent, the purification quality is ensured, and purified metal nanowires having relatively low impurity content are obtained.
