What is the difference between PRP and PTP?

1. Structure and composition

The main difference between the probe PRP and the probe PTP is the structure of the base material and the probe group. The matrix of the probe PRP is polypropylene (PP), while the matrix of the probe PTP is polystyrene (PT). Polypropylene usually has a high molecular weight and good mechanical properties, while polystyrene has a relatively low molecular weight and a relatively loose structure.

The probe group of the probe PRP is usually a carboxylic acid compound, such as carboxylic acid, methyl methacrylate (CPAM), etc., and these groups give the probe PRP good acid-base sensor characteristics. The probe groups of the probe PTP are mostly carboxylic acid ester compounds, such as polymethyl acrylate (PPAM), polyethyl acrylate (PPBA), etc. These groups perform well in the detection of organic molecules.

2. Chemical performance

Probe PRP and probe PTP also have significant differences in chemical properties. The polypropylene matrix of the probe PRP has high thermal stability and can withstand high temperatures, but it may deform under low temperature conditions. The polystyrene matrix of the probe PTP has good low temperature stability, but it may decompose or release harmful substances under high temperature conditions.

The probe group of the probe PRP has good acid-base ligand characteristics, can interact with acid-base substances, and is widely used in the field of acid-base sensors. The probe group of the probe PTP has stronger electrophilicity, can interact with organic molecules, and is often used in the manufacture of organic molecular sensors.

3. Application field

The main application areas of probe PRP and probe PTP are different. The probe PRP is commonly used in acid-base sensors, pH detection devices, etc., and is suitable for detecting acid, alkali, and salt plasma substances. The probe PTP is commonly used in organic molecular sensors, suitable for detecting aromatic compounds, organic pollutants and so on.

4. Performance characteristics

The main advantages of probe PRP are stable structure, reliable performance, and suitable for manufacturing long-life sensors. Probe PRP is less sensitive to organic molecules than probe PTP. The probe PTP has the characteristics of light structure, high sensitivity and good selectivity, and is suitable for rapid detection and trace analysis.

5. Advantages and disadvantages analysis

The advantage of the probe PRP is that it is structurally stable and suitable for manufacturing long-life sensors. The disadvantage is that the probe group has weak acid-base ligand characteristics and limited response to organic molecules. The advantage of the probe PTP is that the probe group is electrophilic and can react strongly with organic molecules. The disadvantage is that the structure is relatively light and is not suitable for manufacturing long-life sensors.

Summary

Probe PRP and probe PTP are two kinds of sensor materials with different uses, and they have significant differences in structure, performance and application. The probe PRP is suitable for acid-base sensors and long-life applications, while the probe PTP is suitable for organic molecular sensors and rapid detection. The choice of sensor material needs to be determined according to the specific application requirements.
