“…The measured thermal conductivity of suspended single layer graphene is around 3000 to 5300 W m −1 K −1 , whose value decreases with increasing number of layers for the suspended sample and approaches very quickly to that of bulk graphite (around 1800 to 2100 W m −1 K −1 ) . However, the thermal conductivity of these carbon‐based nanocomposites is much smaller than the expected value, which therefore has potential applications as thermoelectric materials . CNTs‐ or graphene‐based PANI composites are found to have a relatively low thermal conductivity.…”

“…[84,112,113] However, the thermal conductivity of these carbon-based nanocomposites is much smaller than the expected value, which therefore has potential applications as thermoelectric materials. [114][115][116][117] CNTs-or graphene-based PANI composites [110,118] are found to have a relatively low thermal conductivity. For instance, Wang et al [110] reported the room temperature thermal conductivity of single-walled carbon nanotubes (SWNTs)/PANI composite film around 0.4 W m −1 K −1 for 20-50% weight filling ratio of SWNTs (Figure 6a), although the strong π-π interactions between the PANI and SWNTs induced the PANI molecules to form a highly ordered structure.…”

The demand for flexible conductive materials has motivated many recent studies on conductive polymer–based materials. However, the thermal conductivity of conductive polymers is relatively low, which may lead to serious heat dissipation problems for device applications. This review provides a summary of the fundamental principles for thermal transport in conductive polymers and their composites, and recent advancements in regulating their thermal conductivity. The thermal transport mechanisms in conductive polymer–based materials and up‐to‐date experimental approaches for measuring thermal conductivity are first summarized. Effective approaches for the regulation of thermal conductivity are then discussed. Finally, thermal‐related applications and future perspectives are given for conductive polymers and their composites.

“…The fast gelation process in the constructive regions allows for a rapid holographic patterning while the prolonged gelation in the destructive regions provides longer time for the phase separation [12][13][14]. Nevertheless, despite the amazing progress on the elegant design of new photo-mediated systems [26][27][28][29][30][31][32][33][34][35][36] for a myriad of attractive applications such as sequential polymerization control [29], 3D printing [30], surface grafting [31], and fabricating conductive composites [36], very few efforts have been made to implement such a spatiotemporal control during holography [13]. Peng and co-workers [12,13] disclosed that a "photoinitibitor" with concurrent initiation and inhibition functions was able to exert a precise control over the photopolymerization kinetics and gelation during holographic patterning.…”

Effect of ketyl radical on the structure and performance of holographic polymer/liquid-crystal composites

et al. 2019

Holographic polymer/liquid-crystal composites, which are periodically ordered materials with alternative polymer-rich and liquid-crystal-rich phases, have drawn increasing interest due to their unique capabilities of reconstructing colored three-dimensional (3D) images and enabling the electro-optic response. They are formed via photopolymerization induced phase separation upon exposure to laser interference patterns, where a fast photopolymerization is required to facilitate the holographic patterning. Yet, the fast photopolymerization generally leads to depressed phase separation and it remains challenging to boost the holographic performance via kinetics control. Herein, we disclose that the ketyl radical inhibition is able to significantly boost the phase separation and holographic performance by preventing the proliferated diffusion of initiating radicals from the constructive to the destructive regions. Dramatically depressed phase separation is caused when converting the inhibiting ketyl radical to a new initiating radical, indicating the significance of ketyl radical inhibition when designing high performance holographic polymer composites.Scheme 1 Schematic illustration on the conversion of the ketyl radical with an inhibition function to a new initiating radical and the corresponding ordered structures.Scheme 5 Proposed radical diffusion during holographic photopolymerization.

This review provides a brief summary of the recent research developments in the fabrication and application of conducting polymer nanostructures and their derivatives as electrodes for flexible supercapacitors (SCs). By controlling the nucleation and growth process of polymerization, conducting polymers (CPs) with different nanostructures can be prepared by employing chemical polymerization, electrochemical polymerization and photo-induced polymerization. These CPs (such as polyaniline and polypyrrole) with special nanostructures possess high capacitance, superior rate capability ascribed to large electrochemical surface, and optimal ion diffusion path in the ordered nanostructures.The composites of nano-structured conducting polymer and some conductive flexible substrates (such as carbon nanotube film and graphene film) are proved to be ideal electrode materials for high performance flexible SCs. Furthermore, high N-containing CPs are very prospective for preparing Ndoped carbon materials used as flexible electrodes for flexible SCs. With respect to the extra pseudo-capacitance induced by N atoms and superior stability derived from the conjugated graphitic structure of carbon materials, the obtained flexible SCs based on N-doped carbon materials could achieve high capacitance, high rate performance, and superior cycling stability.
