Influence of poly(butylenes adipate-co-terephthalate) on the properties of the biodegradable composites based on ramie/poly(lactic acid)
Ramie/poly(lactic
acid) (PLA) composites were prepared by using two-roll mill. Poly(butylenes adipate-co-terephthalate)
was added into the composites, and the effect of PBAT on the mechanical
properties and thermal properties of the composites was investigate. The tensile
and flexural strength decreased with the increase of PBAT content, and the
addition of a small amount of PBAT increased the imp...

Study on short ramie fiber/poly(lactic acid) composites compatibilized by maleic anhydride
Short ramie fiber reinforced poly(lactic acid)(PLA) composites without
and with maleic anhydride(MA) were developed. The influence of PLA-g-MA as a compatibilizer on the
properties of the composites was studied. The tensile, flexural and impact
strength of the composites have improvements with the addition of PLA-g-MA. The morphology of fracture surface
evaluated by SEM indicates that the compos...

Preparation and characterization of biodegradable poly(lactic acid)-block-poly(ε-caprolactone) multiblock copolymer
Biodegradable copolymers of poly(lactic acid)-block-poly(e-caprolactone) (PLA-b-PCL) were successfully prepared by two steps. In the first step, lactic acid monomer is oligomerized to low molecular weight prepolymer and copolymerized with the (e-caprolactone) diol to prepolymer, and then the molecular weight is raised by joining
prepolymer chains together using 1,6-hexamethylene diisocyanate (HDI)...

Flame-retardancy and anti-dripping effects of intumescent flame retardant incorporating montmorillonite on poly(lactic acid)
In the present study, the effects of intumescent flame retardant (IFR) incorporating organically modified montmorillonite (O-MMT) on the flame retardancy and melt stability of PLA were investigated. The flame-retardant PLA was prepared using a twin-screw extruder and a two roll mill. Then, the influence of IFR and MMT on flame retardancy and
melt stability was thoroughly investigated by means of l...

Preparation and properties of short natural fiber reinforced poly(lactic acid)(PLA) composites
The natural fiber/poly(lactic acid) (PLA) composites were prepared with ramie and jute short fiber as reinforcement and PLA as matrix. The mechanical and thermal properties of the composites were investigated. The results show that the properties of
the composites are better than those of plain PLA. When the content of the fiber is 30%, the composites can get the best mechanical properties....

Influence of Ammonium polyphosphate on the flame retardancy of ramie fiber reinforced poly(lactic acid) biocomposites
Fully degradable natural fiber/degradable polymer composites have received much research attention and have various applications such as in automotive components. But flammability limits their application; it is important to improve the flame retardancy of fully degradable composites with environmentally friendly flame retardants. Flame-retarded ramie fiberreinforced poly(lactic acid) (PLA) compos...

[Langmuir] Controlled evaporative self-assembly of polyacrylic acid in a confined geometry for fabricating pattern ed polymer brushes
A simple yet robust approach was exploited to fabricate large-scaled patterned polymer brushes by combining controlled evaporative self-assembly (CESA) in a confined geometry and self-initiated photografting and photo polymerization (SIPGP). Our method was carried out without any sophisticated instruments with lithograpy free, overcoming current difficulties in fabricating polymer patterns by us...

β-crystal formation of isotactic polypropylene under the combined effects of acid-corroded glass fiber and preshear
The acid-corroded glass fiber (GF)/isotactic polypropylene
(iPP) composite was injection molded by mixing–
injection molding (MIM). Through this method,
preshear can be imposed on melt during mix–plasticization
process. The crystalline structure across the
thickness direction of the injection-molded bars was
investigated by wide-angle X-ray diffraction and differential
scanning calo...

74. Boronic acid functionalized N-doped carbon quantum dots as fluorescent probe for selective and sensitive glucose determination
The nitrogen doped carbon quantum dots (NCQDs) with about 10 nm in diameter have been obtained by hydrothermal reaction from collagen. Because of the superiority of water dispersion, low toxicity and ease to functionlization, the NCQDs were designed as a glucose sensor after covalent grafting by APBA (APBA-NCQDs). The as-prepared APBA-NCQDs were imparted with glucose sensitivity and selec...
