Controlling the sensitivity of optical oxygen sensors
If a plasticiser is used to improve the oxygen permeability in an oxygen sensor polymer film, the effect is most dramatic when both polymer and plasticizer are highly compatible. Previous article Next article Keywords Stern–Volmer constant Lumophore Polymer encapsulating media 1. Introduction
Investigation of the Compatibility of a Novel Copolymer Based on
Abstract Plasticizers were added to the polymeric networks to improve the performance of the composite solid propellants. Energetic plasticizers were used to increase the energy content, in addition to improving the glass transition temperature and mechanical properties. The compatibility between polymer and plasticizer is an important criterion for obtaining the best thermomechanical

Bio-Based Plasticizers Stretch Production Capability
Compatibility assures the plasticizer stays put to provide the desired softness and flexibility. If the plasticizer has poor compatibility it can lead to blooming which can make the plasticizer fugitive, and lead to the polymer becoming brittle, stiff, hard, or weak.
- Why do polymers need plasticizers?
- The plasticizers reduce the glass transition temperature, and the viscosity of the polymer also enhances the flexibility and processability of polymer materials. The main problem of these additives is that, over time, they migrate from the polymeric matrix and exude to the surface of polymeric matrix.
- What is a reactive plasticizer?
- Learn more. This review is about the reactive plasticizer. Plasticizers are small molecules with low molecular weight. These compounds typically have an esteric structure. The plasticizers reduce the glass transition temperature, and the viscosity of the polymer also enhances the flexibility and processability of polymer materials.
- Do plasticizers covalently bond to polymeric chains?
- An approach that has recently been of great interest to researchers is the use of reactive plasticizers. In this approach, plasticizers covalently bond to the polymeric chains and prevent migration. Chapter 22.

- What are the problems with polymer additives?
- The main problem of these additives is that, over time, they migrate from the polymeric matrix and exude to the surface of polymeric matrix. As a result, the physical and mechanical properties of the polymer are affected.
- What happens if a ionophore has an excess plasticizer?
- When an excess plasticizer is present, the ionophore loses its ability to selectively sense the ion of interest. Some commonly used plasticizers in the fabrication of ISE are- di-octyl sebacate (DOS), tributyl phosphate (TBP), dibutyl phthalate (DBP), 2-nitrophenyl octyl ether (NPOE).
- Which plasticizer is used in the fabrication of Ise?
- Some commonly used plasticizers in the fabrication of ISE are- di-octyl sebacate (DOS), tributyl phosphate (TBP), dibutyl phthalate (DBP), 2-nitrophenyl octyl ether (NPOE). The amount of plasticizer in the membrane influences the response time of the ISE .
