42. [Materials Chemistry and Physics] The tough allograft adhesive behavior between polyacrylamide and poly(acrylic acid) hydrophobic association hydrogels
Polyacrylamide (PAAm) and polyacrylic acid (PAAc) hydrophobic association hydrogels were synthetized via free radical polymerization, respectively. Also, the hydrophobic alkyl groups were introduced into PAAm and PAAc to enhance the mechanical properties of hydrogels. It was found that PAAm and PAAc hydrophobic association hydrogels didn''''''''''''''''''''''''''''''''''''''''''''''''''''...

Stereo- and Temporally Controlled Coordination Polymerization Triggered by Alternating Addition of a Lewis Acid and Base
Significant progress has been made with regard to temporally controlled radical and ring-opening polymerizations, for example, by means of chemical reagents, light, and voltage, whereas quantitative switch coordination polymerization is still challenging. Herein, we report the temporally and stereocontrolled 3,4-polymerization of isoprene through allosterically regulating the active metal center...

Controlled crystallization of titanium dioxide particles in the presence of poly(vinyl alcohol) from peroxytitanic acid
Crystallization of TiO2 particles from peroxytatanic acid in the presence of poly(vinyl alcohol) (PVA) via a hydrothermal process was investigated. The crystal structure and morphology of TiO2 were significantly affected by pH and PVA dosage. High acidic condition without PVA led to the formation of rutile TiO2, while addition of PVA resulted in the formation of anatase TiO2. Much amount...

Comparison of the reinforcing effects for cellulose nanocrystals obtained by sulfuric and hydrochloric acid hydrolysis on the mechanical and th- ermal properties of bacterial polyester
Two kinds of cellulose nanocrystals (CNCs) obtained by sulfuric acid hydrolysis (CNC-S) and hydrochloric acid hydrolysis under hydrothermal condition (CNC-H) were used as organic nanoreinforcment to enhance the mechanical property and thermal stability of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV). Comparison of the reinforcing effects for different CNCs on the properties of PHBV was carr...

Fabrication of multifunctional cellulose nanocrystals/poly(lactic acid) nanocomposites with silver nanoparticles by spraying method
The poly (lactic acid) (PLA)/functionalized cellulose nanocrystals formates (CNFs) were prepared by solution casting and then the binary films were sprayed with silver ammonia aqueous solution to fabricate PLA/CNF/Ag ternary nanocomposites. It was found that both deposited silver (Ag) nanoparticles and CNFs showed efficient reinforcing effect on the thermal, mechanical, barrier properties and anti...

Polylactic acid nanocomposite films with spherical nanocelluloses as efficient nucleation agents: effects on crystallization, mechanical and thermal properties?
The low crystallization rate of commercial polylactic acid (PLA) restricts its application in food packaging materials. In this work, spherical nanocellulose formates (SCNFs) were incorporated into a PLA matrix to fabricate green nanocomposites. The addition of well-dispersed SCNFs significantly increased the crystallization rate, and thus led to obvious enhancements of the mechanical performance ...

Facile extraction of thermally stable cellulose nanocrystals with a high yield of 93% through hydrochloric acid hydrolysis under hydrothermal conditions
A facile approach for extracting cellulose nanocrystals (CNCs) was presented through hydrochloric acid hydrolysis of cellulose raw materials under hydrothermal conditions. The influences of preparation parameters, such as reaction time, reaction temperature, and acid-to-cellulose raw material ratio, and different neutralization methods on the yield, microstructure and properties w...

(ACS Sustain. Chem. Eng.) Hexahydro-s-triazine: A Trial for Acid-Degradable Epoxy Resins with High Performance
Hexahydro-s-triazine (HT) derivatives are acidsensitive compounds. 4,4′,4″-(1,3,5-Hexahydro-s-triazine-1,3,5-triyl) tris(N-(2-aminoethyl) benzamide) (HT-A) bearing three amino groups was synthesized as a curing agent to prepare the acid-degradable epoxy resin. The chemical structures of HT-A and its precursor were confirmed by 1H NMR and 13C NMR. The synthesized HT-A, as well as the commer...
