Erucamide, a long-chain fatty acid amide, has been investigated as an additive to improve the tribological properties of greases used in roller bearings. In this study, lithium complex grease (LCG) and polyurea grease (PG) were modified with varying proportions of erucamide and N-phenyl-α-naphthylamine to assess their impact on grease performance. The formulations tested included different mass ratios of erucamide and N-phenyl-α-naphthylamine (0,0), (0,3), (1,2), (2,1), and (3,0).
The preparation process involved adding erucamide and N-phenyl-α-naphthylamine to the greases after cooling the reactor temperature to room temperature. The mixture was then stirred for 30 minutes to ensure even distribution before being processed through a three-roller grinder. The greases were named according to their compositions (e.g., PG-ER-N (e,n), where "e" is the mass fraction of erucamide, and "n" is the mass fraction of N-phenyl-α-naphthylamine).
The results indicated that the addition of erucamide enhanced the tribological performance of both LCG and PG. The grease formulations with erucamide and N-phenyl-α-naphthylamine exhibited improved lubricating properties, reducing friction and wear in roller bearing applications. This study highlights the potential of erucamide as a functional additive in enhancing the performance and durability of lubricating greases in industrial applications.

Erucamide has been explored as a functional additive in polydimethylsiloxane (PDMS)-based coatings to combat marine biofouling, a major issue affecting ship hulls and offshore structures. Biofouling increases frictional drag, leading to significant fuel consumption and maintenance costs. Developing eco-friendly, cost-effective anti-biofouling coatings is therefore essential.
In this study, erucamide was incorporated into PDMS prepolymer at varying concentrations (0.625-5 wt%) to fabricate hydrophobic surfaces with improved drag reduction properties. Erucamide was first dissolved in toluene at concentrations of 0-80 w/v% and mixed with PDMS prepolymer and curing agent at a 10:1 weight ratio. The resulting solutions were vortex-mixed and cast onto substrates such as glass slides and aluminum plates. Curing was carried out at 60 °C for 24 h, allowing toluene evaporation and matrix hardening.
The addition of erucamide enhanced surface hydrophobicity, crucial for minimizing biofouling adhesion. Higher erucamide content resulted in greater drag reduction, making the coatings more effective in marine environments. These findings highlight erucamide's potential as a key modifier in silicone-based antifouling coatings, contributing to sustainable and energy-efficient marine operations.

Erucamide has been explored as an additive in the development of low-friction coefficient (FCO) polymeric films for industrial applications. In this study, LLDPE films were enhanced with erucamide and montmorillonite nanoclay (Cloisite 20A) to improve the mechanical properties and surface characteristics of the films. The polymeric films were produced using a single screw balloon tube extruder, incorporating varying concentrations (5%, 10%, 15%) of erucamide and nanoclay.
The interspersion of erucamide molecules in the nanoclay structure was achieved by treating the nanoclay in an erucamide solution, which resulted in increased basal spacing. The nanocomposite films exhibited a decrease in the friction coefficient, indicating better surface smoothness and reduced resistance. Additionally, the films showed increased brightness, decreased opacity, and smoother surfaces, as evaluated by techniques like Transmission Electron Microscopy (TEM), Differential Scanning Calorimetry (DSC), and Atomic Force Microscopy (AFM).
The addition of 0.25% erucamide to the LLDPE matrix resulted in low FCO values, highlighting its potential in reducing friction and improving the performance of polymer films. This research demonstrates that erucamide is a promising additive for enhancing the properties of nanocomposite films used in various applications, particularly where low friction is essential.
