Anti-rebound of polymer drops




2015.05.18 21:55

Small addition of polymers can greatly affect the dynamics of the impacting droplet. One representative effect is that the rebound of droplets are suppressed. There were several theories to explain this phenomena, and it was found to be the polymer residue which increases the line resistance. The concentration and the molecular weight reciprocally affect the anti-rebound phenomena and we suggest equation which can estimate the rebound of polymer droplet.
