With the aim of enabling the easy spinning of polysulfonamide (PSA) fibers, FFL-13 oil was successfully prepared. Specific resistance, the coefficient of friction, carding machine, electrostatic, cohesion, scanning tunneling microscopy (STM), and Fourier transform infrared (FTIR) spectroscopic analyses were conducted in this study. Results showed that increase in oil concentration, ambient temperature, and humidity induces decrease in PSA fiber-specific resistance and gradual increase in the antistatic property. Relatively high oil concentration and ambient humidity may cause fibers to become sticky and show increased roller winding. As oil concentration increased, fiber cohesion increased and fiber gliding properties showed an initial increase and subsequent decrease. The ideal oil concentration was determined to be 0.6%. This study proves that STM may effectively be used to determine the optimal oil concentration.

To investigate how plasma treatment affected the surface structure and adhesion to polypropylene matrix and unsaturated polyester matrix, green abaca fibers were treated by low temperature plasma under different plasma processing parameters including treatment time, output power, and working gas. Abaca fibers were characterized by atomic force microscope, X-ray photoelectron spectroscopy, contact angle and interfacial shear strength. The results of contact angle and interfacial shear strength were consistent with the changes in surface roughness and the atomic ratio of the plasma treated abaca fibers with treatment time, output power, and working gas. It was concluded that the surface roughness and atomic ratio played a major role in the adhesion improvement of the plasma treated abaca fibers to polypropylene matrix and unsaturated polyester matrix due to the mechanical interlocking and chemical bonding, respectively. The geometrical potential theory was adopted to elucidate the mechanism of the adhesion property.

“…Recently, to overcome the limitations of the poor adhesion of high-performance fibers, a variety of techniques have been used, such as the acid oxidation treatment, alkali solution treatment, gas-phase oxidation, heat treatment, polymerization treatment, cryogenic treatment, and plasma treatment [5,12,13,14,15,16,17,18,19]. Among these methods (see Table S1), plasma treatment only works on the uppermost layer of the material without compromising the bulk properties.…”

Abstract:Interface issues urgently need to be addressed in high-performance fiber reinforced composites. In this study, different periods of O 2 plasma treatment are proposed to modify twist-free polyimide (PI) filaments to improve hydrophilicity and mechanical and interfacial properties. Feeding O 2 produces chemically active particles to modify the filament surface via chemical reactions and physical etching. According to the X-ray photoelectron spectroscopy (XPS) results, the PI filaments exhibit an 87.16% increase in O/C atomic ratio and a 135.71% increase in the C-O functional group after 180 s O 2 plasma treatment. The atomic force microscope (AFM) results show that the root mean square roughness (Rq) of the treated PI filaments increases by 105.34%, from 38.41 to 78.87 nm. Owing to the increased surface oxygenic functional groups and roughness after O 2 plasma treatment, the contact angle between treated PI filaments and water reduces drastically from the pristine state of 105.08 • to 56.15 • . The O 2 plasma treated PI filaments also demonstrate better mechanical properties than the pristine PI filaments. Moreover, after O 2 plasma treatment, the adhesion between PI filaments and poly(amic acid) (PAA) is enhanced, and the tensile strength of the polyimide/poly(amic acid) (PI/PAA) self-reinforced composites increases from 136 to 234 MPa, even causing the failure mode of the composite changes from adhesive failure to partly cohesive failure.
