In this study, two phosphorus-carbon (P-C) composites with well-controlled compositions and nanostructures of P and C have been developed: P@YP composite with P confined within porous structure of YP-80F carbon and P@CNT with unconfined P deposited on the surface of carbon nanotube.
The well-designed nanostructured P-C composite with P confined within porous structure of carbon is demonstrated to greatly enhance the electrochemical performance, leading to promising long-term cycling stability.

To characterize the effect of the composite with Super P, the electrochemical performance of the pristine and Super P composite samples was evaluated and compared.
Mehta and co-workers had successfully fabricated a device with ultrafast response and recovery of hydrogen sensing based on graphene composite layers with Pd and Pt nanoparticles dispersed on graphene layers [143].
The Mann–Whitney-Wilcoxon test shows that the E2SFCA measure is greater in median than the optimization composite measure with p-values less than 10−6 for small and medium counties, and 2.02 × 10−2 for large counties.
In contrast, the P@CNT composite with unconfined P nanostructures shows a rapid capacity decay with capacity retention of ~ 40.6% after 100 cycles, most likely due to unstable SEI during cycling, caused by the large volume changes of unconfined P in the P@CNT composite.
Composite with Nafion®, P(An-co-OAP) and PAn films, keep their redox activity in chloride-containing acid solutions providing almost a complete protection of the SS substrate against pitting corrosion.

After post-treatments, such as immersion in hydrazine solutions and polyethyleneimine-infiltration, the thermoelectric properties of the CNT/PEDOT PSS composite fibers were optimized, with p- and n-type power factors of 83.2 ± 6.4 and 113 ± 25 μW m−1 K−2, respectively.
For the composites with low SRG loadings (p ≤ 0.3 vol.%), σ(f) increases almost linearly with frequency, which is a typical characteristic of insulating materials.
