Cellulose From Aloe Vera Plant Waste as Crosslinker for Vat 3D Printable Vitrimers: Toward a Circular Economy Approach in Additive Manufacturing

Macromolecular Materials and Engineering
The reduction of the environmental impact of photocurable resins, commonly used in vat 3D printing, is an urgent request. In order to truly enable vat additive manufacturing (AM) to adopt a circular economy approach, this can be done by both selecting ...

Amine-Cured Glycidyl Esters as Dual Dynamic Epoxy Vitrimers

It is of greater significance to develop amine-cured epoxy vitrimers than conventional epoxy-carboxylic acid vitrimers because amines are the most widely curing agents than carboxylic acids.
