The mechanical and electrical properties of direct-spun carbon nanotube mat-epoxy composites [PDF]
Carbon 2019, 2019 Composites of direct-spun carbon nanotube (CNT) mats and epoxy are manufactured and tested in order to determine their mechanical and electrical properties. The mats are spun directly from a floating catalyst, chemical vapour deposition reactor.

Electrical conductivity of multi-walled carbon nanotubes-SU8 epoxy composites [PDF]
Appl. Phys. Lett. vol.102, 223114 (2013), 2013 We have characterized the electrical conductivity of the composite which consists of multi-walled carbon nanotubes dispersed in SU8 epoxy resin. Depending on the processing conditions of the epoxy (ranging from non-polymerized to cross-linked) we obtained tunneling and percolating-like regimes of the electrical conductivity of the composites.

Feature-based prediction of properties of cross-linked epoxy polymers by molecular dynamics and machine learning techniques [PDF]
arXiv, 2023 Epoxy polymers are used in wide range of applications. The properties and performance of epoxy polymers depend upon various factors like the type of constituents and their proportions used and other process parameters. The conventional way of developing epoxy polymers is usually labor-intensive and may not be fully efficient, which has resulted in ...

A study of radiation tolerance in optical cements [PDF]
, 2020 We study the effect ionizing radiation has on light transmission in the wavelength range 190--1100~nm for a number of optically clear epoxies. We find that the transmittance of traditional, commercially available, optical epoxies show significant degradation for exposures of $1\times10^{12}$~MIPs/cm$^2$.

Piezoelectric polyvinylidene fluoride-based epoxy composites produced by combined uniaxial compression and poling [PDF]
Appl. Phys. Lett. 115, 192902 (2019), 2019 We present a simple, efficient method, which combines uniaxial compression and subsequent poling, to produce piezoelectric polyvinylidene fluoride-based epoxy composites. The values of the piezoelectric factors obtained are slightly higher than those of neat piezoelectric polyvinylidene fluoride.

Recyclable flame-retardant epoxy composites based on disulfide bonds. Flammability and recyclability [PDF]
, 2021 A series of recyclable epoxy resin (REP) composites are successfully prepared in this study, aiming to improve flame retardancy while keep good recyclability and mechanical properties. The commercial 9,10-Dihydro-9-oxa-10-phosphaphenanthrene 10-Oxide (DOPO) with high reactive P-H bond is used as highly-efficient flame retardant in this work.

Thermal Conductivities and Mechanical Properties of Epoxy Resin as a Function of the Degree of Cross-linking [PDF]
arXiv, 2021 Epoxy resins are widely used polymer matrices for numerous applications. Despite substantial advances, the molecular-level knowledge-base required to exploit these materials to their full potential remains limited. A deeper comprehension of structure/property relationships in epoxy resins at the molecular level is critical to progressing these efforts.

Divanillin-based aromatic amines: synthesis and application as curing agents for bio-based epoxy thermosets [PDF]
Frontiers in Chemistry, Frontiers, 2019, 7, 2019 New bio-based diamines were successfully synthesized from vanillin and fully characterized. These amines, methylated divanillylamine (MDVA) and 3,4-dimethoxydianiline (DMAN), were then used as curing agent with epoxy monomers. Epoxy thermosets obtained from these new bio-based amines exhibited promising thermomechanical properties in terms of glass ...
