摘要

The reduced first cumulant [

which differs from previously reported behavior of individual chain systems with low polydispersity feature.

Abstract

This work reports the structural feature and internal motion of one novel hyperbranching cluster system in dilution solution. The cluster system is composed of HB-PS

300

-P

hypergraft copolymer chains with uniform subchain

high molar mass and low polydispersity (

=1.73×10

g/mol and

≈1.07)

where HB-PS and P

BA represent hyperbranched polystyrene core and poly(

tert

-butyl polyacrylate) graft

respectively. In the selective solvent of PS blocks (cyclohexane

=34.5 °C)

the aggregation kinetics and structural feature are found to be precisely tunable for assembled clusters by the aggregation temperature (11 °C

17 °C) and time (0 h

24 h). An interesting structural evolution kinetics is observed

namely

the fractal dimension (

) of clusters is found to first increases and then decreases with

eventually

it reaches a plateau value of

≈3.0

corresponds to a uniform spherical structure. By using dynamic light scattering (DLS) to monitor the number and strength of relaxation modes in

(

) with

being the decay rate and

being the scattering vector

it is quantitatively revealed that the relaxation

intensity contribution and mode origin of internal motions of clusters are neither similar with previously reported cluster systems with high polydispersity

nor with the classical linear chain systems. In particular

in the broad range of 2.0

6.0

we have observed that the reduced first cumulant [

* =

(

)/(

)] does not display an asymptotic behavior. Whereas

a better asymptotic behavior is observed by plotting

(

versus

. For the first time

our observation provides direct evidence supporting that

for hyperbranching cluster system with low polydispersity and high local chain segment density

the hydrodynamic interaction is greatly weakened due to the enhanced hydrodynamic shielding effect.
