Dual Cross-Linked Self-Healing and Recyclable Epoxidized Natural Rubber Based on Multiple Reversible Effects

ACS Sustainable Chemistry and Engineering, 2019
Generally, self-healing research based on commercial rubber is of great significance in sustainable development by extending the lifetime of materials. However, it is still a great challenge so far to prepare recyclable rubber that combine excellent self-

Rubber–Rubber Adhesion with Connector Molecules

The Journal of Physical Chemistry, 1992
We consider two rubber blocks A and B in close contact, with some extra A chains (connectors) bound to the surface of the B block and entering freely in the A block. The connectors are assumed not to break, but to slip out by a viscous process when the two blocks are separated.

A New Constitutive Relation for Rubber

, 1996
A simple, two-constant, constitutive relation, applicable over the entire range of strains, is proposed for rubber networks. Behavior in simple extension is derived as an example.

Enhancing the EMI shielding of natural rubber-based supercritical CO2 foams by exploiting their porous morphology and CNT segregated networks.

Nanoscale, 2019
Natural rubber/carbon nanotubes composite foams (F-NR/CNTs) with high electrical conductivity and excellent electromagnetic interference (EMI) performance were developed through a multi-step process including: (a) CNTs assembled on natural rubber latex ...

Rubber and rubber elasticity: A review

Journal of Polymer Science: Polymer Symposia, 1974
AbstractThe physical basis of rubber elasticity is reviewed, particular attention being given to the dependence of elastic stresses upon the imposed strains and upon the molecular constitution of the rubber. Applications of this fundamental understanding to a variety of other phenomena, including thixotropic effects shown by rubbers containing ...

Enhancing the Performance of Rubber with Nano ZnO as Activators.

ACS Applied Materials and Interfaces, 2020
The vulcanization of rubber is a chemical process to improve the mechanical properties by cross-linking unsaturated polymer chains. Zinc oxide (ZnO) acts as an activator, boosting the rubbers' sulfur vulcanization. Maintaining the level of ZnO content in

Strength and deformation behaviour of sand-rubber mixture

, 2020
Loose specimens with a void ratio of 0.86, corresponding to a relative density of 30% for the pure sand, and normal stresses of 50, 100 and 150 kPa were used in this work to study strength and deformation behaviour of sand rubber mixtures. Three types of
