The escalating demand for multifunctional and advanced materials for growing industries has turned scientific exploration to graphene-based hybrid filler polymer composites. The introduction of graphene with other fillers into polymer matrices results in astonishing properties and thus has gained significant attention in recent years. This study addresses the significance of graphene-based hybrid filler polymer composites in progressive materials science and engineering. The paper encloses some traditional and current preparation techniques employed in the fabrication of composites and a comprehensive review of successfully prepared graphene hybrid polymer composites with enhanced mechanical, thermal, and electrical properties reported in published research. The role of different factors, e.g., filler type, aspect ratios, filler-matrix compatibility, dispersion effects, homogeneity, filler orientation through polymer matrices, and curing conditions, are summarized. Finally, the applications in heavy industries, e.g., aerospace, electronics, energy storage, and automotive sectors were also analyzed. We hope this study will serve as a practical resource for new researchers and practitioners to understand and harness the full potential of these composites in various scientific and industrial fields.

Biodegradable polymers, such as poly(ε-caprolactone) (PCL), have gained significant attention due to their potential applications in various fields. To enhance the properties of PCL, researchers have focused on developing composites by blending it with other polymers or incorporating bioactive agents. One approach is the synthesis of PCL with oleic acid (OA), a natural fatty acid, resulting in improved mechanical, thermal, and in vitro activities. In this study, the synthesis of PCL modified with oleic acid was investigated using Maghnite-H+ as a sustainable heterogeneous solid catalyst. The Maghnite clay was treated with sulfuric acid to activate its catalytic properties. The impact of various synthesis conditions, such as the temperature and duration of the reaction, as well as the quantity of catalyst used, is evaluated using a response surface technique. This method employs a central composite design with three factors, each having three different levels. The resulting PCL-OA composite showed enhanced properties and in vitro activities, including antioxidant and antibacterial properties. The antioxidant activity was evaluated using the DPPH radical scavenging assay, where PCL-OA exhibited a significant increase in inhibition rate. Ascorbic acid (vitamin C) was used as a standard, demonstrating remarkable scavenging activity. The enhanced scavenging activity of PCL-OA can be attributed to the chemical modifications occurring during the grafting process of PCL with oleic acid. The antimicrobial properties of PCL-OA were investigated against various microorganisms, and the results showed different sensitivities of the strains to the compounds. Combinations of caprolactone, oleic acid, and PCL-OA resulted in increased antimicrobial activity for most of the tested strains, indicating a synergistic effect. Physicochemical characterization techniques, including FTIR and NMR, confirmed the successful synthesis and structural changes of PCL-OA. Thermal stability analysis revealed the decomposition behavior of the composite.

Endüstriyel organik çözücü emisyonlarının ve petrol sızıntılarının sık görülmesi ile yüksek verimli yağ-su ayırma malzemelerinin geliştirilmesi büyük önem kazanmıştır. Bu çalışmada, yağ-su ayırma için polikaprolakton/polihidroksibütirat (PCL/PHB) nanolifli matlar paslanmaz çelik elek yüzeyler üzerinde tek basamaklı elektroeğirme yöntemi ile başarılı bir şekilde üretildi. Elde edilen biyobazlı lifli matların yüzey morfolojisi Alan Emisyonlu Taramalı Elektron mikroskopisi (FE-SEM) ile analiz edildi. Ayrıca hazırlanan tüm örneklerinin kimyasal yapılarını açığa çıkarmak ve ıslanma özelliklerini incelemek için Fourier Dönüşümlü Kızılötesi spektroskopisi (FT-IR) ve temas açısı ölçüm cihazı kullanıldı. Hazırlanan yeşil PCL/PHB nanolifli membranların ıslanabilirliği üzerine yapılan çalışmalar, membran yüzeylerinin mükemmel hidrofobik ve süperoleofilik özelliğe sahip olduklarını gösterdi. Ölçülen su temas açısı değerleri biyopolimer katkı oranlarına ve elek boyutuna bağlı olarak değişkenlik gösterdi. Paslanmaz çelik elekler üzerinde elde edilen PCL/PHB biyokompozit nanofiber matların maksimum su temas açısı değeri 144.8° olarak ölçülürken yağ temas açısı değeri ise sıfıra yakın olarak ölçüldü. Çelik elekler üzerinde elde edilen hidrofobik ve süperoleofilik PCL/PHB biyonanolifli membranlar doğrudan yerçekimi güdümlü yağ-su ayrımı için kullanıldı ve ekstra herhangi bir kuvvet veya kimyasal reaktif kullanmaksızın ağ boyutuna ve biyopolimer karışım oranlarına bağlı olarak en yüksek %97.4 'lük yüksek bir ayırma verimliliği değeri gözlendi.
