What is it about?

Hydrogel is a kind of flexible soft material, the time distributed-order boundary layer model is proposed to analyze the velocity and temperature distributions during the preparation process. And when the magnetic Reynolds number is large enough, the distribution of the induced magnetic field in the magnetic boundary layer is considered. This paper provides theoretical guidance for improving the performance and quality of hydrogel.

Why is it important?

Hydrogel has a wide range of applications in energy storage devices and flexible electronic equipment because of ductility, viscoelasticity, ionic conductivity, and shape memory property. It is of great significance to research their rheological properties in the molten state and thermal properties by means of the viscoelastic constitutive model, so to understand fundamentally the processability of polymeric material. And the magnetic field is one of the important factors in controlling the cooling rate and achieving the required quality of industrial products. Therefore it is necessary to consider the magnetic diffusion in the boundary layer.

Perspectives

I hope this article can bring some thoughts to those who study polymer solutions and magnetic boundary layer.
