An Investigation on the Role of Metal-Organic Framework (MOF) on the Network Structure and Physical/Mechanical Properties of EPDM Rubber
, M.Sc. Thesis Sharif University of Technology ; Molvai, Hossein (Supervisor)
Abstract
Ethylene-propylene-diene monomer rubber (EPDM) is one of the elastomers that shows non-polar behavior, high elasticity at low temperatures, excellent thermal and ozone resistance, and high electrical resistance. In this respect, it is used in various applications such as sealing materials, conveyor belts, waterproof materials, cables, etc. One of the most important applications of this rubber is its use as a sealing material. In this case, the resilience behavior plays an important role in the sealing behavior of the EPDM rubber. Especially in cases such as the car's hydraulic braking system where high service temperatures and dynamic stresses are applied, resilience behavior will be more...
The Role of Surface Functionalization of Nanodiamond on the Vulcanization Kinetics and Network Structure of SBR
, M.Sc. Thesis Sharif University of Technology ; Shojaie, Akbar (Supervisor)
Abstract
Elastomers are flexible polymers with various uses in different industries. But this materials dont havevalid usages without correct fillers. Today Nano technology has a main role in the industry. one of the important reasons is rubber quality improvement with adding just a little amount of this clays, opposite to Carbon Black. To achieve a high quality polymer composite, it is necessary to learn about physical and mechanical properties of nano clays and the interaction between Nano clays and matrix. Because of the effect of nano clays on vulcanization, this issue is noticeable . Nano diamond is a nanoclay used to improve rubber quality. But this method is new because of the complicated...
