Solvay Advanced Polymer of Belgium supplied the polysulfone. Sigma-Aldrich provided the following materials: tetraethylorthosilicate, 3-amino-propyltriethoxysilane, 3-mercaptopropyl trimethoxysi, ethylene sulfide, n-hexane, ammonium nitrate, ammonium hydroxide, cadmium nitrate, and lead nitrate. Ammonium, chlorine, and sodium hydroxide were obtained by Fisher Scientific. Polyethylene glycol with various molecular weights (200, 300, 600, and 1000 g/mol) was purchased at Merck and used for the MWCO measurements. N, N-dimethylformamide, and toluene were received from BDH. Every chemical was utilized in its exact, provided form. Deionized water was utilized for the entire experiment.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
