“…stress and strain) has been confirmed in many studies [5][6][7][8][9][10]. These slip additives can modify the surface structure of different materials, from model substrates such as silica [5] or mica [11] to raw industrial materials such as polyolefin films [9] or fibres [12]. The additives can be introduced to the material externally via physical adsorption using different methods, e.g.…”

“…Erucamide (13-cis-docosenamide, C22H43NO; Figure 1) is one of the most widely used fatty acid amide slip additives in polyolefin manufacturing [9,11,12,[14][15][16], reportedly reducing the coefficient of friction (CoF) down to 0.2 [9,17]. Its stability, low toxicity and transparency, along with its extraordinary slip properties attainable at low concentrations, find erucamide used as an antifouling [18], antifogging [19], angiogenic [20,21], antiviral [22], dispersing [23][24][25][26], or scratch resistant [27][28][29] agent in a wide spectrum of applications ranging from food packaging, automobile and textile industries to hygiene and healthcare products.…”

“…Erucamide migration [6,14,30], distribution [11] and nanomechanical properties [5,9,12,17], along with the effect of the erucamide concentration [15,31] and ambient temperature [32,33] on its surface structure [9], has been widely studied. From these studies, it is clear that the slip-additive surface assembly and the resultant performance depend on the additive deposition method and concentration as well as the substrate surface chemistry.…”

Carbon fibers were surface treated with supercritical water/nitrate system to improve the interfacial adhesion of the carbon fiber/epoxy composite. The surface chemistry analysis showed that oxygen functional groups on the surface of the carbon fibers increased after treatment, which were mainly carbonyl and carboxyl groups. The surface microstructure observation indicated that the treatment obviously increased the surface roughness of the carbon fibers. Surface energy of the treated carbon fibers also increased. The increased functional groups, surface roughness and surface energy were beneficial to enhance the interfacial adhesion of the carbon fiber/epoxy composite. Compared with the untreated carbon fibers, the strength loss of the treated carbon fibers was less than 3% and the other mechanical properties were almost unchanged. The caclulated interfacial fracture energy and the interfacial shear strength of the treated carbon fiber/epoxy composite were enhanced by 19% and 29%, respectively, compared with the untreated carbon fiber/epoxy composite. In summary, supercritical water/nitrate treatment is a potential method for changing the inert surface of carbon fibers to improve the interfacial adhesion between carbon fibers and matrix.

“…[13][14][15][16] Previous research has provided suggestions for tailoring the softness of PP micro-nanofibrous fabrics. 17,18 Generally, adding functional polymers during the meltblowing process has been an effective and facile strategy to improve the performance of PP micro-nanofibrous fabrics. 19 Adding elastic polymers to create the blend, for example, propylene-based elastomer 20 and thermoplastic polyurethane, 21 can improve the elasticity performance of PP fabrics.…”

The softness of polypropylene (PP) fabrics, which is related to fiber properties and fabric structure, is a pivotal perception for their application in skin contacts. However, tailoring the softness of PP fabrics remains challenging. The effects of mixing different percentages of polyethylene (PE) and PP during the melt-blowing process on the polymer properties and morphology characteristics, including the softness, preparation, and characterization of the micro-nanofibrous fabrics were determined. Rheological tests and differential scanning calorimetry results showed that the addition of PE helped destroy the crystalline integrity of PP. Moreover, scanning electron microscopy images depicted a fluffy structure consisting of micro-nanofibers with average diameters ranging from 1.3 to 3.2 μm. Furthermore, the softness scores ranged from 70.39 to 83.11 by changing the die temperature and PE mass ratio by applying a response surface model. Consequently, this micro-nanofibrous fabric may become a good material for skin contacts, such as baby diapers, feminine sanitary, and other personal hygiene uses.
