Polymer brush-modified surfaces demonstrated significant friction reduction between nanoscale contacts as revealed through Lateral Force Microscopy (LFM). In this study, the frictional properties between a colloidal particle and a series of chemically different polymer brushes deposited on plastic substrates were studied by colloidal probe LFM.

La modifica delle superfici con polymer brushes ha permesso una significativa riduzione dell'attrito tra contatti su scala nanometrica, come evidenziato attraverso la microscopia a forza laterale (LFM). In questo progetto, è stato indagato l'attrito tra una particella colloidale e una serie di polymer brushes chimicamente diversi tra loro, depositati su superfici polimeriche, mediante LFM con sonda colloidale. I risultati ottenuti forniscono preziose informazioni sul potenziale di un approccio di grafting-to semplice e rapido per rivestire una vasta gamma di materiali plastici e ridurre le loro proprietà di attrito.

Abstract
Polymer brush-modified surfaces demonstrated significant friction reduction between nanoscale contacts as revealed through Lateral Force Microscopy (LFM). In this study, the frictional properties between a colloidal particle and a series of chemically different polymer brushes deposited on plastic substrates were studied by colloidal probe LFM. The results provide valuable insights into the potential of a straightforward grafting-to approach for coating the plastics and enhance their lubrication properties.File | Dimensione | Formato | |
