“…The decreasing d avg results from the reduced repulsions between GOs with adding polymers. 41,43,44 Therefore, it is not new that d avg decreases with c p in all MWs. However, it is worth noting that the d avg is decreased more with higher PEG MW at a same c p in the range of c p ≤ 10 wt.…”

“…Inclusion of polyelectrolytes can also induce substantial destabilization in colloids, where nonadsorbing polymers can induce depletion flocculation 53−55 and adsorbing polymers can induce flocculation by bridging. 53,56,57 In the latter case, particles act as cross-linkers between polymer molecules or vice versa. CS and HA contain repeat carboxylic acid moieties similar to poly(acrylic acid) and were hypothesized in this study to adsorb to the surface of the HAP particles via a similar mechanism.…”

“…Note that in the literature often the synonymous name poly­(ethylene oxide) has been used. , Grafting or adsorption of polymers is of general interest and typically influences the phase behavior, the stability of suspensions, the diffusion, and also the interaction potential. In the past, the majority of studies dealt with spherical colloids but also the rodlike fd-virus has been studied extensively. The wildtype fd-virus has a molar mass of 1.64 × 10 7 g mol –1 , a contour length ( L ) of 880 nm, a radius ( a ) of 3.4 nm, and a persistence length ( L P ) of 2.2 μm. The fd-virus consists of single-stranded DNA, coated with amino groups and acidic residues, which determine the surface properties of the fd-virus.…”
