Epoxy Cross-Linked Collagen and Collagen-Laminin Peptide Hydrogels as Corneal Substitutes

Journal of Functional Biomaterials, 2013
A bi-functional epoxy-based cross-linker, 1,4-Butanediol diglycidyl ether (BDDGE), was investigated in the fabrication of collagen based corneal substitutes. Two synthetic strategies were explored in the preparation of the cross-linked collagen scaffolds.

Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks

Macromolecular Rapid Communications, EarlyView.
Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.

Spent Artemisia arborescens as a Biowaste Filler for Melt‐Processed PBSA Biocomposites With Enhanced Disintegration and Aerobic Biodegradation

Polymer Composites, EarlyView.
Spent Artemisia arborescens biomass, recovered after essential‐oil steam distillation, was ground and melt‐compounded with PBSA (10 and 20 wt%), yielding biocomposites with accelerated biodegradation. ABSTRACT Artemisia arborescens is a Mediterranean shrub widely used for essential oil production, generating significant amounts of spent biomass after ...

A Strategic Approach to Improving Interfacial Interactions in TPU/POSS Composites via Ball Milling of POSS

Polymer Engineering &Science, EarlyView.
Ball‐milling promotes uniform POSS dispersion in the TPU matrix, markedly improving the mechanical performance of TPU‐POSS composites. ABSTRACT We synthesized TPU/POSS composites through a two‐step process involving the ball milling of POSS to reduce its particle size, followed by in situ polymerization of TPU to reinforce the material.
