“…37,38 In addition, PVA was connected onto the AgNWs surfaces by forming hydrogen bonds, 39,40 and those PVA and PVP on the surfaces of different AgNWs also formed hydrogen bonds and let the AgNWs undergo self-assemblies and align directionally. 37,41 Besides, the heat transferring and water evaporating during the solidication changed the micro and nano kinetics, let the PVA chains and water molecules move fast and frequently, as stated by Collision theory 42 or Brownian movement, 43 further increased the collides, contacts, and touches between/among the AgNWs. The solidied AgNWs/PVA oen showed shrinking volumes, that these shrinkages on the volumes increased the probability and opportunity of collides, contacts, and touches for AgNWs.…”
