Phenolic Resin Dual-Use Stamps for Capillary Stamping and Decal Transfer Printing [PDF]

open access: yesACS Appl. Mater. Interfaces 2021, 13 (41), 49567-49579, 2021
We report an optimized two-step thermopolymerization process carried out in contact with micropatterned molds that yields porous phenolic resin dual-use stamps with topographically micropatterned contact surfaces. With these stamps, two different parallel additive substrate manufacturing methods can be executed: capillary stamping and decal transfer ...

Tailored pore gradient in phenolic membranes for adjustable permselectivity by leveraging different poloxamers [PDF]

open access: yesSep. Purif. Technol. 242 (2020) 116818, 2020
Cost-affordable phenolic membranes having gradient nanostructures can be facilely synthesized from resol oligomers in the presence of ZnCl2 and poloxamers. The gradient nanostructures are formed by stacking phenolic nanoparticles with gradually enlarged diameters as the distance from the upper surface increases.
