Summary
This study synthesized multi-walled carbon nanotubes (MWCNT) and epoxy resin composites. Adding MWCNT did not alter the glass transition temperature but reduced cure enthalpy in DGEBA/DDM systems.
Area of Science:
- Materials Science
- Polymer Chemistry
Background:
- Epoxy resins like DGEBA are versatile thermosets.
- Multi-walled carbon nanotubes (MWCNT) offer enhanced mechanical and thermal properties.
- Understanding composite behavior is crucial for advanced applications.
Purpose of the Study:
- To investigate the effect of MWCNT on the cure kinetics of DGEBA/DDM epoxy resin.
- To synthesize millimeter-long MWCNT using camphor/ferrocene pyrolysis.
- To evaluate changes in thermal properties and cure behavior.
Main Methods:
- Synthesis of MWCNT via camphor/ferrocene pyrolysis.
- Preparation of DGEBA/DDM epoxy resin composites with up to 1% MWCNT.
- Differential scanning calorimetry (DSC) to analyze cure kinetics and thermal properties.
Main Results:
- MWCNT were successfully synthesized with millimeter lengths.
- No significant change in the glass transition temperature (Tg) of the epoxy composite was observed.
- A reduction in cure enthalpy was detected with the addition of MWCNT.
Conclusions:
- MWCNT incorporation does not affect the glass transition temperature of DGEBA/DDM epoxy resins.
- MWCNT influence the cure process, leading to reduced cure enthalpy.
- Further research can explore optimizing MWCNT content for specific performance enhancements.
