A novel strategy for synthesizing an antistatic epoxy composite was carried out. Pre-embedded antistatic melamine foam was first synthesized and then used to prepare an antistatic epoxy composite. Azidized polyacrylic acid (APAA) was grafted onto multiwalled carbon nanotubes (APAA-MWCNTs) by direct functional modification of the MWCNT sidewalls. Melamine was then covalently bonded to MWCNTs (MA-APAA-MWCNTs). The chemical structure of MA-APAA-MWCNTs was characterized by FT-IR spectroscopy, EDS, TGA, Raman spectroscopy, and TEM. As an antistatic agent, MA-APAA-MWCNTs utilized the functional groups of the surface to participate in the formation of melamine foam by reaction with paraformaldehyde. The surface resistivity was decreased to 3.6 × 10⁸ Ω sq⁻¹ when the loading of MWCNTs was 2.4 kg m⁻³. The prepared antistatic foam at different compression ratios was immersed in epoxy resin, which was then cured. When the compression ratio reached 40%, the surface resistivity and volume resistivity, respectively, reached 1.05 × 10⁸ Ω sq⁻¹ and 3.5 × 10⁸ Ω cm, thereby achieving an antistatic effect.

多壁碳纳米管功能化三聚氰胺泡沫抗静电环氧复合材料的制备与表征

进行了一种合成抗静电环氧复合材料的新策略。首先合成了预埋式抗静电三聚氰胺泡沫，然后用于制备抗静电环氧复合材料。通过对 MWCNT 侧壁进行直接功能改性，将叠氮化聚丙烯酸 (APAA) 接枝到多壁碳纳米管 (APAA-MWCNT) 上。然后将三聚氰胺共价键合到 MWCNT (MA-APAA-MWCNT)。MA-APAA-MWCNTs的化学结构通过FT-IR光谱、EDS、TGA、拉曼光谱和TEM进行了表征。作为抗静电剂，MA-APAA-MWCNTs利用表面的官能团通过与多聚甲醛反应参与形成三聚氰胺泡沫。表面电阻率降至3.6 × 10 ⁸ Ω sq ^-1当 MWCNTs 的负载为 2.4 kg m ^-3时。将制备的不同压缩比的抗静电泡沫浸入环氧树脂中，然后固化。当压缩比达到40%时，表面电阻率和体积电阻率分别达到1.05×10 ⁸ Ω sq ^-1和3.5×10 ⁸ Ω cm，从而达到抗静电效果。
