High solids content, soap-free, film-forming latexes stabilized by laponite clay platelets.
Elodie Bourgeat-Lami,Thiago R. Guimarães,Ana Maria Cenacchi Pereira,Ana Maria Cenacchi Pereira,Gizelda M. Alves,José Carlos Moreira,Jean-Luc Putaux,Amilton M. Santos +7 more
TL;DR: The overall polymerization kinetics showed a pronounced effect of clay on nucleation and stabilization of the latex particles and the resulting nanostructured films displayed enhanced mechanical properties.
Synthesis of amphiphilic pullulan-graft-poly(ε-caprolactone) via click chemistry.
Layde T. Carvalho,Rodolfo M. Moraes,Gizelda M. Alves,Talita M. Lacerda,Julio C. Santos,Amilton M. Santos,Simone F. Medeiros +6 more
TL;DR: This work describes the synthesis and characterization of a novel amphiphilic pullulan-g-poly(ε-caprolactone) (Pull- g-PCL) graft copolymer, capable of being linked together via alkyne-azide cycloaddition reaction catalyzed by copper.
