Erucamide Effects on Single Fiber Crystal Structure and Mechanical Properties
Gubała, Dajana, et al. ACS nano 18.7 (2024): 5940-5950.
Synchrotron nanofocused X-ray diffraction (nXRD) with a 60 nm beam was employed to investigate the effects of erucamide on single-fiber crystal structure, linking nanostructural findings directly to single-fiber mechanical properties.
Experimental Protocol: Single polypropylene (PP) fibers and PP fibers containing 1.5 wt% erucamide (PP+ER) were scanned along 300 μm of fiber length and across the fiber cross-section at 100 nm step size. nXRD measurements identified crystallite size via Scherrer analysis, degree of crystallinity (Dc), and bimodal orientation of parent and daughter lamellae. Complementary single-fiber uniaxial tensile tests measured engineering tensile strength (σ), elongation at break (ε), Young's modulus (E), and toughness (T). DSC confirmed crystallinity differences via melting temperature.
Performance Evaluation: Erucamide significantly promoted fiber crystallinity: Dc increased from ~30% (PP) to 43-50% (PP+ER), with parent lamellae growing from ~175 Å to ~244 Å. The melting temperature rose from 149.1 °C to 160.7 °C. Mechanically, erucamide decreased tensile strength from 344 ± 25 to 192 ± 6 MPa and Young's modulus from 1.5 ± 0.3 to 1.2 ± 0.2 GPa, while increasing fracture strain from 71 ± 6% to 162 ± 6% and toughness from 153 ± 16 to 188 ± 8 J/m³. The mechanism was attributed to erucamide acting as an interlamellar lubricant, facilitating polymer chain disentanglement during stress-induced crystallization and reducing microfibril shear stress during plastic deformation.
Erucamide for Antidepressant and Anxiolytic Effects via HPA Axis Modulation
Li, Miao-Miao, et al. Neuroscience letters 640 (2017): 6-12.
Erucamide, a bioactive fatty acid amide structurally similar to oleoylethanolamide, was investigated for its potential antidepressant and anxiolytic effects in mouse behavioral models involving the hypothalamic-pituitary-adrenal (HPA) axis.
Experimental Protocol: Fifty male Kunming mice were randomly divided into five groups and orally administered vehicle (0.3% methyl cellulose), erucamide (5, 10, or 20 mg/kg), or fluoxetine (20 mg/kg, positive control) daily for 7 consecutive days. Behavioral tests included the forced swimming test (FST), tail suspension test (TST), open field test (OFT), and elevated plus-maze test (EPMT). Serum adrenocorticotrophic hormone (ACTH) and corticosterone (CORT) levels were measured by ELISA. Total antioxidative capacity (T-AOC) was determined by ultraviolet spectrophotometry.
Performance Evaluation: A 7-day erucamide administration (5-20 mg/kg) significantly reduced immobility time in both FST (p = 0.001) and TST (p = 0.001) compared with vehicle control, without affecting locomotor activity in the OFT. At 10 and 20 mg/kg, erucamide significantly increased the percentage of time spent in the OFT central area (p = 0.001) and the ratio of open arm entries in the EPMT (p = 0.003). Biochemically, erucamide treatment significantly decreased serum ACTH (p = 0.005) and CORT (p < 0.001) levels, indicating positive modulation of HPA axis activity. T-AOC levels did not change significantly, suggesting the antidepressant mechanism was HPA-axis-mediated rather than antioxidant-dependent.
Erucamide Synergistic Anti-Friction Performance with N-PAN in Polyurea Grease
Liu, Qingchun, et al. RSC advances 15.58 (2025): 50408-50418.
Erucamide (ER) and N-phenyl-α-naphthylamine (N-PAN) were incorporated into polyurea grease to investigate their synergistic effects on tribological performance at elevated temperatures.
Experimental Protocol: Polyurea grease was prepared using PAO4 synthetic base oil and a thickener synthesized from MDI and cyclohexylamine. The optimized formulation contained 2 wt% ER and 1 wt% N-PAN. Tribological tests were conducted on a reciprocating tribometer (MFT-5000) with GCr15 steel blocks and Si3N4 balls at 25 °C, 75 °C, and 120 °C under 20 N load, 8 mm stroke, 1 Hz frequency for 30 min. Worn surfaces were analyzed by EPMA, FESEM, and EDS. 3D optical profilometry characterized wear tracks.
Performance Evaluation: The ER+N-PAN formulation reduced the average friction coefficient by approximately 32% compared with base polyurea grease, achieving optimal tribological performance at 75 °C with an average friction coefficient of 0.088. Surface wear on GCr15 steel decreased with increasing temperature, and samples lubricated with PG-ER-N(2,1) showed consistently less wear than base grease. ER molecules formed an ordered bilayer structure via hydrogen bonding between amide groups, filling base oil voids and converting sliding friction into rolling friction. N-PAN effectively inhibited oxidative degradation of the base oil by interrupting free-radical chain reactions, preserving film integrity.
