“…As duration exposure increases, an increase in surface oxygen levels is also observed. These results agree with previous studies [11][12][13][14][15]. However, previous investigations have also shown that the as-treated oxygen levels may not necessarily represent the functional groups participating in the chemical bonding between the treated surface and the epoxy infiltrate.…”

“…The infiltration of resin within these areas provides a more efficient stitching of weak plane directions as well as replaces an anisotropic material with a higher strength isotropic epoxy. However, numerous studies have shown that adhesives do not typically bond well to thermoplastics resins used in 3D printing, reducing their ability to transfer stress and achieve strong bonds for efficient utilization [11,12]. Plasma treatment has been shown to improve bonding in a number of polymer systems as well as a few structural composites materials systems with promising results [13,14].…”

Strengthening of plasma treated 3D printed ABS through epoxy infiltration

3D printed fused deposition modeling (FDM) material parts have distinct anisotropic mechanical properties based upon their as-built print orientation. The strength of material printed perpendicular to the deposition layers can be as low as 50% of values for injection molded parts due to less than optimum interlayer fusion, limiting their use for critical applications. The focus of this work is to present a novel way of utilizing design freedoms available in FDM to improve strength in weak orientations. Vertically processed FDM ABS parts were manufactured with cavities printed perpendicular to the interlayer direction and were subsequently plasma surface treated, filled with an epoxy resin, and mechanically tested. Plasma treatment was shown to beneficially modify the surface chemistry, which resulted in a 50% improvement in shear strength over untreated specimens. Samples that underwent plasma treatment and epoxy infiltration demonstrated a 130% increase in flexural strength over that of as-printed FDM material. The failure strain was also shown to increase by two-fold. The addition of milled carbon fiber (MCF) filler within the epoxy infiltrate was also evaluated and was shown to increase the flexural modulus by as much as 76% at 10 wt% loading levels, though negligible increases in strength were observed.

“…The peaks identified in the spectra at 1030 cm 21 and 700 cm 21 correspond to the aromatic CAH in-plane and out-of-plane bending, respectively [10]. The bands of the C@C bonds from styrene are located between 1400 cm 21 and 1600 cm 21 [11], and the peak of unsaturated trans C@C (vinyl) stretching in polybutadiene at 969 cm 21 are also observed [12][13][14]. The absorbance band corresponding to the 1,2-butadiene terminal vinyl CAH band in polybutadiene appeared at 911 cm 21 [12,15].…”

To commercially produce consumer products using engineering polymers, it is very important to control the physical properties of the material. However, quality control of the material is not easy because of many reasons such as cost reduction, cleaning issues, the use of scraps, etc. In many cases, even a small amount of foreign polymers can lead to product failures; however, analyzing such foreign polymers is difficult by using conventional analytical techniques. This article introduces a methodology to evaluate the durability of acrylonitrile–butadiene–styrene copolymers containing foreign polymers by using fracture mechanism maps (FMMs). In addition, the importance of the ductile‐to‐brittle transition temperature (DBTT) as a quantitative tool is discussed. In this article, the measurement of DBTT was proposed as a direct tool of characterizing polymer blends with similar chemical structure, and the concept of a FMM was applied as a qualitative tool to initiate the detailed investigation of fractures, as well as a quality control tool to sustain the fracture toughness of the final products.

The ability of non-equilibrium plasmas to modify surfaces has been known for many years. And a promising way to perform surface modifications without altering the bulk properties is plasma polymerization since this technique is versatile and can be applied to a wide range of materials. Plasma polymer films usually show good biocompatibility when compared to classical biomaterials. The possible biomedical use of plasma polymers motivates the study of their behavior during storage and in aqueous environment. Therefore, it is of major importance to understand the change of properties of these plasma polymers over time and when in contact with certain fluids. Recently, plasma polymer gradients (surfaces that display a change in at least one physicochemical property over distance) have attracted significant attention from the biomedical filed where the interaction of cells with a material surface is of major interest. This chapter discusses biomaterial functionalization via plasma polymerization focusing on their use in the biomedical field as well as their aging and stability behaviors. Plasma polymer gradients as valuable tools to investigate cell-surface interactions will also be reviewed.
