Pore Size and Volume Effects on the Incorporation of Polymer into Macro- and Mesoporous Zirconium Titanium Oxide Membranes

摘要: Macro- and mesoporous hybrid materials have applications in the fields of drug delivery, catalysis, biosensing, separations. The pore size requirements must be well-understood to maximize performance (e.g., load capacity accessibility) such materials. Hybrid were prepared by coating five distinct macroporous commercial membranes with zirconium titanium oxide through sol−gel chemistry. Calcination these templated produced which had a suite macropore mesopore architectures, volumes, surface areas. These differences physical properties used conduct fundamental study on relationship between volume polymer incorporation. Metal postsynthetically modified poly(ethyleneimine) (PEI) ranging molecular weight from 1300 1 000 000 Da (1.2−11 nm hydrodynamic diameter). incorporation 9 wt % solution at pH 10 was highly dependent and...
