Crystallization and Morphology of Triple Crystalline Polyethylene-b-poly(ethylene oxide)-b-poly(ε-caprolactone) PE-b-PEO-b-PCL Triblock Terpolymers
Matxinandiarena Almandoz, Eider; Mugica Iztueta, Miren Agurtzane; Zubitur Soroa, María Manuela; Ladelta, Viko; Zapsas, George; Cavallo, Dario; Hadjichristidis, Nikos; Müller Sánchez, Alejandro Jesús (MDPI, 2021-09-16)The morphology and crystallization behavior of two triblock terpolymers of polymethylene, equivalent to polyethylene (PE), poly (ethylene oxide) (PEO), and poly (ε-caprolactone) (PCL) are studied: PE227.1-b-PEO4615.1-b-PCL3210.4 ... -
Direct Identification of Three Crystalline Phases in PEO-b-PCL-b-PLLA Triblock Terpolymer by In Situ Hot-Stage Atomic Force Microscopy
Palacios, Jordana K; Zhang, Heng; Zhang, Bin; Hadjichristidis, Nikos; Müller Sánchez, Alejandro Jesús (Elsevier, 2020-08-04)In this work, we provide a detailed description of the tri-lamellar nanoscale morphology of a triple crystalline PEO-b-PCL-b-PLLA triblock terpolymer obtained by Hot-Stage Atomic Force microscopy (AFM) imaging and Wide ... -
Generating Triple Crystalline Superstructures in Melt Miscible PEO-b-PCL-b-PLLA Triblock Terpolymers by Controlling Thermal History and Sequential Crystallization
Palacios Gutiérrez, Jordana Karin ; Liu, Guoming; Wang, Dujin; Hadjichristidis, Nikos; Müller Sánchez, Alejandro Jesús (WILEY-VCH, 2019-09-10)The morphology, crystallization behavior and properties of multi-crystalline polymer systems based on triple crystalline biodegradable PEO-b-PCL-b-PLLA triblock terpolymers are reviewed. The triblock terpolymers, with ... -
Influence of chain topology on gel formation and direct ink printing of model linear and star block copolymers with poly(ethylene oxide) and poly(ε-caprolactone) semi-crystalline blocks
Centeno, Edward; Peñas Núñez, Mario Iván; Zhang, Pengfei; Ladelta, Viko; Mercado Rico, Jorge; Matxinandiarena Almandoz, Eider; Zubitur Soroa, María Manuela; Mugica Iztueta, Miren Agurtzane; Hadjichristidis, Nikos; Müller Sánchez, Alejandro Jesús ; Hernández, Rebeca (Elsevier, 2023-12-11)In this work, a set of well-defined linear triblock copolymers and star block copolymers (3 and 4-arms) with semi crystalline blocks consisting of poly(ethylene oxide) (PEO) and poly(epsilon-caprolactone) (PCL), synthesized ... -
Microscopic Evidence for the Topological Transition in Model Vitrimers
Arbe Méndez, María Aranzazu; Alegría Loinaz, Angel María ; Colmenero de León, Juan ; Bhaumik, Saibal; Ntetsikas, Konstantinos; Hadjichristidis, Nikos (ACS, 2023-11)In addition to the glass transition, vitrimers undergo a topological transition from viscoelastic liquid to viscoelastic solid behavior when the network rearrangements facilitated by dynamic bond exchange reactions freeze. ... -
