Conductive Polyacetal Composition with Good Flowability and Processability for Electric Heating Tubes

Conductive Polyacetal Composition with Good Flowability and Processability for Electric Heating Tubes

But the efforts did not stop, and all technological advancements were developed through perseverance.

Nowadays, some people have developed conductive acetal composites with improved toughness, softness, good flowability, and processability using the method of doping conductive substances mentioned above. This solves the previous shortcomings of poor fluidity and loss of plastic properties after adding conductive powder. It should be said to be an important progress.

This type of polymer includes formaldehyde polymer, elastic polyurethane, and conductive carbon black, The key is that this carbon black has a lower structural value (absorption) and larger particle size compared to the carbon black used in these compositions so far The further development of low surface is the development of directly conductive polymers. This conductive plastic was accidentally discovered during experimental operation errors. That was one day in 1970, when Professor Shirakawa of Tsukuba University in Japan was guiding students in an experiment to produce polyacetylene using ethylene gas, they mistakenly added a catalyst 1000 times more than the actual amount needed to the reagent, and the result was not the expected black polyacetylene powder containing carbon based long chains It is a shiny silver plastic film. Later, when studying this plastic film with two Americans, Shirakawa found that adding iodine to the film could actually conduct electricity, and the conductivity increased by 30 million times. Nevertheless, its conductivity is only equivalent to that of metal lead, or IX of copper and silver. Afterwards, people began to study this conductive plastic.

Subsequent studies showed that, in addition to polyacetylene, some high molecular polymers such as polyphenylene sulfide, polypyrrole, Polythiophene and polythiazole can also become conductive plastics after adding dopants. On this basis, people have made a batch of polymers with conductivity equivalent to silver and copper, and called them organic metals or synthetic metals.

With the rapid development of modern industrial technology, especially the astonishing progress of modern electronic technology represented by the international internet and global mobile communication, it is believed that a new generation of directly plastic plated products will be developed, as this is already an urgent market demand. This need is a powerful driving force for technological progress.
