Doped Poly(3-hexylthiophene) Coatings onto Chitosan: A Novel Approach for Developing a Bio-Based Flexible Electronic
Bonardd, Sebastián [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Morales, Natalia; Gence, Loik; Saldias, César; Angel, Felipe A.; Kortaberria, Galder; Leiva, Angel (American Chemical Society, 2020-03)Conductive and flexible bio-based materials consisting of chitosan films coated with conductive poly(3-hexylthiophene) (P3HT) were prepared. Thermal, optical, mechanical, morphological, wettability, and conductive properties ... -
Exploring the Effect of the Irradiation Time on Photosensitized Dendrimer-Based Nanoaggregates for Potential Applications in Light-Driven Water Photoreduction
Bonardd, Sebastián [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada]; Martínez, Natalia P.; Inostroza-Rivera, Ricardo; Durán, Boris; Molero, Leonard; Ramírez, Oscar; Isaacs, Mauricio; Díaz Díaz, David; Leiva, Angel; Saldias, César (MDPI, 2019)Fourth generation polyamidoamine dendrimer (PAMAM, G4) modified with fluorescein units (F) at the periphery and Pt nanoparticles stabilized by L-ascorbate were prepared. These dendrimers modified with hydrophobic fluorescein ... -
Increasing the temperature range of dipolar glass polymers through copolymerization: A first approach to dipolar glass copolymers
Bonardd, Sebastián [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Alegria, Angel; Saldias, César; Leiva, Angel; Kortaberria, Galder (Elsevier BV, 2020-08)This work introduces, for the first time, the dipolar glass copolymer concept as a new strategy to develop polymer dielectrics. Methacrylic monomers containing sulfone and nitrile groups were copolymerized with ... -
Molecular Weight Enables Fine-Tuning the Thermal and Dielectric Properties of Polymethacrylates Bearing Sulfonyl and Nitrile Groups as Dipolar Entities
Saldias, Cesar; Leiva, Angel; Diaz, David; Kortaberria, Galder; Bonardd, Sebastian [Univ Mayor, Ctr Nanotecnol Aplicada, Fac Ciencias, Chile] (MDPI, 2021-02-22)In this work, polymethacrylates containing sulfonyl and nitrile functional groups were successfully prepared by conventional radical polymerization and reversible addition-fragmentation chain-transfer polymerization (RAFT). ...
