The progress of design fabrication and performance of thermal conductive polymer composites was reviewed in three directions in this work, including the introduction of single filler, hybrid fillers and complex multiphase structures.

Polyisothiourea is an interesting polymer to potentially exhibit numerious properties. Herein we report the first facile synthesis of polyisothioureas via alternating copolymerization of aziridines and isothiocayanates. Mediated by the catalytic system of phosphazene superbases/alcohol, a broad scope of aziridines and isothiocayanates could be transformed into well-defined polyisothioureas (11 examples).

The 3D-printed RSF-hydroxyapatite composite materials that were prepared through a two-step technique by integrating 3D printing technology and ALP-induced biomimetic mineralization, demonstrated a promising bone substitute material with intricate structure, adjustable compression modulus of megapascal grade and variable hydroxyapatite content.

Thiophene with siloxane-functionalized side chain unit was synthesized and introduced into polymer PM6 to fine-tune morphology of the active layer of OSCs and obtain outstanding J_SC. The PM6-SiO-10:Y6 active layer exhibits the most appropriate phase separation morphology and obtained the PCE of 16.69%, which is one of the highest value for siloxane-functionalized polymer-based binary OSCs.

The ZrO₂ particles were decorated with amino group utilizing AMEO, which were applied as dielectric filler to enhance the dielectric property of PEI. The composites containing ZrO₂-AMEO exhibit high breakdown strength and improved dielectric constant simultaneously, showing excellent energy storage performance at elevated temperatures.

Green ion-conducting membranes based on bacterial cellulose nanofibers with grafted acrylic copolymer was elaborated. High ion mobility and low activation energy of conductivity of prepared membrane allow supercapacitor cell to operate at an ultra-high current density.

EbP with long PP blocks forms an outer shell for the rubber particles,which reduces the interfacial tension between the rubber and the PP matrix, resulting to smaller particle sizes and more effective toughening.

In this paper, the thermal impedance of SR composites loaded with different levels of hexagonal boron nitride as TIMs was elaborated. It is found that the thermal impedance of the SR composites depends on the thermal conductivity, contact resistance and BLT. Besides, the elastic modulus and surface roughness of the SR composites increased with the increase of hexagonal boron nitride content, indicating that the conformity was reduced.

This study simulated simultaneous bulk- and surface-initiated polymerizations and confirmed that the equivalent assumption adopted in experiments is invalid. The heterogeneous stochastic reaction model provided validate information on properties like molecular weight distribution. It provides a new aspect to better understand the mechanism of surface-initiated polymerization via heterogeneous reaction environment.

A relatively continuous proton transport channel is formed between Nafion polymer and Ti₃C₂T_x monomer in Nafion/Ti₃C₂T_x composite membrane. At the higher hydration level, high proton conductivity and high water mobility are achieved.

Moderately semiflexible chains result in a local minimum free energy at the domain center of the lamellar microphase, which demonstrates the ability of tuning of the particle distribution in polymer microphases by chain flexibility.

The nanoparticles at the ends can retard the polymer motion and influence the rheological behavior, where the moduli are less dependent on the frequency as the polymer chain shortens or the nanoparticle becomes large.

Brief summary: We present a theoretical analysis of the mean detachment time of a specific link under spherical confinement using the MFPT technique and demonstrate that spherical confinement leads to a reduction in the conformational entropy of polymers, resulting in entropic forces that accelerate the detachment of polymers from confinement surfaces.
