Even-odd Effect in Aliphatic Polycarbonates with Different Chain Lengths: from Poly (hexamethylene carbonate) to Poly (dodecamethylene carbonate)
(ACS, 2020-12-17)
We have characterized a series of aliphatic polycarbonates synthesized by organocatalysis containing a variable number of methylene groups (nCH2) in their repeat units ranging from nCH2 = 6 to 12. The melting and crystallization ...
Organocatalyzed Polymerization of PET-mb-poly(oxyhexane) Copolymers and Their Self-Assembly into Double Crystalline Superstructures
(ACS Publications, 2019-08-30)
Double crystalline multi-block copolymers exhibit two well-defined melting temperatures associated with the two phases formed by their constituent blocks. The crystalline superstructure formed in these copolymers is complex ...
Using Successive Self-nucleation and Annealing (SSA) to detect the solid-solid transitions in poly (hexamethylene carbonate) and poly (octamethylene carbonate)
(ACS, 2021-10-26)
Solid-solid transitions in poly (hexamethylene carbonate) (PC6) and poly (octamethylene carbonate) (PC8), denoted δ to α transition, have been investigated, using self-nucleation and Successive Self-nucleation and Annealing ...
3D Printed Bioplastics with Shape-Memory Behavior Based on Native Bovine Serum Albumin
(ACS, 2022-04-19)
Bio-based plastics that can supplant petroleum-derived materials are necessary to meet the future demands of sustainability in the life cycle of plastic materials. While there are significant efforts to develop protein-based ...
Sustainable Materials and Chemical Processes for Additive Manufacturing
(ACS, 2020-08-03)
Additive manufacturing (AM) is energizing the fields of chemistry and materials science to develop new inks for new applications within fields such as aerospace, robotics, and healthcare. AM enables the fabrication of ...
Enantioselective Ring-Opening Polymerization of rac-Lactide Dictated by Densely Substituted Aminoacids
(ACS, 2017-03-08)
Organocatalysis is becoming an important tool in
polymer science because of its versatility and specificity. To date
a limited number of organic catalysts have demonstrated the
ability to promote stereocontrolled ...
From Plastic Waste to New Materials for Energy Storage
(Royal Society of Chemistry, 2022-07-06)
The use of plastic waste to develop high added value materials, also known as upcycling, is a useful strategy towards the development of more sustainable materials. More specifically, the use of plastic waste as a feedstock ...
Opportunities for organocatalysis in polymer synthesis via step-growth methods
(Elservier, 2019-03-14)
Organocatalysis has emerged as an invaluable tool for polymer synthesis and has already demonstrated versatility for replacing organometallic catalysts in many polymerization reactions. The overall ease of removal and lower ...
Chemical Structure Drives Memory Effects in the Crystallization of Homopolymers
(ACS, 2020-06-11)
Although the study of melt memory has attracted much interest, the effect of polymer chemical structure on its origin has not been fully elucidated. In this work, we study melt memory effects by Differential Scanning ...
Solid–Solid Crystal Transitions (δ to α) in Poly(hexamethylene carbonate) and Poly(octamethylene carbonate)
(ACS, 2021-07-21)
Poly (hexamethylene carbonate) (PC6) and poly (octamethylene carbonate) (PC8) were studied under different crystallization conditions. Using differential scanning calorimetry (DSC), a new solid-solid transition, denoted α ...
