Effect of metal oxide fillers in urethane dimethacrylate polymer with glycerol obtained by photopolymerization synthesis
(2020-10-01)
Urethane dimethacrylate (UDMA) is a monomer widely used in photopolymerization reactions to produce biomaterials, due to its advantageous properties such as mechanical resistance and relatively low viscosity. However, this ...
A deep investigation into the thermal degradation of urethane dimethacrylate polymer
(2021-01-01)
This work investigates in depth the thermal degradation process of a polymer of urethane dimethacrylate (UDMA). UDMA monomer has been widely used in dental restorations and biomaterials. The use of density functional theory ...
Use of curcumin and glycerol as an effective photoinitiating system in the polymerization of urethane dimethacrylate
(2017-06-01)
The objectives of this study were to verify the viability of the photoinitiating system using curcumin as a photoinitiator and glycerol as a coinitiator, to analyze the thermal and morphological features of the polymers ...
Degree of conversion of polymer-matrix composite assessed by FTIR analysis
(2013-01-01)
Aims and objectives: The behavior of polymer-matrix composite is dependent on the degree of conversion. The aim of this study was to evaluate the degree of conversion of two resin cements following storage at 37°C immediately, ...

Desenvolvimento de novas aplicações para o glicerol, visando obtenção de materiais de interesse tecnológico
(Universidade Estadual Paulista (Unesp), 2018-02-23)
A síntese de polímeros a partir de resíduos industriais e biomassa é o foco de muitas pesquisas realizadas atualmente, as quais buscam a sustentabilidade, viabilidade econômica e a preservação ambiental. Desta forma, um ...
Microtensile bond strength between a UDMA fiber post and different resin cements: Effect of pre-surface treatment
(Japanese Soc Dental Materials Devices, 2016-12-01)
During a fiber post cementation, bonding failure often occurs at the junction between the fiber-post and resin-cement. Because this failure requires better characterization, we evaluated if different post surface treatment ...
