摘要：
The present invention relates to a tribochemical method for degradation of polymers in water in presence of metals and carbohydrates, generating nanoplastics in solution. The method comprises stirring a polymeric pellet with carbohydrates in water at a temperature range of 60 ˚C-70 ˚C in a metal vessel for 3-30 days. Stirring generates triboelectric charges on the polymer surface, while carbohydrates-induced corrosion generates metal ions in solution. Interaction of the charged polymer surface with the metal ions results in degradation, generating nanoplastics in solution. The said method could open up greener strategies for polymer degradation.
