“…Several investigations have been reported on the effect of industrial contaminants on the morphology, mechanical properties and structure of glove material. In previous works [15][16][17][18][19][20][21][22][23][24], we reported that polymers and composites [16][17][18][19][20]22,23,[25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41] can be degraded by several aging agents such as heat, water, humidity, oxygen, ozone and various other environments factors [16][17][18][19][20][21][22][23][24]. The scission, crosslinking and plasticization of polymer networks may occur and led to severe deterioration of the mechanical and physicochemical properties of the material [42], which are quite important with regard their applications in various fields of mechanical engineering.…”

Butyl rubber-based composite (BRC) is one of the most popular materials for the fabrication of protective gloves against chemical and mechanical risks. However, in many workplaces, such as metal manufacturing or automotive mechanical services, its mechanical hazards usually appear together with metalworking fluids (MWFs). The presence of these contaminants, particularly at high temperatures, could modify its properties due to the scission, the plasticization and the crosslinking of the polymer network and thus lead to severe modification of the mechanical and physicochemical properties of material. This work aims to determine the effect of temperature and a metalworking fluid on the mechanical behavior of butyl rubber composite, dealing with crosslinking density, cohesion forces and the elastic constant of BRC, based on Mooney–Rivlin’s theory. The effect of temperature with and without MWFs on the thermo-dynamical properties and morphology of butyl membranes was also investigated. The prediction of service lifetime was then evaluated from the extrapolation of the Arrhenius plot at different temperatures.

“…In the alkaline treated P100 and PC90/10 fabrics, the surface roughness mean deviation value was higher than untreated fabrics. This occurred because the alkali treatment caused hydrolysis in the polyester fabric, resulting in a decreased fiber and yarn thickness, 25,26 and thus a higher surface roughness mean deviation values occurred as the thickness difference increased between the polyester and cotton single yarns. 27 On the other hand, in the case of alkaline treated C100 fabric, the surface roughness mean deviation value was lower than untreated cotton fabric.…”

Superhydrophobic fabric composed of polyester and cotton single yarns was developed by alkali treatment and thermal aging. During the alkali treatment to make the nano-roughness of the polyester fibers, micro-roughness also increased due to differences in the thicknesses of the two yarns arising from the increased polyester surface roughness and swollen cotton. The superhydrophobicity, with a static contact angle of 155.8 ± 3.2° and shedding angle of 11.1 ± 0.8°, was achieved with 90% polyester/10% cotton fabric treated with 20% alkali concentration for 20 min under applied tension, then followed by 24 h thermal aging at 130℃. The tensile strength of the superhydrophobic polyester/cotton fabric (28.7 MPa) was higher than that of 100% polyester fabric (20.1 MPa). The breathability of the superhydrophobic polyester/cotton fabric was improved compared with 100% polyester fabric. In durability assessment, a static contact angle of ≥150° was shown for the tape tests. Five times of repeated adhesion with a clothing tape cleaner were conducted for the five samples each. Although washing and dry-cleaning decreased contact angles to as low as 137.7°, a static contact angle of 150° was achieved by additional thermal aging (130℃, 24 h). We developed a superhydrophobic fabric mixed with polyester and cotton yarns by exploiting differences in the characteristics of the two yarns induced by alkali treatment, which causes fabric surface roughness, and thermal aging without the use of any chemicals. Moreover, this superhydrophobic fabric has improved breathability.

Atomic force microscopy (AFM) has been extensively used for the nanoscale characterization of polymeric materials. The coupling of AFM with infrared spectroscope (AFM-IR) provides another advantage to the chemical analyses and thus helps to shed light upon the study of polymers. In this perspective paper, we review recent progress in the use of AFM-IR in polymer science. We describe first the principle of AFM-IR and the recent improvements to enhance its resolution. We discuss then the last progress in the use of AFM-IR as a super-resolution correlated scanned-probe IR spectroscopy for chemical characterization of polymer materials dealing with polymer composites, polymer blends, multilayers and biopolymers. To highlight the advantages of AFM-IR, we report here several results in studying crystallization of both miscible and immiscible blends as well as polymer aging. Then, we demonstrate how this novel technique can be used to determine phase separation, spherulitic structure and crystallization mechanisms at the nanoscale, which have never been achieved before. The review also discusses future trends in the use of AFM-IR in polymer materials, especially in polymer thin film investigation.
