“…Before the treatment, the materials presented relatively flat surfaces with some reliefs due to the rolling manufacturing method. After plasma exposure, it can be observed an etching effect over the treated surface resulting in a small nodules formation, which is in agreement with previous reports [4,10,35].…”

The aim of this paper is to quantify the effects of dielectric barrier discharge (DBD) exposure on the physico-chemical and tribo-electric properties of polymers. The study was conducted in atmospheric air on polypropylene, polyethylene and polyvinyl-chloride. These three types of polymers are widely used in industry. The polymers were characterized by means of an optical profilometer, a fourier-transform infrared (FTIR) spectrometer and an electric charge measurement system. The latter is composed of a Faraday pail connected to an electrometer. The profilometer analyses showed that the DBD plasma treatment has increased the surface roughness of the three polymers. FTIR revealed that oxygen atoms and polar groups were grafted on their surfaces, thereby conferring them a hydrophilic character. The short (2 sec) DBD plasma treatment has considerably improved the electrostatic charge acquired by the polymers during electrostatic tribo-charging, while longer exposures conferred the polymer anti-static properties and decreased its tribo-charging capability. The correlation between the results of the physico-chemical analyses and the tribo-electric behavior has been discussed.

“…Meanwhile, during the chemical grafting, plasma or ultraviolet radiation is acted on C═C bonds of PP to form free radicals that are chemically active on the surface, then hydrophilic polar groups (such as C═O, COOH, OH) are introduced to make the material have certain wettability. This process is usually applied in the field of battery separators, surface modification of high‐performance fibers, and hydrophobic materials …”

Textiles with the function of directional water (sweat) transport play a pivotal role in regulating human thermal and wet comfort. Polypropylene nonwoven (PPNW) fabric has an excellent moisture (sweat) conduction due to its inert water absorption, which makes moisture be difficult to adhere on the PP fiber surface. Nevertheless, excessive hydrophobicity also affects the comfort of clothing materials, and thus it is significant to improve wettability of PP fiber used in the field of textile. In this study, it was reported a kind of composite fibrous mats with the function of directional water transport. The polymerization of acrylic acid (AAc) was grafted on the surface of plasma-treated PPNW (TPPNW) as the inner layer (TPPNW-AAc), which was able to improve the wettability of the PPNW surface. Polyacrylonitrile containing alumina nano-particles (PAN-Al 2 O 3 ) layer was deposited on the surface of TPPNW-AAc by electrospinning technology as the outer layer. The wettability difference between the inner and outer layers of the material was utilized to induce the push-pull effect to transport water from the TPPNW-AAc layer to the PAN-Al 2 O 3 layer. The surface wettability of the TPPNW-AAc layer and the performance of the directional water transport of composite fibrous mats were characterized systematically. Experimental results demonstrated that the composite fibrous mats showed the excellent accumulative one-way transport index (AOTI, 870%), remarkable overall moisture management capacity (OMMC, 0.8) when the contact angle of the TPPNW-AAc surface can be reduced from 119°to 30°, and decent wearability performance.

“…Polypropylene fiber reinforced concrete (PFRC) has been widely used in engineering construction. Currently, the research on adding PP fiber into other composites has attracted more attention (Mercado-Cabrera et al 2013;Yap et al 2013). In this paper, PP fiber was filled into PHB-lignocresol composite films with attention focused on the effect of PP fiber on the mechanical and thermal properties of composites.…”

Characterization of Polypropylene Fiber and Lignocresol Enhanced Poly(3-hydroxybutyrate) Composite Films

2016

The depletion of fossil resources and the environmental impact of petroleum-based plastic materials have driven a strong global interest in renewable biobased polymers and composites derived from natural resources. Since biodegradable polymers have their own drawbacks, it is often combined as a composite with other fillers. Polypropylene (PP)/Poly(3-hydroxybutyrate) (PHB) composite films and lignocresol (LC)/PP/PHB composite films were cast by blending methods. This study investigated the effects of the amounts of added PP fiber and LC on the mechanical and thermal properties in the corresponding composite films. The overall properties of LC/PP/PHB composite films were best with 8 wt.% PP fiber content and 3 wt.% LC content. The tensile strength (13.00 MPa) was up to 1.25 times that of the original PHB film (10.44 MPa), and the thermal properties of the composite films were improved by adding 3 wt.% LC. Thermogravimetry (TG) analysis indicated that the onset temperature (382.0 °C) rose by 50.7 °C compared with PP/PHB film (331.3 °C), and the residual mass was close to 0%.
