We investigate by means of continuum percolation theory and Monte Carlo simulations how spontaneous uniaxial symmetry breaking affects geometric percolation in dispersions of hard rodlike particles. If the particle aspect ratio exceeds about twenty, percolation in the nematic phase can be lost upon adding particles to the dispersion. This contrasts with percolation in the isotropic phase, where a minimum particle loading is always required to obtain system-spanning clusters. For sufficiently short rods, percolation in the uniaxial nematic mimics that of the isotropic phase, where the addition of particles always aids percolation. For aspect ratios between twenty and infinity, but not including infinity, we find re-entrance behavior: percolation in the low-density nematic may be lost upon increasing the amount of nanofillers but can be re-gained by the addition of even more particles to the suspension. Our simulation results for aspect ratios of 5, 10, 20, 50 and 100 strongly support our theoretical predictions, with almost quantitative agreement. We show that a new closure of the connectedness Ornstein-Zernike equation, inspired by Scaled Particle Theory, is more accurate than the Lee-Parsons closure that effectively describes the impact of many-body direct contacts.

“…While the structure‐property relationships of composite interfaces play a role in many different fields, not all could be evaluated in this overview. Many other reviews have been conducted on the properties that are the result of composite interfaces, including fiber reinforced plastic composites, thermal, electrical, and mechanical polymer properties, and dynamic mechanical properties of polymers . There have been prior reviews of the literature for sensing platforms, including ionic polymer and conductor properties for biomimetic sensors, electronic noses for gas sensing, and wearable strain sensors .…”

With haptic and pressure sensor manufacturing in the US totaling $US 1.6 billion in annual revenue—with 2% annual projected growth from 2018 to 2023—and tactical and service clothing manufacturing in the US totaling $US 242.9 million in annual revenue, the potential of advanced wearables continues to grow. As many fields tend toward miniaturized technologies in the modern age, many recent developments have been made for wearable platforms. Within the broad area of wearable platforms, there are many specific applications to consider, such as motion sensing, biomarker detection, monitoring of environmental pollutants, haptic sensors, enhanced soft robotics, and improving the safeguarding capabilities of armor. For these applications, the interfacial phenomena occurring between the continuous and discrete phases within the composite material are responsible for the device's response and bulk properties. Understanding these phenomena at the composite interfaces of the system allows for finer tuning of morphological, electromechanical, and other bulk properties, as well as the optimization of the wearable's output—in terms of the applications targeted. Control over these advanced composite materials is paramount in personalized health‐care systems, advanced defense technologies, commercial wearables. Recent advances on composite interfaces for wearable platforms are discussed, along with trends and an outlook of the field.

“…Some scholars had also investigated the impact of deinking methods of waste newspapers on the properties of composite materials [24]. In addition, the interface between the fiber and the matrix is an important factor affecting the properties of the polymer composite [25,26]. The interaction between the hydrophilic fiber and the matrix is usually limited, while the matrix is usually hydrophobic, which leads to poor interfacial adhesion, limiting mechanical properties and affecting long-term performance at the same time.…”

Waste newspaper are currently used in a single way and have low utilization rates. In this paper, the optimal process of preparing environmentally friendly layered composites by using waste newspaper combined with polypropylene film lamination was studied. The effects of hot-pressing temperature, hot-pressing time and paper content on the properties of the composites were analyzed. The results showed that under the process conditions of hot-pressing temperature 180 °C, compression time 20 min and paper content 66.7%, the obtained composite material had a flexural strength of 126 MPa, a tensile strength of 95 MPa, an impact strength of 5.3 kJ/m2 and a water absorption thickness expansion ratio of 3.2%. Tensile performance increased by 164% compared to the original waste newspaper. Compared to our previous work, the hot processing time had been cut in half and costs were lower. In terms of creep properties, the unrecoverable strain rate was reduced by 57.5% compared to pure polypropylene. The results show that the material can maintain excellent flexural strength, tensile strength and water absorption performance while making good use of waste newspaper.
