3D printing with biobased epoxidized formulations based on vegetable oils with dynamic polymer network properties
Vegetable-oil based epoxy formulations were investigated as 3D-printing materials with dynamic polymer network properties. DPN systems demonstrated successful 3D printability and were proven to be thermally reprocessable.

Synergistic reinforcement of Diels–Alder cycloadducts with hydrogen bonding interactions in recyclable dual-dynamic polyurethane networks
Here we report a facile strategy to prepare dual-dynamic networks (DDNs) comprising Diels–Alder (DA) covalent bonds and non-covalent hydrogen bonds which combine excellent mechanical properties and creep resistance with facile processability.
Stimuli-responsive liquid cell scaffold: reversible viscoelasticity switching of a polymer in an ionic liquid by visible-light
Cell culture at liquid|liquid interfaces has attracted attention in mechanobiology. A visible-light-responsive polymer solution in a non-cytotoxic ionic liquid reversibly switches viscoelasticity, offering a new platform for liquid cell scaffolds.
Enhancing the robustness of thiol–thioester covalent adaptable networks through reversible thiol–Michael masking
A reversible thiol-masking strategy reduces creep in thioester-based covalent adaptable networks while preserving dynamic exchange and reprocessability.
Efficient catechol functionalization of high oleic sunflower oil for the preparation of fully biobased and extrudable acetal CANs
A renewable catechol containing vegetable oil-based polyol was synthesized to prepare acetal CANs featuring good reprocessability and compatibility with extrusion.

Exploring transamidation and chemical recycling of β-amino amide-derived covalent adaptable networks
This study explores a newly identified transamidation exchange in the β-amino amide dynamic covalent chemistry and the chemical recycling of β-amino amide-derived covalent adaptable networks.
Interpenetrating vitrimers based on dioxaborolane metathesis and imine-aldehyde exchange
We report a simple methodology to prepare interpenetrating vitrimers based on dioxaborolane metathesis and imine-aldehyde exchange. The interpenetrating vitrimers exhibit a combination of properties superior to those of the constituent vitrimers.
About this collection
About this collection: This themed collection, Guest Edited by Filip Du Prez (Ghent University, ORCID: 0000-0001-7727-4155), Christopher Bowman (University of Colorado, ORCID: 0000-0001-8458-7723), Kristi Anseth (University of Colorado, ORCID: 0000-0002-5725-5691) and Tao Xie (Zhejiang University, ORCID: 0000-0003-0222-9717), presents the latest developments in dynamic polymer networks, focussing on both novel covalent and non-covalent chemistry approaches for their design. To fit in the scope of Polymer Chemistry, the collection aims to showcase advances in novel dynamic chemical reactions, insights into the interrelationship between dynamic chemistry and polymer behaviour, and finally sustainability-enabling design approaches to dynamic polymer networks without a direct application focus. This collection celebrates the progress and strong contribution of polymer science in this evolving area and aims to inspire new research.
