202476 citationsOpen accessUniversity of South Africa

In plain language

Polymer nanocomposites offer substantial potential beyond conventional materials. Combining different fillers into hybrid systems within polymer matrices improves material characteristics at both macro and micro levels through synergistic interactions. These hybrid filler approaches can boost mechanical, thermal, and electrical performance in composite and nanocomposite systems. Integrating diverse combinations, such as organic-inorganic, nano-micro, and bio-based fillers, creates functional advantages across multiple disciplines. Achieving these outcomes depends on understanding the methodologies used to incorporate hybrid fillers into matrices, alongside resolving the associated processing difficulties. Evaluating recent progress in hybrid filler characterisation and performance benefits outlines how these material combinations behave, providing direction for overcoming existing manufacturing challenges while identifying future research paths in composite materials science.

Key takeaways

  • Introducing hybrid fillers into polymer matrices enhances macro and micro properties through synergistic interactions between the fillers and polymers.
  • Hybridising fillers provides a practical pathway to improve the mechanical, thermal, and electrical properties of composite materials.
  • The approach incorporates varied combinations, including organic-inorganic, nano-micro, and bio-based fillers.
  • Performance advantages depend on the specific strategies and methodologies used to incorporate hybrid fillers into polymer matrices.

Why it matters

Traditional single-material composites often struggle to meet demanding multi-property requirements. Hybridising different fillers, including sustainable bio-based or nano-scale variants, allows developers to simultaneously upgrade the strength, heat resistance, and electrical conductivity of polymers. Understanding these synergies helps guide the design of multifunctional materials tailored for next-generation engineering requirements across various industrial sectors.

Commercialisation angle

The abstract points to prospective applications across various technical disciplines benefiting from improved thermal, electrical, and mechanical performance. Potential users include manufacturers developing advanced polymer composites incorporating bio-based, nano-micro, or organic-inorganic hybrid fillers. As a review examining methodologies, performance gains, and associated technical challenges, the work represents early-stage foundational research rather than a validated, near-market commercial formulation.

Abstract

Nanocomposites with polymer matrix provide tremendous opportunities to investigate new functions beyond those of traditional materials. The global community is gradually tending toward the use of composite and nanocomposite materials. This review is aimed at reporting the recent developments and understanding revolving around hybridizing fillers for composite materials. The influence of various analyses, characterizations, and mechanical properties of the hybrid filler are considered. The introduction of hybrid fillers to polymer matrices enhances the macro and micro properties of the composites and nanocomposites resulting from the synergistic interactions between the hybrid fillers and the polymers. In this review, the synergistic impact of using hybrid fillers in the production of developing composite and nanocomposite materials is highlighted. The use of hybrid fillers offers a viable way to improve the mechanical, thermal, and electrical properties of these sophisticated materials. This study explains the many tactics and methodologies used to install hybrid fillers into composite and nanocomposite matrices by conducting a thorough analysis of recent research. Furthermore, the synergistic interactions of several types of fillers, including organic-inorganic, nano-micro, and bio-based fillers, are fully investigated. The performance benefits obtained from the synergistic combination of various fillers are examined, as well as their prospective applications in a variety of disciplines. Furthermore, the difficulties and opportunities related to the use of hybrid fillers are critically reviewed, presenting perspectives on future research paths in this rapidly expanding area of materials science.
