  • Publication number: 20240100485
    Abstract: Asymmetric films, methods of making asymmetric films, and uses of asymmetric films. A method may include using at least two different solvents and at least one homopolymer and at least one block copolymer that can undergo self assembly, where the solvents are immiscible and have different surface tension, where, on film formation, all or substantially all of the block copolymer(s) migrate to an exterior surface of the homopolymer. The asymmetric films may include an isoporous region or layer and an asymmetric region or layer, where the asymmetric region does not include 10 percent by weight or more of the multiblock copolymer(s) and/or the isoporous region/layer and the asymmetric pore region/layer are not independently (or separately) formed and/or not laminated together to form the asymmetric film. The films can be used in devices, such as, for example, filtration devices.

  • Patent number: 11724232
    Abstract: A method providing direct access to porous three-dimensionally (3D) continuous polymer network structures and shapes by combining BCP-resol co-assembly with CO2 laser-induced transient heating. The CO2 laser source transiently heats the BCP-directed resol hybrid films to high temperatures at the beam position, inducing locally controlled resol thermopolymerization and BCP decomposition in ambient conditions. This enables shaping of BCP-directed porous resin structures with tunable 3D interconnected pores in a single process. Pore size can be varied from 10 nm to about 600 nm.

  • Publication number: 20230201379
    Abstract: Described is a versatile surface modification approach to, for example, modularly and orthogonally functionalize nanoparticles (NPs) such as, for example, PEGylated nanoparticles, ith various types of different functional ligands (functional groups) on the NP surface. It enables the synthesis of, for example, penta-functional PEGylated nanoparticles integrating a variety of properties into a single NP, e.g., fluorescence detection, specific cell targeting, radioisotope chelating/labeling, ratiometric pH sensing, and drug delivery, while the overall NP size remains, for example, below 10 nm.

  • Publication number: 20230140770
    Abstract: An aqueous synthesis methodology for the preparation of silica nanoparticles (SNPs), core-shell SNPs having, for example, a size of 2 to 15 nm and narrow size-dispersion with size control below 1 nm, i.e. at the level of a single atomic layer. Different types of dyes, including near infrared (NIR) emitters, can be covalently encapsulated within and brightness can be enhanced via addition of extra silica shells. The surface may be functionalized with polyethylene glycol (PEG) groups and, optionally, specific surface ligands. This aqueous synthesis methodology also enables synthesis of 2 to 15 nm sized fluorescent core and core-shell aluminosilicate nanoparticles (ASNPs) which may also be surface functionalized. Encapsulation efficiency and brightness of highly negatively charged NIR fluorophores is enhanced relative to the corresponding SNPs without aluminum.

The generation of blended membranes by mixing two chemically distinct block copolymers in the casting solution demonstrates a pathway to advanced asymmetric block copolymer derived films, which can be used as ultrafiltration membranes, in which different pore surface chemistries and associated functionalities can be integrated into a single membrane via standard membrane fabrication, i.e. without requiring laborious post-fabrication modification steps. The block copolymers may be diblock, triblock and/or multiblock mixes and some block copolymers in the mix may be functionally modified. Triblock copolymers comprising a reactive group (e.g.
