Polymethylmethacrylate structure
WebHowever, conventional thermal-NIL that uses polymeric resin such as Poly(methyl methacrylate) has limited applicability to the fabrication of optical devices, owing to the low refractive index of the resin. As such, we developed SnO2-nanoparticle-containing imprint resin that has a high refractive index and is applicable in the thermal-NIL method. WebMay 1, 2013 · 1 Introduction. Nowadays, research to investigate organic and inorganic composite particles is of great interest, principally because such particles can demonstrate innovative and improved properties such as mechanical, chemical, electrical, rheological, optical and magnetic by independently altering the composition, dimensions and …

WebPoly (ethyl methacrylate) ( PEMA) is a hydrophobic synthetic acrylate polymer. It has properties similar to the more common PMMA, however it produces less heat during polymerization, has a lower modulus of elasticity and an overall softer texture. [7] It may be vulcanized using lead oxide as a catalyst [8] and it can be softened using ethanol.
