Takimoto, Ken published the artcileExploring stabilizer formulations for light-induced yellowing of polystyrene by high-throughput experimentation and machine learning, Safety of Bis(2,2,6,6-tetramethylpiperidin-4-yl) decanedioate, the main research area is photo induced yellowing inhibition polystyrene stabilizer formulation machine learning.
In this study, a high-throughput exptl. protocol was established for yellowing inhibition of transparent plastics on the basis of solution film casting on microplates and UV/visible (UV/Vis) spectroscopic evaluation using a microplate reader. A combination of the protocol and a genetic algorithm realized a large-scale exploration of stabilizer formulations that consist of com. available hindered amine stabilizers and UV absorbers, etc. The found formulations were highly effective in inhibiting the photo-induced yellowing of polystyrene, compared to the most efficient single stabilizer at the fixed concentration The obtained data, which corresponded to seven years of aging (when sequentially acquired), were analyzed and validated based on decision tree classification, force-directed network visualization, and so on. A formulation design guideline was successfully derived that it is essential to combine as many stabilizers that are complementary and synergistic with each other as possible.
