| Abstract | Soft materials can be found all over the world. Not only can they be found in man-made items, but nature also utilized soft materials such as leaves, muscle, organs, and more. Seeing nature as inspiration, soft materials became the focus of research around the world. Soft materials have the advantage of having many degrees of freedom compared to hard materials. This advantage also comes with its disadvantages as having a high degree of freedom also leads to complex control systems. To resolve this, there are research that aims to develop methods to manipulate soft materials and utilize them. In this study we have fabricated a soft structure based on magnetic Polydimethylsiloxane (PDMS) nanocomposite material. PDMS is a biocompatible polymer material which was modified with magnetic Fe3O4 nanoparticles to make it magnetic in nature. The nanoparticles were characterized by using electron microscopy and x-ray powder diffraction to study the morphological and material properties of the nanoparticles. The nanocomposite was then characterized to understand its mechanical strength using texture analysis testing machine. By controlling the quantity and alignment of the magnetic domains within the nanocomposite, we have made a structure and demonstrated its movement by applying an external magnetic field. |
