AI Technical Summary
Existing antistatic PVC rolls suffer from poor dispersion of conductive fillers, easy agglomeration, which affects antistatic performance and reduces mechanical properties. They cannot function stably in complex environments and have limited application range.
The composite conductive layer structure includes an outer conductive layer, a nano-conductive reinforcement layer, and an inner conductive layer. It utilizes a graphene-modified coating, a three-dimensional mesh structure woven from interlaced silver nanowires and carbon nanotubes, and a metal mesh to form a stable conductive network, thereby enhancing antistatic properties while maintaining mechanical properties.
It achieves stability and uniformity in antistatic properties, improves tensile strength, flexibility and abrasion resistance, expands the range of applications, and meets the needs of complex environments.
