Superabsorbent Resin

A poly (sodium acrylate)-polyvinyl alcohol superabsorbent resin is synthesized from acrylic acid (AA) and polyvinyl alcohol. A new method is established to measure the adhesion properties. Then the influence of different experimental conditions on the adhesion properties of the resin is discussed. The results indicate that the adhesion properties of super absorbent resin have some variation with the water absorption increased, the initial pressure and the separation rate. It can be explained by the theory of polymer structure, mechanical interlock and stress relaxation.

Creep And Stress Relaxation

The piezoresistivity and the micro fabrication capability have made the polymer derived ceramics (PDCs) an excellent candidate material for high temperature sensors. In this study, it was found that PDCs also exhibit creep and stress relaxation properties. Its electric resistance may change with time under certain loading conditions. In addition, the creep/stress relaxation rate is sensitive to temperature. It is demonstrated that even PDC materials have been processed at high temperatures and formed ceramic structure, they retain certain polymeric characteristics. Due to the piezoresistivity properties of PDC and its resilience to harsh environment, in particular, the predicted resistance to radiation field, the PDC based sensors are ideal for use as sensing media that can be deployed to important to safety (ITS) structures in nuclear systems, such as cooling water system and coolant pumps in light water reactors (LWRs).
