“…Plasticizers are additives that function by embedding themselves in-between polymer chains, making them apart, reduce bonding between chains, and increased free volume and some swelling. These improve flexibility and durability of materials [16] [17] [28]. In our study, we incorporate ILs into tissue conditioner in order to achieve both antifungal activity and function as plasticizer.…”

Denture stomatitis and fungal infection are commonly found in long-time denture wearer. Ionic liquids have been used as plasticizer and also possess antimicrobial activity. In this study, ionic liquid in form of 1-Decyl-3-methylimidazolium chloride was incorporated into tissue conditioner (GC Soft-liner TM ) to improve antifungal activity. Physical and mechanical properties were evaluated. Compliance was carried out using penetration test according to ISO 10139-1. Weight change, water absorption and solubility were determined by weight measurement. Conventional and nystatin-incorporated tissue conditioner served as controls. Results showed that ionic liquid-incorporated tissue conditioner significantly decreased fungal formation, both in material suspension and on material surface. The penetration depth of all groups tended to reduce over time with no significant difference at each time point. After water immersion, ionic liquid-and nystatin-incorporated tissue conditioner gained weight while conventional group showed weight loss. The percentage of water absorption of conventional group was significantly lower than ionic liquid and nystatin group, while the percentage of water solubility of nystatin group was significantly higher than others. Our work indicated that antifungal ionic liquid-incorporated tissue conditioner met the standard criteria in terms of material compliance. However, further studies including dynamic viscoelastic property are needed before clinical trial or application.

“…[4][5][6][7][8][9][10][11][12] A plasticizer weakens the intermolecular topological interaction between neighbor polymer chains, leading to low viscosity in the flow region. Furthermore, the glass-to-rubber transition occurs at low temperature because the relaxation time of the segmental motion is shortened.…”

“…28 Imidazolium ionic liquids have been proposed as performant plasticizers for PVC, 29 and especially for PMMA. [30][31][32][33] In this paper, it is shown that highly luminescent flexible films can be obtained by doping europium(III) complexes into a composite material consisting of PMMA and the ionic liquid 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)-imide, [C 6 mim][Tf 2 N], as the plasticizer. Different europium(III) compounds, both ionic and non-ionic complexes, have been selected: [Eu(tta) 3 3 ], where tta is 2-thenoyltrifluoroacetonate, phen is 1,10-phenanthroline, nta is 2-naphthoyltrifluoroacetonate, dpa is 2,6-pyridinedicarboxylate (dipicolinate) and choline is the 2-hydroxyethyltrimethyl ammonium cation (Fig.…”

Flexible luminescent polymer films were obtained by doping europium(III) complexes in blends of poly(methyl methacrylate) (PMMA) and the ionic liquid 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide, [C 6 3 ], where nta is 2-naphthoyltrifluoroacetonate, tta is 2-thenoyltrifluoroacetonate, phen is 1,10-phenanthroline, dpa is 2,6-pyridinedicarboxylate (dipicolinate) and choline is the 2-hydroxyethyltrimethyl ammonium cation. Bright red photoluminescence was observed for all the films upon irradiation with ultraviolet radiation. The luminescent films have been investigated by high-resolution steady-state luminescence spectroscopy and by time-resolved measurements. The polymer films doped with b-diketonate complexes are characterized by a very intense 5 D 0 -7 F 2 transition (up to 15 times more intense than the 5 D 0 -7 F 1 ) transition, whereas a marked feature of the PMMA films doped with [choline] 3 [Eu(dpa) 3 ] is the long lifetime of the 5 D 0 excited state (1.8 ms).
