SEM morphologies of the AgNWs/PVC/AgNWs films prepared with different dipping speed and lifting speed by the dip-coating process: a dipping speed = 40 mm/min, lifting speed = 100 mm/min; b dipping speed = 50 mm/min, lifting speed = 100 mm/min; c dipping speed = 60 mm/min, lifting speed = 100 mm/min; d dipping speed = 70 mm/min, lifting speed = 100 mm/min
