SECTION II. Preparation and Characterization of PBS/Carbon
Nanofiber Nanocomposite Foams
1. Introduction
Polymeric foams are the lightweight materials containing gaseous
voids by means of physical and chemical blowing agents, which have
been mainly used in the insulation, absorbents, cushion, packaging
and weight-bearing structures. [1] For the polymer nanocomposite
foams, the integration of the small amounts of nano-sized fillers into
the virgin polymer may provide enhanced thermal stability and
mechanical properties compared to those of the neat polymer foam,
and can effectively induce the nucleation of a large amount of bubbles
according to the geometry of the added-nanoparticles. [2]
In order to reduce the environmental problems caused by the non-
degradable plastics, the development of the biodegradable polymers
with the properties enough to compare with those of the commodity
plastics greatly have been required and steadily studied by extensive
research groups. Poly(butylene succinate) (PBS), one of the most
applied biodegradable plastics to the scientific and industrial fields, is a
