Siloxane modification of polycarbonate for superior flow and impact toughness

EVA reactive blending with Si–H terminated polysiloxane by carbonyl hydrosilylation reaction: From compatibilised blends to crosslinking networks

“…Our results produced the same observations and conclusions derived by Zhou and Osby [9]. In their work, they reported that the dispersion of a non-reactive siloxane in PC exhibited large domains with a length scale of 15e20 mm.…”

“…Moreover, the PMHS domain sizes suggested the presence of free siloxane materials in the blend. Zhou and Osby [9] reported that the presence of free siloxane in reactive PC/PDMS blends may be phase separated as a different domain from the PC matrix and the copolymer PCe PDMS. The free siloxane can migrate and coalesce with time, leading to higher than expected droplets.…”

“…Macosko et al [7] worked on the reactive compatibilisation of PDMS with polyamide 6 (PA6) and polystyrene (PS), involving PDMS with modified epoxy or anhydride end-groups. Zhou and Osby [9] also demonstrated the formation of polycarbonate (PC)/ PDMS compatibilised blends through the use of hydroxylterminated PDMS (PDMS-OH).…”

Polycarbonate/TiO2 nanofibers nanocomposite: Preparation and properties

“…Another possible reaction between AMS and polycarbonate molecules is the transesterification of polycarbonate bonds caused by hydroxyl groups (‐OH), which may arise due to hydrolysis of silane groups of AMS molecules. However, the resultant bond would be Si‐O‐C that has a characteristic infrared peak at 1,043 cm − 1 , but it was not identified on FTIR spectra from samples with AMS.…”

Assay of bacteriorhodopsin stability on polycarbonate surface by using of FTIR-ATR: a model of disk-based bioassays

“…For immobilization of BR on the polycarbonate surface, the modification should be done. So far different modifications have been done (Abenojar et al 2009;Asad Ali et al 2010;Baumann et al 2013;Carosio et al 2013;Dehaye et al 2003;Gao et al 2013;Goyal et al 2012;Heymans 1997;Iwata et al 2003;Jackeray et al 2011;Jain et al 2012;Jang et al 2014a, b;Keil et al 1998;Khan et al 2006;Kim and Masuoka 2009;Kumar et al 2003Kumar et al , 2006Kumar et al , 2012Lub et al 1988;Motaung et al 2013;Resta et al 2013;Rodríguez et al 2002;Saarikoski et al 2009;Singh et al 2007;Srivastava et al 2002;Sun et al 2003;van der Wel et al 1993;Verkuijlen et al 2014;Wang et al 2000;Zajíčková et al 2001;Zhou and Osby 2010). In the present study we try to immobilize bacteriorhodopsin on polycarbonate surface by modifying of polycarbonate functional groups in two ways.…”
