Enthused by the ever growing demand for sustainable and green based materials in responding to applications based on macromolecules, an attempt was made in seeking a bio‐resin (Terpene). Herein, we report the functionalization of bio‐resin with natural rubber (NR) to produce new sustainable and greener functional polymer. Bio‐resin functionalized NR was prepared by melt mixing using di(2‐tert butyl peroxy isopropyl) benzene initiator. Structure elucidation of the bio‐resin functionalized NR was established by proton nuclear magnetic resonance and Fourier transform infrared spectroscopy, respectively. Bio‐resin functionalized NR facilitates the augmented interaction with highly dispersible silica. Amended state of highly dispersible silica dispersion has been achieved in the absence of toxic process oil, expensive silane coupling agent and conventionally used zinc oxide. Remarkable improvement in overall properties corroborated with various meticulous characterization including nanoindentation, rheological, physico‐mechanical and small angle X‐ray scattering using Becauge model, etc. The dynamic mechanical properties of the greener polymer demonstrated low rolling resistance coupled with high traction. More decisively, the macromolecule system toned up sparingly in the presence of the bio‐resin. Our contribution facilitates a novel avenue to develop sustainable high‐performance elastomeric macromolecule. Copyright © 2017 John Wiley & Sons, Ltd.

“…When the filling content is higher, the elongation at the break of SiO 2 +AF/NR decreases faster, and the gap between SiO 2 +AF/NR and SiO 2 +AF/NR is more obvious. The probable reason is that physically mixing SiO 2 particles undergo aggregation due to their physicochemical surface properties [ 48 ], and numerous stress concentration regions that can propagate the cracks at lower stress appear. What is more, the interfacial adhesion between the smooth AF and the NR matrix is weak, which makes it easy for the AF to be pulled away during rubber composite stretching, and thus results in the increased stress concentration of the composites.…”

A rivet–inspired method of decorating aramid fiber (AF) with silica particles (SiO2) is proposed to produce SiO2@AF hybrid materials that have largely enhanced interfacial interaction with the rubber matrix. AF was firstly surface-modified with polyacrylic acid (PAA) to obtain PAA–AF, and SiO2 was silanized with 3-aminopropyltriethoxysilane to obtain APES–SiO2. Then, SiO2@AF was prepared by chemically bonding APES–SiO2 onto the surface of PAA–AF in the presence of dicyclohexylcarbodiimide (DCC) and 4-dimethylaminopyridine (DMAP). With the incorporation of SiO2@AF into the rubber matrix, SiO2@AF hybrid materials with high surface roughness can play a role as ‘rivets’ to immobilize large numbers of rubber chains on the surface. The tear strength and tensile strength of rubber composite that filling 4 phr SiO2@AF are dramatically increased by 97.8% and 89.3% compared to pure rubber, respectively. Furthermore, SiO2@AF has superiority in enhancing the cutting resistance of rubber composites, in contrast with unmodified AF and SiO2. SiO2@AF is suitable to be applied as a novel reinforcing filler in rubber composites for high performance.

β-Myrcene, a bio-based monoterpene derived from plants, was introduced to replace butadiene in the solution-polymerized styrene-butadiene rubber by using the conventional anionic copolymerization technique. The anionic copolymerization of β-myrcene was found to be stoichiometric and controllable. A series of solution-polymerized styrene-myrcene-butadiene rubber (S-SMBR) with 100% conversion, high-molecular weight (150 000-200 000 Da), low polydispersity, and uniform compositions was obtained. The glass transition temperature of S-SMBR exhibited imperceptible variation with different myrcene/butadiene ratios. Interestingly, the introduction of such a long nonpolar pendant group containing isopropylidene could greatly improve carbon black dispersibility in the rubber. Furthermore, the wet skid resistance of the rubber could be improved without impairing its low rolling resistance. The tensile strength of S-SMBR was found to be higher than that prepared by radical emulsion copolymerization. The S-SMBR prepared by anionic solution copolymerization is thus a promising material for tires to attain sustainable development. HIGHLIGHTS• A bio-based monomer was successfully introduced to replace diene part in SBR through anionic polymerization.• Carbon black dispersibility in the rubber was greatly improved.• The wet skid resistance of the rubber could be improved without impairing its low rolling resistance.• Robust tensile behaviors were obtained compared with the rubber prepared by radical emulsion polymerization.
