Effect of Hydrothermal Aging on Injection Molded Short Jute Fiber Reinforced Poly(Lactic Acid) (PLA) Composites
This work focused on the durability of short jute fiber reinforced poly(lactic acid) (PLA) composites in distilled water at different temperatures (23, 37.8 and 60 A degrees C). Morphological, thermal and mechanical properties (tensile, flexural, and impact) of jute/PLA composites were investigated before and after aging. Different from traditional synthetic fiber reinforced polymer composites, th...

Water absorption and hygrothermal aging behavior of short ramie fiber-reinforced poly(lactic acid) composites
Short ramie/poly(lactic acid) (PLA) composites were prepared by using extrusion and injection moulding method. The water absorption and hygrothermal aging behaviors of ramie/PLA composites at 60 degrees C was analyzed. The water absorption and mechanical properties of the ramie/PLA composites with immersion time were reported and compared to those of neat PLA. Crystallinity and molecular weight of...

2018-Macromol Mater Eng: Nanoclay Reinforced Self-crosslinking Poly(N-hydroxyethyl acrylate) Hydrogels with Integrated High Performances
Despite recent significant progress in fabricating tough hydrogels, it is still a challenge to realize high strength, large stretchability, high toughness, rapid recoverability and good self-healing simultaneous in a single hydrogel. Herein, Laponite reinforced self-crosslinking poly(N-hydroxyethyl acrylamide) (PHEAA) hydrogels (i.e. PHEAA/Laponite NC gels) with dual&nbs...

(Macromol. Rapid Commun)LCST-Type Hyperbranched Poly(oligo(ethylene glycol) with Thermo- and CO2-Responsive Backbone
A novel hyperbranched lower critical solution temperature (LCST) polymer with sharp temperature and CO2-responsive behaviors is presented in this study. The target polymer of hyperbranched poly(oligo(ethylene glycol) (HBPOEG) is constructed using POEG as the backbone and tertiary amines as branch points. Phase transition of HBPOEG in aqueous solution is investigated by heating and cooling the sy...

017. Multiscale modeling of glass transition in polymeric films: Application to stereoregular poly(methyl methacrylate)s
The multiscale modeling scheme has been extended to derive the coarse-grained potentials for simulating glass transition temperatures (Tg) of the bulks and the freely-standing films of two stereoregular poly (methyl methacrylate) (PMMA) configurations. The extensive molecular dynamics simulations reasonably reproduce the volumetric properties. Furthermore, the “dynamical Tg” sensibly exhibits ...

[J. Polym. Sci., Part A: Polym. Chem.] Thermoresponsive polymeric nanoparticles based on poly(2‐oxazoline)s and tannic acid
Hydrogen bonding is widely present and plays a significant role in material science and supramolecular chemistry. This work reports a straightforward strategy for the preparation
of polymeric nanoparticles from neutral poly(2-oxazoline)s (POx) and tannic acid (TA) driven by their intermolecular hydrogen bonding. Dynamic light scattering (DLS) and scanning electron microscope (SEM) measurement...

A Kind of Cotton-like Micro- and Nano- Poly (lactic acid) Nonwoven Fiber Fabricated by Centrifugal Melt-spinning for Tissue Engineering.
Biodegradable materials in the form of nonwoven fibers have attracted increasing attention for tissue engineering applications because they offer large surface areas and interconnected networks. In this study, cotton-like nonwoven poly(lactic acid) (PLA) fibers were successfully fabricated by centrifugal melt-spinning. The effects of centrifugal speed and secondary melt-spinning processing on t...

Green Poly(β-hydroxybutyrate)/Starch Nanocrystal Composites: Tuning the Nucleation and Spherulite Morphology through Surface Acetylation of Starch Nanocrystal
Carbohydrate Polymers, 2018, 195C, 79-88.
ABSTRACT:
Starch nanocrystal (SNC) particles were used as the filler to prepare green composites with biodegradable poly(β-hydroxybutyrate) (PHB). An interesting way to tune the nucleation and banded morphology of composites by the surface acetylation of SNC was proposed. Pristine SNC acts as the nucleating agent, while acetylated...

Crystallization of Green Poly(ε-caprolactone) Nanocomposites with Starch Nanocrystal: The Nucleation Role Switching of Starch Nanocrystal with Its Surface Acetylation
Industrial & Engineering Chemistry Research, 2018, 57(18), 6257-6264.
ABSTRACT:
Poly(ε-caprolactone) (PCL) was filled with very small amount of starch nanocrystals (SNC), with the objective to control its crystallization. Three kinds of SNC particles, including the pristine one and the acetylated ones with low-level and middle-level substitutions, were used. Their roles acted d...
