1. Improved natural rubber composites reinforced with a complex filler network of biobased nanoparticles and ionomer

Author:

Materials chemistry and physics 2018 v.203 no. pp. 156-165
ISSN:
0254-0584
Subject:
biopolymers; carboxylation; cohesion; hydrophilicity; mechanical stress; modulus of elasticity; nanoparticles; rubber; soot; tensile strength
Abstract:
... Biobased rubber composites are renewable and sustainable. Significant improvement in modulus of rubber composite reinforced with hydrophilic filler was achieved with the inclusion of ionomers. Soy particles aided with ionomer, carboxylated styrene-butadiene (CSB), formed a strong complex filler network in rubber. The effect of CSB caused Young's modulus and the tensile stress at 100-300% elongatio ...

Subject:
latex; mechanical stress; methodology; models; nanoparticles; particle size; rolling; rubber; soot; soy protein; tensile strength
Abstract:
... Mechanical properties of natural rubber reinforced with soy protein nanoparticles are useful for various rubber applications. However, the properties is further improved by improving interactions between soy protein and rubber. A novel method is used to modify particle surface of natural rubber latex by grafting with diallylamine. The improved polymer-filler interactions caused tensile stress at 3 ...

Journal of polymers and the environment 2015 v.23 no.4 pp. 541-550
ISSN:
1566-2543
Subject:
crosslinking; hydrolysis; particle size; rubber; soot; tensile strength; wheat flour; wheat gluten
Abstract:
... The toughness of natural rubber can be improved by using fillers for various rubber applications. Dry wheat gluten is a protein from wheat flour and is sufficiently rigid for rubber reinforcement. The wheat gluten was hydrolyzed to reduce its particle size and microfluidized to reduce and homogenize the particle size and size distribution. The processed wheat gluten aggregates with a size of ~500  ...

Subject:
composite materials; crosslinking; hydrolysis; particle size; rubber; soy protein; tensile strength; transmission electron microscopy
Abstract:
... For natural rubber applications, the reinforcing fillers are used to improve the mechanical properties of the rubber. Soy protein particles have been shown to reinforce natural rubber. The hydrolysis conditions of soy protein are studied to understand its effect on the particle size and size distribution, and their subsequent effect on the mechanical properties of natural rubber. The reinforced an ...

Industrial crops and products 2014 v.55 pp. 25-32
ISSN:
0926-6690
Subject:
modulus of elasticity; protein aggregates; rubber; soy protein concentrate; storage modulus; tensile strength; viscosity
Abstract:
... Improved mechanical properties of natural rubber are required for various rubber applications. Aggregates of protein and fiber that constitute soy protein concentrate were shear-reduced and used to enhance the tensile modulus of the natural rubber. The aqueous dispersion of the shear-reduced aggregates has a higher viscosity and shear storage modulus. The reduced aggregates in the natural rubber i ...

Abstract:
... The porous carbons derived from cellulose are renewable and environmentally friendly. Coconut shell and wood derived porous carbons were characterized with elemental analysis, ash content, X-ray diffraction, infrared absorbance, particle size, surface area, and pore volume. The results were compared with carbon black. Uniaxial deformation of natural rubber (NR) composites indicate the composites r ...
