Formation of Strong Hydrogel–Porous Solid Interface via Double Network Principle
نویسندگان
چکیده
A method for binding a tough double-network (DN) hydrogel and a porous solid via the double network principle is proposed. The effects of the pore size of the solids and the structure of the DN gel in the pores on the bonding strength are investigated by a peeling test. Porous solids with pore sizes of the order of several micrometers afford strong gel–substrate interfaces. Under optimized conditions, a bonding strength as high as ~1000 N/m was reached. The results obtained are compared with the strength of the bulk DN gel, and discussed in terms of double network principle at the bonding interface.

A strong solid/liquid interfacial interaction is found between porous alumina and graphene oxide (GO) aqueous dispersion, which promotes a fast enrichment of GO on the alumina surface and results in the formation of a GO hydrogel.
متن کاملReflection and Transmission of Longitudinal Wave at Micropolar Viscoelastic Solid/Fluid Saturated Incompressible Porous Solid Interface
In this paper, the reflection and refraction of longitudinal wave from a plane surface separating a micropolar viscoelastic solid half space and a fluid saturated incompressible half space is studied. A longitudinal wave (P-wave) impinges obliquely at the interface. Amplitude ratios for various reflected and transmitted waves have been obtained. Then these amplitude ratios have been computed nu...
متن کاملVariational Principle and Plane Wave Propagation in Thermoelastic Medium with Double Porosity Under Lord-Shulman Theory
The present study is concerned with the variational principle and plane wave propagation in double porous thermoelastic infinite medium. Lord-Shulman theory [2] of thermoelasticity with one relaxation time has been used to investigate the problem. It is found that for two dimensional model, there exists four coupled longitudinal waves namely longitudinal wave (P), longitudinal thermal wave (T),...
