Abstract

This data article introduces the utilization of thermally dynamic covalent bonds of lignin linkages such as β–O–4', Cα–O of β–5' phenylcoumaran, and β–β resinol to modify the thermomechanical properties of high loading lignin-nitrile rubber composites. These thermally active lignin linkages can be triggered at 180 °C to generate free-radicals for crosslinking reactions. The evolution of crosslinking density was measured in-situ using dynamic mechanical analysis and rheological characterization. The shape programmability and shape recovery of these composites were determined by both ex-situ and in-situ methods. The thermally modified composites exhibited excellent shape memory properties. The data in this article are related to our recent research article entitled “Responsive lignin for shape memory applications” (Nguyen et al., 2018).

Thermo-Responsive Polymers-Based on Source-Selective Lignins

Conference Nguyen, Ngoc A. ; Meek, Kelly ; Barnes, Sietske H. ; ...

In this study, thermomechanical properties of hardwood and softwood lignin-nitrile butadiene rubber composites were controlled by a thermal annealing process. The presence of thermally unstable linkages within the selected lignins provides free radical sources for crosslinking reactions. The measured dynamic mechanical properties demonstrated substantial improvement in glass transition temperatures (Tg) and storage moduli (E’) of 50 wt. % softwood lignin- and 50 wt. % hardwood lignin-rubber composites after thermal annealing at 180°C. An increase in Tg of approximately 18°C and more than 230% increasing E’ was achieved after annealing the 50 wt. % hardwood lignin-rubber for 5 h. The chemicalmore »« less

Responsive lignin for shape memory applications

Journal Article Nguyen, Ngoc A. ; Meek, Kelly M. ; Bowland, Christopher C. ; ... - Polymer

Here, we analyze thermally unstable lignin linkages that generate reactive sites and promote crosslinking reactions during thermal annealing at 180 °C. This results in significantly enhanced glass transition temperature (Tg). We use these characteristics of lignin to enhance interfacial reactivity of a lignin-based multiphase polymer synthesized by a dynamic shear process. An approximately 18 °C increase in Tg and more than 230% increase in storage modulus (E') are achieved by thermally annealing the 50 wt% hardwood lignin-nitrile rubber composite for 5 h at 180 °C. Tunable chemical and physical crosslinks within lignin and rubber resulted in shape programmability demonstrating excellentmore »« less

Structural Characterization of Lignin from Maize ( Zea mays L.) Fibers: Evidence for Diferuloylputrescine Incorporated into the Lignin Polymer in Maize Kernels

Journal Article del Rio, Jose C. ; Rencoret, Jorge ; Gutierrez, Ana ; ... - Journal of Agricultural and Food Chemistry

The structure of the phenolic polymer in maize grain fibers, with 5.5% Klason lignin content, has been studied. For this, the milled wood lignin (MWL) and dioxane lignin (DL) preparations were isolated and analyzed. The data indicated that the lignin in maize fibers was syringyl rich, mostly involved in β-aryl ether, resinol, and phenylcoumaran substructures. 2D NMR and derivatization followed by reductive cleavage (DFRC) also revealed the occurrence of associated ferulates together with trace amounts of p-coumarates acylating the γ-OH of lignin side chains, predominantly on S-lignin units. More interesting was the occurrence of diferuloylputrescine, a ferulic acid amide, whichmore »« less

A general method to improve 3D-printability and inter-layer adhesion in lignin-based composites

Journal Article Nguyen, Ngoc A. ; Bowland, Christopher C. ; Naskar, Amit K. - Applied Materials Today

Here, we report the utilization of a melt-stable lignin waste-stream from biorefineries as a renewable feedstock, with acrylonitrile-butadiene rubber and acrylonitrile-butadiene-styrene (ABS) polymer to synthesize a renewable matrix having excellent 3D-printability. While the initial low melt viscosity of the dispersed lignin phase induces local thermo-rheological relaxation facilitating the composite's melt flow, thermal crosslinking in both lignin and rubber phases as well as at the lignin-rubber interface decreases the molecular mobility. Consequently, interfacial diffusion and the resulting adhesion between deposited layers is decreased. However, addition of 10 wt.% of discontinuous carbon fibers (CFs) within the green composites not only significantly enhancesmore »« less

Fractionation of Lignin for Selective Shape Memory Effects at Elevated Temperatures

Journal Article Nguyen, Ngoc A. ; Bowland, Christopher ; Bonnesen, Peter V. ; ... - Materials

We report a facile approach to control the shape memory effects and thermomechanical characteristics of a lignin-based multiphase polymer. Solvent fractionation of a syringylpropane-rich technical organosolv lignin resulted in selective lignin structures having excellent thermal stability coupled with high stiffness and melt-flow resistance. The fractionated lignins were reacted with rubber in melt-phase to form partially networked elastomer enabling selective programmability of the material shape either at 70 °C, a temperature that is high enough for rubbery matrix materials, or at an extremely high temperature, 150 °C. Utilizing appropriate functionalities in fractionated lignins, tunable shape fixity with high strain and stressmore »« less
