Summary: This study evaluated the performance of Terminal Blend rubberized asphalt (TBRA) and SBS composite modified asphalt with different modification formulas. The results showed that adding 2% SBS to TBRA mixture can enhance rutting resistance and moisture resistance without affecting low-temperature performance. Furthermore, the chemically active SBS polymer can also strengthen the mixture by participating in polymer crosslinking networking with rubber molecules from the TB process.

Summary: Starch is a convenient and economically important polymer in the food and processing industry. However, native starches have limited applications for industrial usage. Therefore, starch modification is carried out to enhance positive characteristics and eliminate limitations. This review summarizes possible starch modifications and their corresponding applications, both within and outside the plant system (physical, chemical, and enzymatic). Furthermore, it highlights the implications of adjusting different starch properties.

Summary: Uniform dispersion of metal oxide-like zirconia in elastomeric matrix is essential for proper reinforcement. In this study, three different surface modifiers were employed to modify sol-gel derived zirconia and their effects on the properties of zirconia-filled nitrile rubber composite were investigated. The results show that tris (hydroxymethyl) aminomethane (Tris) is a potential surface modifier for zirconia, which can improve the thermal stability and tensile strength of the composite.

Summary: This study investigates a new surface modification method using silane and sulfenamide accelerators to enhance the interaction between silica and rubber. The results show that the modified silica has significantly improved reinforcement efficiency compared to conventional silica surface modification. Particularly, modifying silica with GPTMS and TBBS shows better results in terms of crosslink density and mechanical properties. The modified silica reduces the deformation of rubber and improves its stiffness, making it suitable for high performance rubber production.

Summary: In this study, rubber antioxidant poly(1,2-dihydro-2,2,4-trimethylquinoline) (RD) was used as an organic surface modifier of graphene oxide (GO) to develop highly anti-aging rubber composites. The RD was chemically bonded to the GO surface and effectively reduced the oxygen-containing groups. The modified GO showed improved dispersion in styrene-butadiene rubber (SBR) matrix and enhanced interfacial interaction with rubber chains, leading to superior mechanical performance and thermal conductivity of SBR/GO-RD composites. Moreover, the SBR/GO-RD composites exhibited exceptional long-term thermal-oxidative aging resistance, making them suitable for harsh service conditions.

Summary: An investigation showed that grafting polysaccharide agarose onto silicone rubber surface effectively inhibits bacterial adhesion and growth, improving the performance of medical devices. The modified silicone rubber surfaces demonstrated reduced water contact angle, successfully limiting bacterial adherence. After 10 days of simulated dynamic microenvironment in vivo, the durability and stability of the coating were observed, indicating a long service life. This modification method retains the biocompatibility of silicone rubber and opens new applications in the field of biomedical materials.

Summary: The dual modification using ozone and dry heating treatment for cassava starch resulted in changes in surface fissures, amorphous domains, oxidation level, and molecular size distribution, leading to starches with different properties. The sequence of treatments was crucial for the hydrogel properties, with different sequences resulting in gels of varying strengths. This dual modification method has the potential to produce specific modified starch with expanded applications compared to isolated treatments.
