Effect of surfactants on the porogen size in the low-k methylsilsesquioxane/polystyrene hybrid films

Magnetic-propelled Fe3O4–chitosan carriers enhancel-asparaginase catalytic activity: a promising strategy for enzyme immobilization

“…It is well known that zeta potential measurements might provide some additional insights into the magnitude of the repulsion or attraction between particles. 51 Therefore, the successful coating of chitosan was confirmed by the zeta potential analysis of the resulting composite. The zeta potential results are shown in Fig.…”

The influence of porosity on the hemocompatibility of polyhedral oligomeric silsesquioxane poly (caprolactone-urea) urethane

“…Silk Sugar (British Sugar Industrial, UK) was used to create pores around 5 um and filtered NaHCO3 was used to create pores around 40 um (Chen et al , 2012). A mixed solution of porogens of both Silk Sugar and NaHCO 3 (ratio of 1:1) was produced to try to create interconnectivity between pores.…”

The Effect of Ch₄ Plasma Treatment on Low Dielectric HSQ Films

“…At present, the lower dielectric constant of a film can be obtained by producing pores or reducing the polarity of the chemical bonds. Many studies focused on the characteristics of low dielectric constant materials [3][4][5][6][7][8][9][10][11][12]. Different kinds of low dielectric constant materials, such as methylsilsesquioxane (MSQ), HSQ, SiCOH, a porous silica, silica-carbon and fluorinatedcarbon, have been investigated in recent years.…”
