  Abstract

The effects of hydrophilic and hydrophobic surface properties of poly(imide) (PI) films on the adhesion and removal of particles to/from the films were investigated as functions of ionic strength, surfactant concentration, and surfactant type. An O2 plasma treatment and a two-step O2+CHF3 plasma treatment were used to impart hydrophilicity and hydrophobicity to the PI film, respectively. The contact angle of the PI film treated with O2 plasma decreased with increasing treatment time, while that of PI film treated with O2+CHF3 plasma increased. Further, surfactant adsorption was higher in the PI film treated with O2+CHF3 plasma than in the film treated with O2 plasma. Generally, the effects of hydrophilic and hydrophobic surface properties of the films on the adhesion and removal of particles were minimal, while the influence of surfactant concentration on the adhesion and removal of particles was stronger than the effect of other solution parameters. The adhesion of α-Fe2O3 particles to the films and their removal from the films were well correlated with the contact angle and the surfactant adsorption.
