Tetrel Bonds with π-Electrons Acting as Lewis Bases—Theoretical Results and Experimental Evidences
(MDPI, 2018-05-15)
MP2/aug-cc-pVTZ calculations were carried out for the ZFH(3)-B complexes (Z = C, Si, Ge, Sn and Pb; B = C2H2, C2H4, C6H6 and C5H5-; relativistic effects were taken into account for Ge, Sn and Pb elements). These calculations ...
Promotion of self-nucleation with latent Form I nuclei in polybutene-1 and its copolymer
(American Chemical Society, 2018-08-02)
The formation of Form I nuclei of polybutene-1 (PB-1) and its copolymer with polyethylene (PB1-ran-PE) has been studied by means of modified self-nucleation protocols. Even when the self-nucleation temperature was high ...
Influence of chain topology (cyclic versus linear) on the nucleation and isothermal crystallization of poly(L-lactide) and poly(D-lactide)
(American Chemical Society, 2018-02-20)
In this paper, ring closure click chemistry methods have been used to produce cyclic c-PLLA and c-PDLA of a number average molecular weight close to 10 kg/mol. The effects of stereochemistry of the polymer chains and their ...
Crystallization of isodimorphic aliphatic random copolyesters: pseudo-eutectic behavior and double-crystalline materials
(Elservier, 2018-02-28)
Isodimorphic random copolyesters are intriguing polymeric materials that can crystallize in their entire composition range, despite the random distribution of comonomer units along their chains. This behavior stems from ...
Uniaxial and Mixed Orientations of Poly(ethylene oxide) in Nanoporous Alumina Studied by X-ray Pole Figure Analysis
(American Chemical Society, 2018-11-16)
The orientation of polymers under confinement is a basic, yet not fully understood phenomenon. In this work, the texture of poly(ethylene oxide) (PEO) infiltrated in nanoporous anodic alumina oxide (AAO) templates was ...
Novel Biobased Polyamide 410/Polyamide 6/CNT Nanocomposites
(MDPI, 2018-09)
Biobased polyamide 410 (PA410)/multiwall carbon nanotube (CNT) nanocomposites (NCs) were obtained by melt-mixing in a twin screw extruder a Polyamide 6 (PA6)-based masterbatch (with 15 wt % CNT content) with neat PA410. ...
Graphene Based Poly(Vinyl Alcohol) Nanocomposites Prepared by In Situ Green Reduction of Graphene Oxide by Ascorbic Acid: Influence of Graphene Content and Glycerol Plasticizer on Properties
(MDPI, 2018-12-06)
The enhanced properties of polymer nanocomposites as compared with pure polymers are only achieved in the presence of well-dispersed nanofillers and strong interfacial adhesion. In this study, we report the preparation of ...
PCL/POSS Nanocomposites: Effect of POSS Derivative and Preparation Method on Morphology and Properties
(MDPI, 2018-12-26)
The incorporation of polyhedral oligomeric silsesquioxanes (POSS) molecules as nanoparticles into polymers can provide improved physico-chemical properties. The enhancement depends on the extent of dispersion of the ...
Biodegradable Polycarbonate Iongels for Electrophysiology Measurements
(MDPI, 2018-09)
In recent years, gels based on ionic liquids incorporated into polymer matrices, namely iongels, have emerged as long-term contact media for cutaneous electrophysiology. Iongels possess high ionic conductivity and negligible ...
Catechol End-Functionalized Polylactide by Organocatalyzed Ring-Opening Polymerization
(MDPI, 2018-02-06)
There is a great interest in incorporating catechol moieties into polymers in a controlled manner due to their interesting properties, such as the promotion of adhesion, redox activity or bioactivity. One possibility is ...
