Macromolecular Imprinting by sol-gel silica in the presence of polymer grafted carbon black

摘要

A novel method of producing macromolecular imprinted silica particles (MIP) in the presence of polymer grafted carbon black is presented. For the silica gel matrix, tetraethyl orthosilicate (TEOS) was used as the backbone monomer and 3-aminopropyl triethoxysilane (APS) as a functional monomer. Carbon black was added to the sol-gel process, yielding black silica particles. A total of 16 MIP's were synthetized in parallel with four variables in order to better understand and evaluate the role of key reactants in the synthesis procedure. Agglomeration tests were performed with all 16 MIP's in the presence of their template, alongside their respective controls using only PBS. Each of the MIPs were evaluated using an in house built device capable of simultaneously measuring up to four samples for near infrared transmission.
