Non-Einstein Viscosity Phenomenon of Acrylonitrile–Butadiene–Styrene Composites Containing Lignin–Polycaprolactone Particulates Highly Dispersed by High-Shear Stress

open access: yes, 2019
Lignin powder was modified via ring-opening polymerization of caprolactone to form a lignin–polycaprolactone (LPCL) particulate. The LPCL particulates were mixed with an acrylonitrile–butadiene–styrene (ABS) matrix at an extremely high rotational speed ...

Scalable Layer‐by‐Layer Electrospray‐Assisted Interfacial Polymerization: Enabling Large‐Area Polyamide Membrane Fabrication

open access: yesAdvanced Materials Technologies, EarlyView.
We report a multi‐jet, layer‐by‐layer electrospray‐assisted interfacial polymerization (LBL‐EAIP) approach for the scalable fabrication of polyamide reverse osmosis (RO) membranes. The method enables precise control of polymerization, uniform polyamide coverage, and tunable polyamide film thickness, while delivering consistently high filtration ...
