Separation of Organic Molecules through Track-Etched Nanopores in PET Membranes
نویسندگان
چکیده
Chemical separations play an important role in most chemical, pharmaceutical, and petrochemical processes. Membrane-based separations are potentially important because they can be less energy intensive and more economical than conventional separation methods [1]. By controlling the pore diameter of track-etched nanoporous polymer membranes, they can be used as nanofilters for the separation of molecules based on their size. Nanopore surfaces have been gold-plated electroless and subsequently modified via chemisorption of a variety of different thio-molecules to control the surface properties, e.g., charge or hydrophobicity [2,3]. 200 250 300 350 400 450 0.0 0.1 0.2 0.3 0.4

Nanopores with controlled profiles in track-etched membranes
The production of the track-etched membranes is well known in membrane science. Latent ion tracks are the result of the passage of swift ions through solid matter, they can be etched selectively in many materials. As a result, conical, cylindrical or other shape channels can be obtained. The increasing interest in polymer track-etched membranes with nano-channels is connected with the developme...
متن کاملLow-voltage electroosmotic pumps fabricated from track-etched polymer membranes.
Track-etched polymer membranes are used to realize low-voltage electroosmotic (EO) pumps. The nanopores in polycarbonate (PC) and polyethylene terephthalate (PET) membranes were fabricated by the track-etching technique, the pore diameter was controlled in the range of 100 to 250 nm by adjusting the etching time. The results show that these EO pumps can provide high flow rates at low applied vo...
متن کاملEvaluation of Vapor Deposition Techniques for Membrane Pore Size Modification
The suitability of three vapor deposition techniques for pore size modification was evaluated using polycarbonate track etched membranes as model supports. A feature scale model was employed to predict the pore geometry after modification and the resulting pure water flux. Physical vapor deposition (PVD) and pulsed plasma-enhanced chemical vapor deposition (PECVD), naturally, form asymmetric na...
متن کاملA Two-Step Etching Method to Fabricate Nanopores in Silicon
A cost effectively method to fabricate nanopores in silicon by only using the conventional wet-etching technique is developed in this research. The main concept of the proposed method is a two-step etching process, including a premier double-sided wet etching and a succeeding track-etching. A special fixture is designed to hold the pre-etched silicon wafer inside it such that the track-etching ...
متن کاملChemical Modification of track-etched dingle conical nanopores inducing inversed inner wall polarity
Nanopores are currently considered as promising candidates for a variety of applications, including separation techniques and biological sensing [1,2]. The pore surface properties are crucial for all these applications, since they influence the transport properties (e.g. hydrophobicity, selectivity) and chemical groups on the inner pore walls may serve as binding sites for analytes [3]. Therefo...
