Plastic is one of the necessities in our daily life nowadays because of its low cost and superior properties. Since the total plastics production grew dramatically over 150 times in the last century, along with the stringent requirement of the analytical standard and safety performance, the devices for detecting glass transitions temperatures (T_g), one of the most important indicators in the thermal analysis of polymers, is highly demanding.

In this research work, the characteristics of the aggregation-induced emission luminogens (AIEgens) are utilized, as their emission intensity is associated with the restriction of intramolecular motion. We proved that the T_g of polymers could be determined by the change in emission intensity of their AIEgens-doped film at different temperatures. Fu...[ Read more ]

Plastic is one of the necessities in our daily life nowadays because of its low cost and superior properties. Since the total plastics production grew dramatically over 150 times in the last century, along with the stringent requirement of the analytical standard and safety performance, the devices for detecting glass transitions temperatures (T_g), one of the most important indicators in the thermal analysis of polymers, is highly demanding.

In this research work, the characteristics of the aggregation-induced emission luminogens (AIEgens) are utilized, as their emission intensity is associated with the restriction of intramolecular motion. We proved that the T_g of polymers could be determined by the change in emission intensity of their AIEgens-doped film at different temperatures. Furthermore, a device prototype and a program for such detection are fabricated. By following easy operating procedures, user can detect the polymeric T_g in 10 minutes. The measured result is accurate, precise and comparable to that obtained by DSC analysis.

To stand out from the fierce competition in the instruments market, our device is differentiated from those existing T_g measuring devices with high sensitivity, low lost, fast detection and small sized. The device will be commercialized in the near future and reached by the target customers through different sales and promotion channels. A detailed commercialization plan was also drafted in this work.
