Application

Poly(vinylsulfonicacid, sodium salt) (PVSA) can be used:

  • In the preparation of superabsorbent semi-IPN (interpenetrating polymer network) hydrogel.
  • As a solid electrolyte for proton conduction in the fabrication of an all-solid-supercapacitor.
  • As a crystallization controlling agent in the preparation of high-quality crystals of porous coordination polymers(CP). PVSA regulates not only the size and structure of the crystals but also their preference orientation, resulting in CP channel alignment in the bulk powdery state.

Bidirectional ITP in fused-silica capillaries double-coated with Polybrene and poly-(vinylsulfonate) is a robust approach for analysis of low-molecular-mass compounds. EOF towards the cathode is strong (mobility >4.0 x 10(-8) m(2)/Vs) within the entire pH range investigated (2.40-8.08), dependent on ionic

Layer-by-Layer (LbL) Assembly, A "Gentle Yet Flexible" Method Toward Functional Biomaterials

Recently, layer-by-layer (LbL) assembly has emerged as a versatile, gentle and, simple method for immobilization of functional molecules in an easily controllable thin film morphology.1,2 In this short review, we introduce recent advances in functional systems fabricated by using the mild, yet adaptable LbL technique.

Polyelectrolyte Multilayer Films and Membrane Functionalization

We present an article that discusses two applications in particular; first, using these layers as polyelectrolyte membranes to control permeability.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
