Special Issue Information

Dear Colleagues,

Since the first laser was described in 1960, one has been able to find in the literature studies on laser interaction with organic and polymer materials. Thus, several laser-based techniques have been developed, to be used as analytical tools, as is the case of matrix-assisted laser desorption ionization (MALDI) and laser-induced breakdown spectroscopy (LIBS), or as fabrication tools like pulsed laser deposition (PLD), matrix-assisted pulsed laser evaporation (MAPLE) and laser-induced forward transfer (LIFT). Other laser applications employed low fluences so that the polymer surface may be chemically or physically modified or both.

Additionally, laser-based techniques constitute attractive alternatives for the processing of polymers, affording the sought versatility and reliability. Examples are laser-induced periodic surface structuring (LIPSS), laser foaming, and other techniques based on laser ablation, as laser interference lithography (LIL). All these methods can be used to fabricate substrates with a variety of high-precision patterns at different length scales. More recently, specific laser processing techniques, taking advantage of optical trapping or of plasmonic enhancement effects, have been developed and applied to the nanopatterning of soft polymer materials. In general, laser-based techniques can be applied to many different materials in noncontact and flexible set-ups under a great variety of environments. Moreover, the processing can be tuned both to the materials properties and to the desired surface pattern by controlling the laser parameters like intensity, fluence, wavelength, pulse duration, total photon dose, and several other irradiation conditions.

This Special Issue “Laser Applications in Polymers” aims to gather contributions on recent advances about the use of laser techniques in polymer science, concerning analysis, thin film fabrication, surface and bulk modification and, micro- and nanostructuring, and considering both fundamental studies and the potential applications of the modified polymer materials.

The influence of irradiation on mechanical properties of polymer foils used in spacecraft applications has widely been studied via macroscopic tensile samples. An increase in the local resolution of this investigation can be achieved by reducing the sample’s dimensions. A femtosecond laser enables a fast fabrication of micro-samples with dimensions from tens of μ m to the mm range, with ideally no influence on the material. Tensile experiments using such micro-tensile samples were conducted on FEP, Upilex-S and PET foils. The influence of the laser processing on the polymer foils was evaluated. Additionally an investigation of degradation due to electron irradiation was performed. Furthermore an outlook to extend this technique to depth-resolved measurements by preparing samples from locally thinned foils is presented. The study demonstrates the feasibility of femtosecond laser processing for rapid fabrication of micro-samples, enabling insights into the effect of electron irradiation on local mechanical properties of polymers.
