Mechanochemical Responsiveness in Single and Double Network Hydrogels and the Mechanical Functionalization of Dual Mechanophore Networks

Alaa Ajam

Hydrogels capable of combining mechanical robustness with mechanochemical responsiveness hold significant promise for next generation biomaterials, yet the relationships between network architecture, reinforcement strategy, and activation behaviour remain poorly understood. This thesis systematically investigates how distinct reinforcing networks, mechanophore chemistries, and loading …

Stretch activated molecule immobilization in disulfide linked double network hydrogels

Yuwan Huang, Zihao Li, Chavinya D. Ranaweera, Pavithra Bhakthi Jayathilaka et autres

Inspired by how forces facilitate molecule immobilization in biological tissues to provide localized functionalization, tough hydrogel networks with stretch activated mechanochemistry are developed by utilizing disulfide bonds as dynamic covalent crosslinks. Specifically, disulfide linked polyethylene glycol hydrogels are reinforced with a second …

Improving the bioactivity and mechanical properties of poly(ethylene glycol)-based hydrogels through a supramolecular support network

Yuzhu Liu, Md Shariful Islam, Anna Bakker, Zihao Li et autres

formation of nanofiber networks can tune the stiffness of PEG-based hydrogels, while also imparting shear thinning, stress relaxation, and self-healing properties. The hybrid networks show enhanced toughness and durability under tension, providing scope for use in load bearing applications. A small quantity …

Mechanical and biological behavior of double network hydrogels reinforced with alginate versus gellan gum

Alaa Ajam, Yuwan Huang, Md Shariful Islam, Kristopher Alan Kilian et autres

Alginate and gellan gum have both been used by researchers as reinforcing networks to create tough and biocompatible polyethylene glycol (PEG) based double network (DN) hydrogels; however, the relative advantages and disadvantages of each approach are not understood. This study directly compares …
