Friction Reduction by Grafting PHEMA onto Fe۳O۴-PDMS Nanocomposite

Magnetic polymer nanocomposites can respond to changes in magnetic fields, making them suitable for soft robotapplications. These robots are crucial for reducing surgical invasiveness and shortening hospital stays. However,the high surface friction of poly(dimethylsiloxane) (PDMS) can cause tissue damage and hinder robot movement.In this work, magnetic Fe۳O۴ particles were synthesized and their surface were modified to improve dispersionwithin the PDMS matrix. To reduce the surface friction of PDMS/Fe۳O۴ composite, poly(۲-hydroxyethylmethacrylate) was grafted onto the surface of PDMS/Fe۳O۴ composite by applying the UV/ozone irradiation.
