“…After blending HMTAF with photoinitiators: camphoquinone and ethyl 4-(dimethylamino)benzoate (EDMAB), and curing with a halogen lamp (blue light), conversion of monomer HMTAF into polymer was indicated by significant decrease of intensity of characteristic peak of carbon-carbon double bond at 1537 cm −1 in IR spectra as shown in Figure 4 [24]. As a result, monomer HMTAF is able to polymerize under the blue light which is used in dental clinics.…”

Hydrolytic and enzymatic degradation of resin adhesives over time has been mainly attributed to secondary caries formation of methacrylate-based tooth-colored resin-based composite restorations. Ability of resin adhesive monomers to infiltrate into demineralized dentin forming stiff polymer matrix and potentially bonding to tooth structure is also a crucial property. The only commercially available antibacterial monomer, 12-methacryloyloxydodecyl pyridinium bromide (MDPB), is a quaternary ammonium methacrylate. This methacrylate monomer undergoes hydrolytic degradation, and could not bond to tooth structure. In this study, a new hydrolytic resistant monomer HMTAF was synthesized. It is methacrylamide-based monomer that, unlike methacrylate, is highly resistant to hydrolysis. Its molecular structure has particular functional groups; quaternary ammonium fluoride salt with potential antibacterial fluoride-releasing activity, hydroxyl and amide group with hydrogen bonding potential to dentin collagen. Hydroxyl group also increases monomer hydrophilicity for better penetration into water-saturated dentin and sufficient resin-dentin bond. The synthesized HMTAF and its polymer showed no hydrolytic degradation in acidic environment, while MDPB and its polymer were partially decomposed under this challenge. The conversion of monomer HMTAF to polymer was illustrated by FT-IR. The results indicated that HMTAF is highly resistant to hydrolysis, polymerizable and non-cytotoxic to Vero cell lines. It is a potential monomer to be incorporated into resin adhesives for improving hydrolytic and enzymatic resistance.

“…4.6 V. This result shows that P(MCA-GM400)-based gel polymer electrolytes is electrochemically stable up to ca. 4.6 V. The oxidation potential of the solid polymer electrolytes with PMCA matrix was about 3.1 V [19]. PC in the P(MCA-GM400) gel electrolytes will protect the decomposition of PMCA matrix.…”

“…5 Various polymer matrices, including polyacrylonitrile, polyethyleneoxide (PEO), poly(vinyl alcohol), polyvinylchloride, polymethylmethacrylate, polyvinylidene fluoride (PVDF), poly(methacrylamide), polytetrafluoroethylene and so on, have been studied for their suitability for the polymer electrolytes or ion-conducting membranes. 3,6 –9 Although PEO-based polymer electrolytes are the earliest studied polymer electrolyte systems, 10,11 poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) has appeared to be one of the most promising polymer matrix as a host for the electrolyte system due its high dielectric constant ( ∊ = 8.4), 5 low glass transition temperature ( T g ) around −65°C and the presence of strong electron withdrawing group (–C–F) that helps in greater dissociation of lithium salts 12 –15 and thereby provide high mobile ions concentration. In addition, with the increase in fluorine atoms by co-polymerising HFP in the Li ion conducting polymer electrolyte system, high Li ion transference number (approximately 0.4 for lithium triflate (LiCF 3 SO 3 )) can be achieved.…”

Polymer electrolytes consisting of poly(vinylidene fluoride-co-hexafluoropropylene) in combination with lithium triflate (LiCF3SO3) salt of varying concentration have been prepared using the conventional solution casting technique in the argon atmosphere. Structural electrical characterizations of the synthesized electrolytes have been performed using various imaging and spectroscopic techniques. The DC conductivities determined by complex impedance plots reveal gradual increase with increase in salt concentration up to a particular limit and decrease subsequently. The maximum DC conductivity obtained at 300 K is 1.64 × 10−4 Scm−1 for the electrolyte with a polymer to salt weight ratio of 1:1.8. The temperature-dependent conductivity followed a mixed Arrhenius and Vogel–Tamman–Fulcher type behaviour for the polymer electrolytes. From the Summerfield master curve plot, the conductivity of the solid polymer electrolytes is found to depend not only on ion dynamics but also on the segmental mobility of the polymer chains.
