Energy storage material pa66

How are pa66/cf/ago-CNT composites fabricated?

PA66/CF/AGO-CNT composites were fabricated via in situ interfacial polymerization. The interphase-strengthened composites exhibited outstanding mechanical performances with optimal ratio between AGO and CNT. The energy-absrobing ability of the composites have been enhanced by 62% as compared to the control sample.

How does a pa66/cf/ago composite improve thermal stability?

The PA66/CF/AGO composite also showed a high value of 310.7 °C. This indicated that the carbon nanofillers such as AGO and CNTs were attached to the PA66 chain through hydrogen bonding and covalent bonding, which hindered the PA66 chain movement and improved their dispersion state. Therefore, the thermal stability was steadily improved.

What is the absorbed energy of pa66/cf/ago-CNT?

The absorbed energy of PA66/CF/AGO-CNT (8.1 J) was 62% higher than that of the control sample (5 J), which corresponded with the larger energy dissipation caused by the enhanced damping property, as revealed by the DMA results.

Are polyamide 66/carbon fiber composites energy-absrobing?

The energy-absrobing ability of the composites have been enhanced by 62% as compared to the control sample. Polyamide 66 (PA66)/carbon fiber (CF) composites with acyl chloride-functionalized GO (AGO) and carbon nanotubes (CNTs) as hybrid fillers were prepared through in situ interfacial polymerization.

Why do pa66/cf/ago-CNT composites lose 5% weight?

Notably, the 5%-weight-loss temperature decreased with increasing filler concentration from 1.5 to 3.5 mg/mL due to the excessive incorporation of hybrid fillers into the PA66/CF composites, which resulted in agglomeration of the carbon nanofillers. 3.4. Mechanical performance of PA66/CF/AGO-CNT composites

How to calculate XC of PA66?

The degree of crystallinity (Xc) of PA66 was calculated using Eq. (2), as follows: (2) X c = Δ H m 1 - ∅ Δ H 0 m × 100 % where Δ Hm is the enthalpy of PA66 in the composites, Δ H0m (197 J/g) is that of the 100% crystalline PA66 phase, and ∅ is the weight fraction of the carbon nanofillers in the composites.
