Interfacial Polymerization of Silica Nanoparticles to Create Modifiable, Ultra-Thin, Ultrafiltration Membranes
Bibliographic record
Abstract
Interfacial polymerization is an industrially scalable technique, most notably used in the fabrication of reverse osmosis membranes, with the ability to create highly crosslinked thin films. This work successfully expands the interfacial polymerization chemistry library by utilizing 1D nanomaterials to create highly crosslinked, modifiable, defect-free nanoparticle membranes. Silica nanoparticles were used as a proof-of-concept due to their straightforward synthesis and chemical modification, exemplifying the feasibility of integrating nanoparticles into this established technique. Careful selection of the crosslinking agent in the interfacial polymerization scheme allowed for film thicknesses between 100 nm and 1.6 μm to be achieved. The nanoparticle layer exhibited poor mechanical stability under pressure and required a low pore size, high strength support membrane for stable operation. Chemical modification of the nanoparticle film with a hydrophobic polymer altered the water contact angle from 26° to 95°, showing ease of control over surface chemistry. This approach could be readily expanded to incorporate other types of nanoparticles and be applied to a wide range of applications beyond ultrafiltration.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
