Adhesion in an aqueous environment is still a challenging topic. In recent years, the focus on biomimetic adhesives inspired by mussel proteins has greatly increased. The present paper focuses on a straightforward synthesis route for three biomimetic polymers with opportunity in a multi-gram scale and an overall yield of 83% over three steps. Two synthesized monomers combined with commercially available monomers are the basis for three different co-polymers with varying catechol content with nature inspired concentrations. Catechol-bearing monomers were protected prior to polymerization. |
Common linear polymers are known to undergo phase changes at the glass-transition temperature (Tg) and the melting point (Tm). In recent years, it has also been shown that molecules with long aliphatic side chains can give rise to a backbone-independent melting phenomenon, known as nanophase separation. This effect describes the self-assembly — independent of the polymer backbone — of alkyl side chains into semi-crystalline nanostructures. This work presents optimized, gram scale synthesis routes for dodecyl and octadecyl acrylamide and their respective homopolymers. Differential scanning calorimetry (DSC) experiments detected a broad endothermal signal for poly(n-dodecyl acrylamide) at − 29 °C and a narrower, more intense signal for poly(n-octadecyl acrylamide) at 34 °C. These sign... |
