Poly(butylene succinate)-Based Biocomposites Filled with Polysaccharide Nanocrystals: Structure and Properties
In this work, two polysaccharide nanocrystals-rod-like cellulose whisker (CW) and platelet-like starch nanocrystal (SN) were individually incorporated into an aliphatic thermoplastic polyester to produce biodegradable poly(butylene succinate) (PBS)/nanocrystals biocomposites. At loading levels of 2 wt% CW or 5 wt% SN the PBS-based nanocomposites showed simultaneous&...

Surface Acetylation of Cellulose Nanocrystal and Its Reinforcing Function for Poly(lactic acid)
A novel and facile method for surface acetylation of cellulose nanocrystals (CN) was developed by reaction with acetic anhydride and hydroxyl groups on the surface of CN. The resultant acetylated cellulose nanocrystals (ACN) exhibited improved dispersion in various organic solvents and reduced polarity as compared with unmodified CN. These ACN were subsequently introduced into a p...

SINGLE-CHAIN CONFORMATION FOR INTERACTING POLY(N-ISOPROPY ACRYLAMIDE) IN AQUEOUS SOLUTION
The demixing phase behavior of Poly(N-isopropylacrylamide) (PNIPAM) aqueous solution is investigated using smallangle
neutron scattering. This polymer phase separates upon heating and demixes around 32 °C. The pre-transition temperature
range is characterized by two scattering modes; a low-Q (large-scale) signal and a high-Q dissolved chains signal. In order to get
insight into this pr...

Detecting Surface Hydration of Poly(2-hydroxyethyl methacrylate) in Solution in situ
Understanding the interfacial molecular structures of anti-fouling polymers in solutions is extremely important in research and applications related to chemistry, biology, and medicine. However, it is generally challenging to probe such buried solid/liquid interfaces in situ. We herein report a molecular-level study on detecting the interfacial molecular s...

Effects of Ethyl Cellulose on the Crystallization and Mechanical Properties of Poly(β-hydroxybutyrate)
International Journal of Biological Macromolecules, 2016,88C, 120-129.
ABSTRACT:
Ethyl
cellulose (EC) was blended with poly(β-hydroxybutyrate)
(PHB), aiming at controlling crystallization and mechanical properties of PHB. The obtained PHB/EC blend is an immiscible system,
and the discrete EC phase behaves dual characteristics in the PHB matrix, as
the viscoelastic droplets dur...

Conformational Identification and Phase Transition Behavior of Poly(trimethylene 2,6-naphthalate) α?Form Modification
Poly(trimethylene 2,6-naphthalate) (PTN) is one of the 1,3-propanediol (PDO)-based aromatic polyesters which has potential applications for special barrier films and
packaging due to its excellent oxygen and carbon dioxide gas barrier property. In this work, we investigated the chain conformation and phase transition behavior of poly-
(trimethylene 2,6-naphthalene) (PTN) α-form crystal with synch...

Methylsulfonylmethane-loaded electrospun poly(lactide-coglycolide) mats for cartilage tissue engineering
Abstract Methylsulfonylmethane (MSM) is popularly used for the therapy of arthritic and rheumatic diseases but seldom in tissue engineering applications for cartilage regeneration. In this study, biodegradable poly(lactide-co-glycolide) (PLGA) fibrous mats containing MSM with different doping levels were fabricated by electrospinning. The MSM-loaded mats were interc...

A facile preparation of poly(ethylene oxide)-modified medicalpolyurethane to improve hemocompatibility
tPoly(ethylene oxide) (PEO) has been widely applied in the modification of biomaterials because itshows high hydrophilicity and excellent biocompatibility. In the current study, the surface of medi-cal polyurethane (PU) films was modified to improve hydrophilicity and hemocompatibility by a facilemethod without catalyst. PU films were modified directly using poly(ethylene oxide) (PEO) with various...

Fractal Structures of the Hydrogels Formed in Situ from Poly(N-isopropylacrylamide) Microgel Dispersions
Dispersions of poly(N-isopropylacrylamide) (PNIPAM) microgel thermally gel in the presence of inorganic salts. The in situ-formed hydrogels, with a network of soft
particles, represent a new type of colloidal gels. Here, their fractal structures were determined by rheological measurements, using the models of both Shi...
