Morphology and performance of nanosilica filler filled NR/NBR rubber composites
This study investigates the reinforcing effect of modified nanosilica (mNS) on natural rubber (NR) and acrylonitrile butadiene rubber (NBR) composites, with epoxidized natural rubber (ENR) used as a compatibilizer. Nanosilica (NS)-filled nanocomposites were developed and systematically analyzed for their morphological, rheological, and mechanical properties. Key findings indicate that increasing the mNS content from 0 to 10 phr enhances mechanical performance, including hardness, tear resistance, and abrasion resistance. Notably, the 70/30 NR/NBR blend with 6 phr of mNS exhibited a 128% increase in tensile strength and a 58% rise in stress at 100% elongation compared to unfilled NR/NBR. These improvements are attributed to the high surface area and uniform dispersion of mNS, which enhance interfacial interactions within the polymer matrix. Furthermore, higher mNS concentrations improved swelling resistance, reinforcing the nanofiller’s effectiveness in enhancing overall composite performance. These findings highlight the potential of mNS-reinforced NR/NBR composites for advanced elastomer applications.
期刊介绍：
The Journal of Rubber Research is devoted to both natural and synthetic rubbers, as well as to related disciplines. The scope of the journal encompasses all aspects of rubber from the core disciplines of biology, physics and chemistry, as well as economics. As a specialised field, rubber science includes within its niche a vast potential of innovative and value-added research areas yet to be explored. This peer reviewed publication focuses on the results of active experimental research and authoritative reviews on all aspects of rubber science.
The Journal of Rubber Research welcomes research on:
the upstream, including crop management, crop improvement and protection, and biotechnology;
the midstream, including processing and effluent management;
the downstream, including rubber engineering and product design, advanced rubber technology, latex science and technology, and chemistry and materials exploratory;
economics, including the economics of rubber production, consumption, and market analysis.
The Journal of Rubber Research serves to build a collective knowledge base while communicating information and validating the quality of research within the discipline, and bringing together work from experts in rubber science and related disciplines.
Scientists in both academia and industry involved in researching and working with all aspects of rubber will find this journal to be both source of information and a gateway for their own publications.
