The Carbon Nanotubes Effect into Single-lap Joint Failure Modes and Load Capacity: a Macromechanical Analysis [PDF]

Materials Research, 2018
This study investigates the influence of the adhesive (epoxy resin) thickness and the dispersions of non-functionalized carbon based nanostructures (carbon nanotubes - CNT) on mechanical properties of single-lap bonded joints. To achieve this goal, three

BRANCHED POLYMERS ON BRANCHED POLYMERS [PDF]

Modern Physics Letters A, 1996
We study an ensemble of branched polymers which are embedded on other branched polymers. This is a toy model which allows us to study explicitly and in detail the reaction of a statistical system to its underlying geometrical structure, a problem of interest in the study of the interaction of matter and quantized gravity. We find a phase transition at

Crystal structure and Hirshfeld surface analysis of one-dimensional copper(II) coordination polymer incorporating succinate and tetramethylethylenediamine ligands

Acta Crystallographica Section E: Crystallographic Communications, 2020
The reaction of copper nitrate with succinic acid (succH) and N,N,N′,N′-tetramethylethylenediamine (TMEDA) in basic solution produces the complex catena-poly[[[(N,N,N′,N′-tetramethylethylenediamine-κ2N,N′)copper(II)]-μ-succinato-κ2O1:O4] tetrahydrate], {[

Nanoscale friction and wear of a polymer coated with graphene

Beilstein Journal of Nanotechnology, 2022
Friction and wear of polymers at the nanoscale is a challenging problem due to the complex viscoelastic properties and structure. Using molecular dynamics simulations, we investigate how a graphene sheet on top of the semicrystalline polymer polyvinyl ...

Unprecedented Scissor Effect of Macromolecular Cross-linkers on the Glass Transition Temperature of Poly(N-vinylimidazole), Crystallinity Suppression of Poly(tetrahydrofuran) and Molecular Mobility by Solid State NMR in Poly(N-vinylimidazole)-l-poly(tetrahydrofuran) Conetworks [PDF]

, 2013
Unexpected correlations have been found between structural parameters and glass transition temperatures (Tg) of poly(N-vinylimidazole) (PVIm) and crystallinity of poly(tetrahydrofuran) (PTHF) in a series of novel, unique PVIm-l-PTHF amphiphilic ...

Understanding the role of MAM molecular weight in the production of PMMA/MAM nanocellular polymers [PDF]

, 2018
Nanostructured polymer blends with CO2-philic domains can be used to produce nanocellular materials with controlled nucleation. It is well known that this nanostructuration can be induced by the addition of a block copolymer poly(methyl methacrylate ...

A statistical theory of polymer network degradation [PDF]

, 2014
A statistical theory was proposed for the degradation (random scission of chains) of a network having f-functional nodes in the case where all chains contain equireactive groups and a chain scission event does not create new groups or suppress more than ...
