Lignin amination for bio-modfied epoxy resins and evaluation of suitable charcterization methods

This thesis unveils novel as well as optimized synthetic pathways for a one-step amino-functionalization of lignin material via Mannich reaction in order to form a bio-based curing agent for epoxy resins. The resulting amino-modified lignin derivatives were characterized explicitly and were optimized for utilization as amino-hardener for epoxy resins. This opens a new area of interest for incorporating lignin material as functionalized additive into epoxy resins. Thereby the benefit of biomass such as lignin can be increased and novel applicati ...
