HIGHLIGHTS
- who: Hongxia Li and colleagues from the School of Material Science and Engineering, Harbin Institute of Technology, Harbin, China have published the article: Low Dielectric Constant Polyimide Obtained by Four Kinds of Irradiation Sources, in the Journal: (JOURNAL)
- what: This should be the main reason for the decrease of the dielectric constant.
- how: The results showed that the polymer had good heat resistance and glass transition temperature (Tg ) available at above 400 ◦ C the spiral structure increased the free volume and the dielectric constant was as low as 2.31 . The result showed . . .
