“…The dopamine served as a surfactant to stabilize the EGaIn nanodroplets in water. Since dopamine tends to self-polymerize and then form a thin PDA coating on various surfaces under alkaline conditions (pH > 7.5) without premodification, the weak alkaline environment (PH > 8.5) provided by Tris base facilitated the formation of the PDA coating on the EGaIn nanodroplets [ 39 , 40 , 41 , 42 ]. The stabilization effect of the PDA coating on the EGaIn nanodroplet can be directly observed from Figure 1 b–d.…”

Given the thermal management problem aroused by increasing power densities of electronic components in the system, graphene-based papers have raised considerable interest for applications as thermal interface materials (TIMs) to solve interfacial heat transfer issues. Significant research efforts have focused on enhancing the through-plane thermal conductivity of graphene paper; however, for practical thermal management applications, reducing the thermal contact resistance between graphene paper and the mating surface is also a challenge to be addressed. Here, a strategy aimed at reducing the thermal contact resistance between graphene paper and the mating surface to realize enhanced heat dissipation was demonstrated. For this, graphene paper was decorated with polydopamine EGaIn nanocapsules using a facile dip-coating process. In practical TIM application, there was a decrease in the thermal contact resistance between the TIMs and mating surface after decoration (from 46 to 15 K mm2 W−1), which enabled the decorated paper to realize a 26% enhancement of cooling efficiency compared with the case without decoration. This demonstrated that this method is a promising route to enhance the heat dissipation capacity of graphene-based TIMs for practical electronic cooling applications.

“…Some of the drawbacks of the PBO fibre include moisture absorption, smooth surface and surface inertness. 6,7 The moisture absorption factor of the fibre can be mitigated by reinforcing it in a polymer, but this process requires the fibre to interact with the matrix. Surface modification has been considered as a method to enhance the surface properties to ensure good interaction between the PBO fibre and the matrix by the introduction of sufficient functional groups on the surface of the naturally inert fibre.…”

“…Several modification techniques to enhance the PBO fibre-matrix interfacial strength by improving the surfacewettability, roughness, free energy or functionalisation have been studied by various researchers. 7 Wu and Shyng 8 modified the surface of PBO fibre by treatment with methane-sulphonic acid. The results showed a considerable increase of ILSS in the PBO/epoxy composite prepared post-treatment.…”

The study involves the processing of a novel poly [1, 4-phenylene-cis-benzobisoxazole] (PBO) fibre reinforced high-temperature thermoplastic composite with polyaryletherketone (PAEK) as the matrix. The PBO fibre and the PAEK film surface was modified using the method of argon and nitrogen plasma treatment. The investigation primarily focuses on evaluating the tensile properties of the fabricated laminates and correlating it with the effect of plasma treatment, surface characteristics, and its fracture surface. A 5% decrease in tensile strength was observed post argon plasma treatment while a 27% increase in strength was observed post nitrogen plasma treatment. The morphology of the failure surface was investigated by scanning electron microscopy and an interfacial failure was observed. Furthermore, the effect of plasma on the wettability of PBO fibres and PAEK film surface was confirmed by the Dynamic Contact Angle analysis and sessile drop method respectively. FTIR spectral analysis was done to investigate the effect of plasma treatment on the chemical structure on the surface. The results of the wettability study showed that the argon plasma treatment of the fibre surface increased its hydrophobicity while nitrogen plasma treatment resulted in the reduction of contact angle.

“…Not only do polymer matrix composites have attractive and competitive roles in aerospace industries but also lately they have been inserted into the transmission of electromagnetic waves and protective antenna [ 34 ]. These types of polymers, matrix reinforced with other advanced fibers such as PBO fibers [ 35 ], but these types of fiber may need a special coating to increase adhesiveness at the interfacial interface by the cyanate ester polymer [ 36 ].…”

Reinforced composite materials have many applications in the aerospace, marine, and petroleum industries. Glass fiber-reinforced pipes are of considerable importance as pressurized vessels, infrastructure materials, and petroleum wastewater pipelines. The stress intensity factor due to through-thickness discontinuities is a major parameter in fracture mechanics to understand the failure mechanisms in glass fiber-composite pipes. The stress intensity factor is calculated for a composite cylinder subjected to internal pressure using the linear extended finite element method based on the law of energy release evaluation of surface damage. The analytical model needs two material properties; they are the tensile strength and the fracture toughness; therefore, a standard tensile test was carried out on a standard specimen taken from the pipe’s wall thickness. Moreover, the compact tension test specimen was manufactured from the pipe’s wall thickness to obtain the fracture toughness. The average tensile strength was measured as 21.5 MPa with a standard deviation of 5.59 MPa, moreover, the average Young’s modulus was measured as 32.75 GPa with a standard deviation of 6.64 GPa. The fracture toughness was measured as 2322 (MPa √m) with a standard deviation of 142.5 (MPa √m), whereas the average surface release energy (GIC) was 153.6 kJ/m2 with a standard deviation of 22.53 kJ/m2. A valuable design equation was extracted from the finite element model to measure the effect of cracks on the hoop stress of the cylinder wall thickness based on a nonlinear model. Moreover, an acceptable equation was used to calculate the correction and shape factor of a cylinder with movable and unmovable through-thickness cracks. This study provides useful tools and guidance for the design and analysis of composite cylinders.
