Surface modification of silica nanoparticles with hydrophilic polymers

“…For the grafted nanoparticles such as SiO 2 -g-POEM and SiO 2 -g-PSSA, the second weight loss was additionally observed at around 200-250 8C due to the degradation of polymeric chains [30]. The first weight loss of SiO 2 -g-PSSA nanoparticles up to 200 8C was much larger than that of SiO 2 -g-POEM nanoparticles, indicating a large amount of water sorption in an ionic polymer [36]. The weight losses from 200 to 700 8C were about 5 and 8 wt% for SiO 2 -g-POEM and SiO 2 -g-PSSA nanoparticles, respectively.…”

“…When a hydrophilic polymer such as POEM or PSSA is grafted from the surface of nanoparticles, mutual exclusion and steric hindrance effect would be effective. Thus, the surface free energy of nanoparticles can be reduced and the agglomeration can be controlled [36,43]. Therefore, the nanoparticles modified with the hydrophilic polymeric chains possess better dispersion properties compared to the neat, unmodified nanoparticles.…”

Isocyanate-modified Nano-SiO2 and Corresponding Process Optimization

“…Consequently, nanoparticles that are dispersive and polymer-compatible with a uniform particle size distribution is an active area of research-especially in processing the surface hydroxyl groups (-OH) [7][8]. There are currently many nano-SiO 2 surface modification processes, but each process has its own disadvantages [9][10][11][12]. For example, while the modification method utilizing silane coupling is easy to use, the related large-scale production is discouraged due to the expensive price of the silane-coupling agent.…”

Surface modification of nano-TiN by using silane coupling agent

“…6a, the thermal decomposition of pristine nano-TiN begins at about 180 • C and the continuous mass loss can be observed from 180 • C to 580 • C. This is likely to be due to a series of chemical reactions happening on the surface of the nano-TiN between surface groups or some physically and chemically adsorbed substances, followed by the desorption of H 2 O, etc. [1,12]. So, the mass loss of pristine nano-TiN is 1.38 %.…”

“…However, inorganic nano-particles are very prone to agglomerate in media and show poor dispersion capacity in organic solvents and oil due to their high surface energy. Because of the inconsistent interfacial interaction, the combination of the inorganic nano-particles with the polymer matrix is weak, which limits the wide application of nano-particles [1][2][3]. How to disperse the inorganic nano-particles in organic polymer matrices and improve their interfacial interaction are the main issues to be solved.…”
