“…Furthermore, the advantage of these materials is the possibility of their regeneration in the halogenation process, thanks to which they can be used many times [ 33 ]. Few previous works were devoted to polymeric materials based on polystyrene derivatives chemically modified with hydantoins, which were then chlorinated [ 34 , 35 , 36 , 37 ].…”

“…Similarly in other works—various types of the polymers were successfully modified with N -halamines, but the reactive sites were consumed in reaction [ 44 , 45 , 46 , 47 ]. The biocidal activity of N -halamine materials are strongly associated with the total halogen content because the mechanism of the microorganisms inactivation is based on direct transfer of the oxidative halogen from material to the cell [ 29 , 36 ].…”

Current demand for new protective materials ensuring sterility is systematically growing. The purpose of this work was the synthesis of the biocidal N-halamine hydantoin-containing chitosan (CS-CMH-Cl) and characterization of its properties. The functionalization of the chitosan by 5-hydantoinacetic acid substitution leads to obtaining the CS-CMH polymer, which was chlorinated in next step to transform N-H into N-Cl bonds. In this study, the possibility of forming two biocidal N-Cl bonds in hydantoin ring, grafted onto chitosan chains, was proved. The structure and stability of the prepared material was confirmed by spectroscopic (FTIR, NMR, colorimetric test) and microscopic analyses (SEM, AFM). Surface properties were investigated based on contact-angle measurements. In addition, the thermal and photochemical stability of the obtained samples were determined as functional features, determining the range of potential use. It was found that both modified chitosan polymers (CS-CMH and CS-CMH-Cl) were characterized by the smaller thermal stability and more hydrophilic and rougher surface than unmodified CS. Photooxidative degradation of the obtained materials was observed mainly on the sample surface. After irradiation, the surfaces became more hydrophilic—especially in the case of the CS-CMH-Cl—which is advantageous from the point of view of the antibacterial properties. Antibacterial tests against S. aureus and E. coli confirmed the antibacterial activities of received CS-CMH-Cl material.

“…Współczesne trendy naukowe obejmują również grupę polimerów o właściwościach biocydowych, które mogą być wykorzystane tam gdzie jest wymagana duża sterylność (filtry do wody pitnej, urządzenia medyczne, wyposażenie szpitali) [89][90][91][92][93][94]. Przykładem takich materiałów mogą być pochodne polistyrenu z ugrupowaniami Nhalaminowymi.…”

“…Przykładem takich materiałów mogą być pochodne polistyrenu z ugrupowaniami Nhalaminowymi. Są one mniej odporne termicznie od polimerów niemodyfikowanych ze względu na niestabilność wiązania NCl obecnego we wprowadzonych podstawnikach [90,91].…”

Przedstawiono bieżące kierunki badań stabilności termicznej polimerów, ze szczególnym uwzględnieniem nowatorskich układów polimerowych: kompozytów i nanokompozytów, polimerów biodegradowalnych, biocydowych i do zastosowań specjalnych. Opisano ogólny mechanizm degradacji termicznej zachodzącej podczas przetwórstwa i podstawowe aspekty kinetyczne tego procesu. Omówiono przykłady badań właściwości termicznych wybranych tworzyw na bazie poliuretanów, żywic epoksydowych, kopolimerów kwasu akrylowego i poliestrów.

“…Research is being conducted on a number of biocidal substances that potentially can be introduced into polymers. For example, direct contact of N-halamine acts as a biocidal on E. coli and Staphylococcus aureus [9]. Polyhexamethyleneguanidine (PHMG) is a biocidal, cationic polymer based guanidine salt, synthesized from hexamethylenediamine and guanidine HCl [10].…”

Experiments were conducted to investigate the antifungal activities of polyhexamethyleneguanidine (PHMG) derivatives introduced into polylactide (PLA), polyhydroxybutyrate (PHB) and polycaprolactone (PCL) against Aspergillus niger, Penicillium chrysogenum and Candida albicans. All of the PHMG derivatives inhibited the germination of A. niger and P. chrysogenum. All of the derivatives exerted a much stronger inhibitory effect on the cells of C. albicans. PHMG granular polyethylene wax (at the concentration of 1.0%) has a fungicidal effect. The reduction in the number of yeast cells capable of growing on the surface composites PLA, PHB and PCL with PHMG granular polyethylene wax for 24 h was R > 2. PHMG derivatives introduced into PLA decreased hydrolases activity in A. niger and P. chrysogenum. All of the PHMG derivatives introduced into all investigated polymers inhibited the hydrolases activity in C. albicans proportionately to concentration. PHMG granular polyethylene wax at a concentration of 1.0% most strongly inhibited hydrolases activity in yeast. The composites produced from PLA, PHB, PCL and this PHMG derivatives can be used in many areas to reduce the growth of yeast. The studied composites can potentially be used for the production of biomedical or packaging materials.
