Summary
Lignin, a renewable aromatic chemical, can be used to create sustainable polymers from depolymerized building blocks. This review explores recent advances in using lignin monomers and bio-oils for thermosetting materials like epoxy resins.
Area of Science:
- Polymer Chemistry
- Sustainable Materials Science
- Biomass Valorization
Background:
- Lignin is an abundant, renewable source of aromatic chemicals for polymer synthesis.
- Technical lignins present challenges in polymer development due to heterogeneity and poor solubility.
- Low molecular weight lignin derivatives (monomers, bio-oils) offer improved homogeneity and functionality.
Purpose of the Study:
- To review recent advancements in polymeric materials derived from lignin-based model compounds and depolymerized lignin bio-oils.
- To focus on the development of sustainable thermosetting materials.
- To identify strategies for utilizing lignin as a replacement for petroleum-derived aromatics in polymers.
Main Methods:
- Review of literature on polymeric materials synthesized from lignin model compounds.
- Analysis of studies utilizing lignin-derived bio-oils as polymer feedstocks.
- Focus on thermosetting resins including epoxy resins, polyurethanes, and phenol-formaldehyde resins.
Main Results:
- Lignin monomers and bio-oils enable greater substitution of non-renewable components in polymer formulations.
- Research shows significant overlap in using model compounds and bio-oils for epoxy resins, polyurethanes, and phenol-formaldehyde resins.
- Challenges remain in the production, separation, and processability of lignin-based feedstocks.
Conclusions:
- Depolymerized lignin building blocks offer a promising route to sustainable aromatic polymers.
- Further research is needed to overcome production and processing challenges for industrial viability.
- Lignin-based polymers represent a key strategy for reducing reliance on petroleum-derived chemicals.

4.0K
Actin filaments (F-actin) are composed of actin subunits. The dissociation of actin monomers can occur from either end of F-actin. The rate of dissociation is faster from the minus-end or the pointed end, where the actin subunits exist with a bound ADP, together known as ADP-actin. The depolymerization of F-actin is aided by proteins, including the actin-depolymerizing factor (ADF) and cofilin family of proteins, gelsolin, and glia maturation factor (GMF).

The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the...

All living things are formed mostly of carbon compounds called organic compounds. The category of organic compounds includes both natural and synthetic compounds that contain carbon. Although a single, precise definition has yet to be identified by the chemistry community, most agree that a defining trait of organic molecules is the presence of carbon as the principal element, bonded to hydrogen and other carbon atoms. However, some carbon-containing compounds such as carbonates, cyanides, and...

Pure substances consist of only one type of matter. A pure substance can be an element or a compound. An element consists of only one type of atom, while a compound consists of two or more types of atoms held together by a chemical bond.
Elements
Elements are classified as atomic or molecular based on the nature of their basic units. They are unique forms of matter with specific chemical and physical properties that cannot break down into smaller substances by ordinary chemical reactions. There...
