Summary
MXene enhances natural rubber
Area of Science:
- Materials Science
- Polymer Chemistry
Background:
- Long-term thermo-oxidative resistance is crucial for elastomer applications.
- Conventional antioxidants often fail to provide sustained protection.
Purpose of the Study:
- To develop elastomers with enhanced long-term thermo-oxidative resistance.
- To investigate the use of MXene as a protective additive in natural rubber (NR).
Main Methods:
- Incorporation of MXene into a natural rubber matrix.
- Evaluation of thermo-oxidative resistance through tensile strength retention after aging.
Main Results:
- NR/MXene composites demonstrated superior long-term thermo-oxidative resistance compared to conventional antioxidants.
- After three days of thermo-oxidative aging, NR/MXene retained 63% of its tensile strength (19 MPa).
- MXene effectively scavenges oxygen and free radicals, and inhibits oxygen diffusion.
Conclusions:
- MXene is a promising additive for creating elastomers with exceptional long-term thermo-oxidative stability.
- This strategy offers a universal approach for designing advanced elastomers.
- The study expands the application potential of MXene in material science.

2.4K
Recently, the development of olefin metathesis polymerization advanced the field of polymer synthesis. Simply put, the reorganization of substituents on their double bonds between two olefins in the presence of a catalyst is known as the olefin metathesis reaction. The use of metathesis reaction for polymer synthesis is called olefin metathesis polymerization.

00:53Olefin Metathesis Polymerization: Acyclic Diene Metathesis (ADMET)
2.1K
Acyclic diene metathesis polymerization or ADMET polymerization involves cross-metathesis of terminal dienes, such as 1,8-nonadiene, to give linear unsaturated polymer and ethylene. As ADMET is a reversible process, the formed ethylene gas must be removed from the reaction mixture to complete the polymerization process.
Similar to cross-metathesis, ADMET also involves the formation of metallacyclobutane intermediate by [2+2] cycloaddition of one of the double bonds of a terminal diene with...

01:20Radical Autoxidation
2.7K
The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...

Hyperthermophilic archaea are a group of extremophiles thriving at temperatures above 80°C, often in hydrothermal vents and volcanic soils where conditions surpass the boiling point of water. At such temperatures, proteins, membranes, and DNA in most organisms degrade, but hyperthermophiles have evolved remarkable adaptations to maintain stability and function.Unique Cellular FeaturesHyperthermophilic membranes are composed of a monolayer of biphytanyl tetraether lipids, which resist...
