6 FAQs about [Storage modulus and cross-linking]

Does cross linking increase the storage modulus?

Cross linking increases the interconnection between different long back bone chains, leading to an increase in the elastic energy (stress applied and strain) or storage modulus of the polymer. Cross linking brings about a decrease in chain mobility.

Do crosslinkers with different molecular weights give higher modulus?

Chowdhury et al. . cross-linked epoxy resins using crosslinkers with different molecular weights and found that lower molecular weight crosslinker would impart higher modulus to the material. However, the situation changed when cross-linking bonds of different lengths were mixed.

What drives the modulus of an uncrosslinked material?

In an uncrosslinked material, especially elastomers, the modulus is driven by the difficulty of chains to flow past one another due to entanglements [think noodles]. Crosslinks form a more rigid, non-flowing bulk compared to entanglements.

What is the storage modulus?

In dynamic tests, the storage modulus is a measure of the energy recovered when a certain strain is oscillated in a sample. The tests involve measuring the energy lost (heat, loss modulus E'') and the energy recovered (elastic recovery, storage modulus E'). A high storage modulus signifies that more energy will be recovered.

What is the storage modulus of cross-linked gels?

The storage modulus of cross-linked gels were determined via a DHR-1 rheometer (TA Instrument, USA), equipped with a parallel plate geometry (40 mm diameter and 1 mm gap) at 25 °C.

Does crosslinking density affect thermo-mechanical properties of plant oil-based epoxy resins?

Previous studies suggested that the crosslinking density had a considerable influence on the mechanical and thermal properties of plant oil-based epoxy resins. However, so far, the relationship between the crosslinking density and the thermo-mechanical properties of plant oil-based epoxy resins is not clear.
