摘要:
Metal nanoparticle-polymer composites, a method of manufacturing the same, and a polymer actuator using the same are provided. The method includes synthesizing an organometallic compound as a precursor of metal nanoparticles, preparing a solution mixture containing the organometallic compound and a polymer, and drying and annealing the solution mixture to generate the metal nanoparticle-polymer composite including metal nanoparticles. Thus, highly efficient metal nanoparticle-polymer composite materials may be manufactured with a uniform distribution without synthesizing nanoparticles.

Provided are a surface-coated polymer actuator and a method of preparing the same. The polymer actuator includes an ionic conductive polymer membrane, metal electrodes formed on both surfaces of the ionic conductive polymer membrane, and coating layers formed on both the surfaces of the metal electrodes.By coating the surfaces of the metal electrodes of the polymer actuator, the leakage of solvent from the electrode surfaces due to an inner pressure, which is caused by the solvent's flow due to an electrical stimulus when the actuator is operated, can be prevented and thus the displacement and drivability of the polymer actuator can be improved.

A polymer actuator containing graphene and a method of preparing the same are provided. The polymer actuator includes an ion-conductive polymer membrane, a metal electrode disposed on both surfaces of the ion-conductive polymer membrane, and graphene dispersed within the ion-conductive polymer membrane. As the graphene is dispersed within the polymer membrane, reverse ion migration due to an osmotic pressure occurring after solvent migration caused by electrostimulation in operation of the actuator can be prevented, and thus drivability of the polymer actuator can be improved.
摘要:
Provided is a method of fabricating a nanoimprint mold which can form sub-100 nm fine pattern structures. The method includes forming patterns on a first substrate using an E-beam lithography (EBL) process, and transferring the patterns formed on the first substrate to a second substrate using a nanoimprint lithography (NIL) process to complete an NIL mold. Accordingly, the method can easily fabricate the nanoimprint mold at low costs on a quartz or glass substrate, which is not suitable for an EBL process to produce sub-100 nm patterns, by utilizing the advantages of the EBL process with a resolution of tens of nanometers.
