Special Issue Information

Dear Colleagues,

Continued innovations in the polymer industry have made polymer surface modification methods a subject of intense research. These physical surface modification methods include flame, plasma discharge, microwaves, UV, gamma-ray, electron beam, ion beam, plasma, and laser treatments. This Special Issue of Materials titled “Advances in Polymer Surface Modification” is devoted to the principles of operation of aforementioned methods, their advantages and disadvantages, polymer surface characterization, experimental techniques developed for the characterization of polymer surfaces, physical chemistry of polymer surfaces, novel techniques for polymer surface modification, bio-mimetic and self-healing polymer interfaces, ecological aspects of polymer surface modification and related themes. Submission of research and review papers is encouraged.

Calcium carbonate (CaCO3) is a widely used inorganic powder, but its industrial applications are limited by its hydrophilicity and oleophobicity. Surface modification of CaCO3 can improve its dispersion and stability in organic materials and further improve its potential value. In this study, CaCO3 particles were modified with silane coupling agent (KH550) and titanate coupling agent (HY311) combined with ultrasonication. The oil absorption value (OAV), activation degree (AG), and sedimentation volume (SV) were employed to evaluate the modification performance. The results showed that the modification effect of HY311 on CaCO3 was better than that of KH550, and ultrasonic treatment played an auxiliary role. Based on response surface analysis, the optimal modification conditions were determined as follows: the HY311 dosage was 0.7%, the KH550 dosage was 0.7%, and ultrasonic time was 10 min. The OAV, AG, and SV of modified CaCO3 under these conditions were 16.65 g DOP/100 g, 99.27%, and 0.65 mL/g, respectively. The SEM, FTIR, XRD and thermal gravimetric analyses indicated successful coating of HY311 and KH550 coupling agents on the surface of CaCO3. The optimization of the dosages of two coupling agents and ultrasonic time improved the modification performance significantly. Full article

This study investigates the treatment of surfaces with jet plasma at atmospheric pressure in the presence of acrylic acid as a resource-saving and efficient approach to joining polymers on polystyrene (PS) and polyamide 12 (PA 12) surfaces. Acrylic acid was added in order to introduce functional groups to the polymer surfaces. XPS analysis revealed a high density of oxygen-containing groups, e.g., carboxylic acid groups, on the polymer surfaces, the detailed composition depending on the polymer. The AFM measurements indicated that the modification of polyamide resulted in morphological changes and an increase in surface roughness due to polymer recrystallization. When the surface-modified polymers were brought in contact under a load, significant adhesion between the polymer surfaces was measured. In particular, PS and PA 12, which are otherwise difficult to join by gluing, could readily be connected in this way. The joint polymers could be separated intentionally by immersion in water, thus enabling the recycling of the materials. The resistance of the joint to water depends on the polymer system, with polyamide providing strikingly higher resistance than polystyrene. Accordingly, treating the joint polymers with water allows debonding on demand, particularly when PS is involved. Exposure of modified polymer surfaces to solutions of metal ions increased the resistance of joint polymers to water. Full article
