Abstract
Ionic polymer metal composite (IPMC) is one type of artificial muscle technology. This demonstration IPMC based on ionic liquid has the potential to introduce four main aspects of VNOST, such as (1) the characteristics of science and technology, (2) the aim of science and scientific research, (3) the characteristics of scientific knowledge and scientific theories, and (4) the relationship between science and technology. Like the main purpose of VNOST, the introduction of this IPMC based on ionic liquid is not only introducing technology, but introducing the link between technology and science, especially chemistry content. Context-related chemistry content that is at the stage of making chitosan sulfonate membrane involves chemistry contents in the form of solution pH, Lewis base acid theory, sulfonation reaction, substitution reaction, and conductivity. In addition, the stages of the membrane actuation mechanism involve chemistry contents in the form of electrostatic forces, electrolytes, hydrolysis and the relationship of the melting point with the molecular weight.
Keywords: Artificial muscle of Ionic Polymer Metal Composite (IPMC), ionic liquids, demonstrations, pre-service teachers-, dan VNOST (View Nature of Science and Technology).
