Microscale Interfacial Polymerization on a Chip. [PDF]
Angew Chem Int Ed Engl, 2021 AbstractForming hydrogels with precise geometries is challenging and mostly done using photopolymerization, which involves toxic chemicals, rinsing steps, solvents, and bulky optical equipment. Here, we introduce a new method for in situ formation of hydrogels with a well‐defined geometry in a sealed microfluidic chip by interfacial polymerization. The

Microencapsulation of Photochromic Solution with Polyurea by Interfacial Polymerization. [PDF]
Polymers (Basel), 2021 Photochromic materials are interesting materials because of their color-changing property under UV light and visible light irradiation. However, they are vulnerable to many factors, such as pH oxygen, ion, solvent, etc. because of the unsaturated bonds existing on the photochromic molecular. Microencapsulation of the photochromic materials can separate

When self-assembly meets interfacial polymerization. [PDF]
Sci Adv, 2023 Interfacial polymerization (IP) and self-assembly are two thermodynamically different processes involving an interface in their systems. When the two systems are incorporated, the interface will exhibit extraordinary characteristics and generate structural and morphological transformation.

The synthesis and some properties of nylon 4,T [PDF]
, 1985 The synthesis of nylon 4,T from tetramethylenediamine and a terephthalic acid derivative was studied in a two step-process: prepolymerization, followed by postcondensation in the solid state (4 h, 290°C).

A Multi-Scale Approach to Microencapsulation by Interfacial Polymerization. [PDF]
Polymers (Basel), 2021 This work applies a multi-scale approach to the microencapsulation by interfacial polymerization. Such microencapsulation is used to produce fertilizers, pesticides and drugs. In this study, variations at three different scales (molecular, microscopic and macroscopic) of product design (i.e., product variables, process variables and properties) are ...

Polyamide-based membranes with structural homogeneity for ultrafast molecular sieving
Nature Communications, 2022 Thin-film composite membranes formed by conventional interfacial polymerization generally suffer from depth heterogeneity of the polyamide layer. Here, authors investigate salt-mediated polymerization approaches to achieve membranes with tuneable ...

Interfacial Properties of Polymeric Liquids [PDF]
Physical Review Letters, 2000 We show that the variations of the surface tension of polymeric solutions gamma with the molecular weight of the sample M(n), the temperature T, and the volume fraction of monomers straight phi(b) are explained by the self-organization of the long flexible chains that are present in the immediate vicinity of the interface.
