摘要

LB films of giant amphiphiles composed of poly(ethylene oxide) (PEO) and polyhedral oligomeric silsesquioxanes (POSS) derivatives present fractal growth patterns. POSS modification

PEO chain length

molecular topology

and surface pressure affect the fractal growth patterns.

Abstract

Fractal structures have attracted considerable scientific interest

and fractal geometry is an effective tool to study the complicated structure and dynamic processes

such as dilation symmetry of disorder structure

percolation

gelation

and metal-insulator transition. Here

we summarized our findings of fractal growth of giant amphiphiles in Langmuir-Blodgett (LB) film. Giant amphiphiles composed of polyhedral oligomeric silsesquioxanes (POSS) derivatives and poly(ethylene oxide) (PEO)

with structural diversities of POSS head modification

POSS head number

PEO chain length

are precisely synthesized. The effect of molecular structures and operation parameters on the fractal growth patterns are discussed

in addition

other fractal growth patterns in LB films and in Langmuir films are included

aiming to understand the basic molecular principle of fractal growth in LB system.
