“…However, the question of formation of SiOC(O)NH (bond between ladder fragment and PU matrix) remains. The presence of such bonds is important for reinforcement of PU matrix by ladder‐like fragment because the chemical bonds between filler and polymer matrix increase the filler effect on mechanical properties 15 . The IR spectroscopy did not allow to answer this question because of the luck of the data about vibration characteristics of SiOC(O)NH unit.…”

In this work, ladder‐like polyphenylsiloxane containing silanol groups was used for modification of polyurethane (PU) based on MDI and polypropylene oxide polyol. The obtained coatings have excellent mechanical performance and adhesion to steel. This improvement was confirmed through a combination of characterization techniques. The tensile strength and strength adhesion to steel increase by more than one order of magnitude when polysiloxane fraction increased from 10 to 50 wt.%. With an increase loading level, the coating transforms from hydrophilic to hydrophobic. The reinforcement effect was motivated by restriction of molecular mobility in PU matrix as was shown by solid‐state 1H NMR spectroscopy and formation of chemical bonds between PU and polysiloxane units.

Carbon fiber-reinforced polymer-matrix composites have been an important research topic due to their high performance and versatility. In this study, we investigated the mechanical, thermal, and electrical properties of short carbon fiberreinforced polypropylene (SCF/PP) composites prepared using the fused deposition modeling (FDM)-3D printing technique. PP was selected as the matrix for 3D printed composites to overcome the processing problems caused by the high content of SCFs. The addition of SCFs also effectively mitigated the warping problem during the PP cooling process. Compared to pure PP, the tensile strength increased by up to 35%, and the bending strength exhibited an approximate 40% enhancement. With increasing SCF content, the thermal conductivity exhibited a linear growth, reaching 0.266 W/(m • K) at 70 °C for the PPCF50 sample, simultaneously demonstrating excellent electrical conductivity. The material also displayed significant potential in electromagnetic protection applications, achieving a maximum shielding effectiveness of 29.8 dB. The texture direction and filling density in 3D printing settings have also been proven to play important roles in adjusting the performance of composite samples. The attempt of this study is beneficial for promoting the widespread application of polyolefin polymers as a consumable matrix material for 3D printed SCF-reinforced composite products.

“…This has been demonstrated in numerous studies. In contrast to random and disordered network structures, oriented nano-arrangement of graphene-based composites has a significant enhancement in conductivity and can effectively reduce the percolation threshold; this phenomenon prevents excessive fillers from affecting the mechanical properties of the composite. – During practical applications, multiple composite materials will inevitably be subjected to bending stresses. As such, it is essential that the material exhibits adequate mechanical properties to withstand these conditions.…”

Graphene is a promising reinforcement for fiber composite materials in flexible wearable applications because of its exceptional conductivity. Researchers have focused on bridging the gap between the intrinsic conductivity of graphene and the macroscopic performance of composite materials. The anisotropy of 2D nanomaterials indicates that their orientation and distribution are crucial factors in determining the macroscopic performance of thin films and bulk materials. Various technologies developed to control the formation of microstructures include electric and magnetic field methods, hot pressing, centrifugation, and freeze-drying. In this study, we prepared flexible graphene/cellulose composite film materials and used magnetic fields to regulate the orientation and distribution of graphene within cellulose paper. Results show that the grid structure of graphene arranged on the composite material produced interconnected conductive paths and reduced the graphene permeation threshold. By giving the conductive layer a higher dielectric constant, we prevented its breakdown as a conductive film. Electroluminescent devices were constructed using graphene/cellulose flexible composite materials and achieved an effective improvement in luminescence performance. Furthermore, directional luminescence was obtained through a microstructure design. This study provides a feasible path for using 2D nanomaterials in high-performance, flexible wearable devices.
