“…In this case, additives are required. These compounds can be either organic dyes (cyanine), metal complexes (copper complexes), or nano/microparticles (e.g., TiO 2 , Sb 2 O 3 , SnO 2 :Sb 2 O 3 , BiO 2 , black carbon, and graphene). Though the concentration of additives remains at a very low level (typically from 0.01 to 3.0 wt.…”

A versatile and efficient method for the permanent marking of polymer surfaces that combines inkjet deposition and near‐infrared (NIR) laser curing is investigated. The NIR laser treatment forces the ink particles to migrate into the upper layers of the polymer. This results in the fixation of a permanent grayscale image that can be applied to various polymers, such as polypropylene, which is widely used in industry but still difficult to mark. The physiochemical processes induced by laser curing are investigated by electronic and optical microscopy. The dependence of the thickness of the deposited ink and the laser power on the contrast of marking are also studied. A mechanism implying fast laser‐induced melting of the polymer surface followed by displacement of carbon nanoparticles by convection is proposed. Finally, a comparison of the aging properties of samples prepared by this process and standard UV ink is proposed to illustrate the interesting nature of this new polymer marking process. Integrating the ink under the surface of the polymer, as in a skin tattooing procedure, by laser curing is an efficient way to generate permanent images on polymer surfaces.

“…Zheng Cao et al [42] showed that 0.02% MoS 2 content and the selection of appropriate marking parameters result in obtaining graphic signs with high contrast. Wen et al [43] found that the addition of only 0.005 wt% graphene in the matrix of the material acts as an effective absorber of laser pulses in the near-infrared range. Zhou et al [44] proved that the use of carbon nanotubes affects the obtaining of high contrast between the graphic symbol and the background in the case of PP marking.…”

Modification of Laser Marking Ability and Properties of Polypropylene Using Silica Waste as a Filler

Polypropylene (PP) belongs to the group of polymers characterized by low susceptibility to absorption of electromagnetic radiation in the infrared range (λ = 1064 nm). This research consisted of assessing the possibility of using silica waste from the metallurgic industry as an additive for PP laser marking. The modifier was introduced into the polymer matrix in the range from 1 to 10 wt%. The effects of laser radiation were assessed based on colorimetric tests and microscopic surface analysis. The mechanical properties of the composites were determined during the static tensile tests. The thermal properties were investigated via differential scanning calorimetry. It was found that the introduction of silica waste into polypropylene allows for the effective marking of sample surfaces with the use of a laser beam. The greatest contrast between the graphic symbol and the background was obtained for silica contents of 3 and 5 wt%, with the use of a low-speed laser head and a strong concentration of the laser beam. The application of silica caused an increase in the modulus of elasticity and the tensile strength of the composite samples. Increases in the crystallization temperature and the degree of crystallinity of the polymer matrix were also observed. It was found that silica waste can act as multifunctional additive for polypropylene.

“…The surface of a typical laser-irradiated material shows black marking by carbonization, 10 light/white marking by foaming, and color changes by the photothermal reaction. 11 In recent years, laser marking technology has been used in the fields of metals, 12−14 ceramics, 15,16 plastics, 17−19 and wet soft materials. 20,21 Compared with the conventional printing method, laser marking is a fast and flexible process technology and more environmentally friendly, and the contrast and durability are also improved.…”

“…The laser-sensitive additives are capable of absorbing laser energy well and causing local overheating, leading to carbonization and formation of black markings. Laser marking sensitizers are mainly classified into inorganic, 18,19,23 organic, 24,25 and polymer/inorganic composite materials. 21,26,27 Wen et al 19 studied the use of graphene in the field of polymer laser patterning.…”

In this work, using ferroferric oxide (Fe3O4) and zirconium oxide (ZrO2) as laser-sensitive particles and thermoplastic polyurethane (TPU) as the matrix resin, a series of TPU/Fe3O4/ZrO2 composites were prepared by melt blending, and the effect of the laser marking additive content, composition, and laser marking parameters on the laser marking properties of composites was investigated. The laser marking mechanism of Fe3O4/ZrO2 additives and the role of each component in TPU laser marking were studied by metallographic microscopy, color difference test, scanning electron microscopy, and Raman spectroscopy. Fe3O4 nanoparticles as a laser sensitizer component, on the one hand, can act as a pigment to make the TPU substrate black and, on the other hand, can absorb laser energy to contribute to the formation of laser markings on TPU composite surfaces. In addition, the introduction of ZrO2 nanoparticles can help absorb the laser energy, while the contrast can be improved to enhance the laser marking performance of the TPU composite. Through thermogravimetric analysis, the changes in the thermally stable properties of TPU composites before and after laser marking were investigated, and the results indicated that Fe3O4/ZrO2 nanoparticles can absorb the laser energy, causing melting and pyrolysis of the TPU backbone at a high temperature, to produce a gaseous product resulting in foaming. Finally, the high-contrast and light-colored markings were formed on the black TPU composite surface. This work provides a facile method for producing high-contrast and light-colored markings on the dark TPU composite surface.
