Photoactive Boron–Nitrogen–Carbon Hybrids: From Azo-borazines to Polymeric Materials

Electrokinetic devices from polymeric materials

A Brief Introduction to Polymeric Materials

A structural engineer who wishes to use adhesives must understand at least the rudiments of polymer chemistry, in much the same way that a structural engineer working with metal alloys must understand at least the rudiments of metallurgy. A brief introduction to polymer material science is given in the following subsections. The underlying objective of this discussion is to simply define some o...

Polymeric triple-shape materials.

Shape-memory polymers represent a promising class of materials that can move from one shape to another in response to a stimulus such as heat. Thus far, these systems are dual-shape materials. Here, we report a triple-shape polymer able to change from a first shape (A) to a second shape (B) and from there to a third shape (C). Shapes B and C are recalled by subsequent temperature increases. Whe...

Polymeric Dielectric Materials

The definition for dielectric constant relates to the permittivity of the material (symbol use here ε). The permittivity expresses the ability of a material to polarise in response to an applied field. It is the ratio of the permittivity of the dielectric to the permittivity of a vacuum. Physically it means the greater the polarisation developed by a material in an applied field of given streng...
