“…Also, the high peak power of fs lasers could induce a multiphoton absorption to ablate transparent materials [2]. Similar results were also obtained in the case of polymer [3][4][5][6]. With the advance of femtosecond laser technology and polymer science, femtosecond laser-polymer interaction has been attracting more and more attention, and has recently directed polymer applications to fabricating microelectronic components and optical devices, according to their specific thermal, electrical, mechanical and chemical properties [7].…”

Laser Surface Texturing of Polymers for Biomedical Applications

Polymers are materials widely used in biomedical science because of their biocompatibility, and good mechanical properties (which, in some cases, are similar to those of human tissues); however, these materials are, in general, chemically and biologically inert. Surface characteristics, such as topography (at the macro-, micro, and nano-scale), surface chemistry, surface energy, charge, or wettability are interrelated properties, and they cooperatively influence the biological performance of materials when used for biomedical applications. They regulate the biological response at the implant/tissue interface (e.g., influencing the cell adhesion, cell orientation, cell motility, etc.). Several surface processing techniques have been explored to modulate these properties for biomedical applications. Despite their potentials, these methods have limitations that prevent their applicability. In this regard, laser-based methods, in particular laser surface texturing (LST), can be an interesting alternative. Different works have showed the potentiality of this technique to control the surface properties of biomedical polymers and enhance their biological performance; however, more research is needed to obtain the desired biological response. This work provides a general overview of the basics and applications of LST for the surface modification of polymers currently used in the clinical practice (e.g., PEEK, UHMWPE, PP, etc.). The modification of roughness, wettability, and their impact on the biological response is addressed to offer new insights on the surface modification of biomedical polymers.

“…Typically, laser processing of polymers is performed using excimer lasers: 157-355 nm [2], 248 nm [3], 308 nm [4]; solid-state lasers with fundamental or harmonics generation: 395/790 nm [5], 532/1,064 nm [6], 1,064 nm [6,7]; and CO 2 lasers 10.6 μm [4,[8][9][10][11][12]. In terms of the laser pulse duration, both ultra-short (femtosecond [13], and picosecond [14]), as well as long (microsecond) or continuous operation lasers [8][9][10][11][12] can be utilized.…”

“…There are many scientific articles presenting laser processing of various neat polymers (without fillers): for example polytetrafluoroethylene [8,14], polyethylene [5,9,10], polycarbonate [3,[9][10][11], PMMA [3,7,10,11], polyetheretherketone [3,14], as well as fiber-reinforced polymers [12,17], but there is still a lack of information on nylon grooving properties through vaporization by infrared lasers.…”

The popular polycaprolactam (polyamide PA6), commonly referred to as nylon 6, widely used as a construction plastic, is not a typical material for micromachining by CO 2 laser vaporization. In this paper, we describe investigations of the pulsed CO 2 laser grooving of both the chemically pure and the organobentonite clay modified nylon 6. Our results indicate that doping of nylon 6 with nanoparticles of organophilized bentonite significantly improves the grooving ability, predictability of the process, and its quality. In order to determine the nature of the changes in the depth and width of the grooves as a function of the laser process parameters, theoretical modeling of the laser grooving of nylon was carried out. The basic parameters of the laser grooving process versus laser beam intensity, pulse repetition rate, scanning speed of the material and various compositions of the organophilized bentonite dopant are presented. Additionally, an example of a three-dimensional engraving/milling of tested materials as well as the impact of doping on the channel profile are examined. The modification of nylon 6 by appropriate doping with bentonite clay radically improves the quality of micromachining with a CO 2 laser.
