چکیده
Abstract In this work, mussel-inspired surface functionalization of halloysite nanotubes (HNTs) were coated by in situ self-polymerization polydopamine (PDA) to synthesize core-shell structural composites (HNTs@PDA), and then incorporated into polyarylene ether nitrile (PEN) matrix. Due the strong adhesion PDA modification layer formation hydrogen bonds between polar group PEN catechol PDA, dispersion interfacial compatibility HNTs@PDA matrix are improved. The results show that dielectric constant PEN/HNTs@PDA 20 nanocomposites reaches 11.56 (1 kHz), which is 3.2 times pure PEN. addition, after heat treatment, a chemical cross-linking reaction occurred form cross-linked (CPEN) based nanocomposites, further improved thermal stability nanocomposites. T g CPEN/HNTs@PDA 215.5°C, 47.7°C higher than 20. Moreover, constant-temperature coefficient all CPEN less 7 × 10 −4 °C −1 at temperature range 25–180°C. All all, work provides simple environmentally friendly strategy adjust properties polymer-based ceramic pathway for its application as material film capacitors field.

Crosslinked polyarylene ether nitrile film as flexible dielectric materials with ultrahigh thermal stability
Dielectric film with ultrahigh thermal stability based on crosslinked polyarylene ether nitrile is prepared and characterized. The film is obtained by solution-casting of polyarylene ether nitrile terminated phthalonitrile (PEN-Ph) combined with post self-crosslinking at high temperature. The film shows a 5% decomposition temperature over 520 °C and a glass transition temperature (Tg) around 38...
