Abstract Light‐driven soft actuators with adaptive shape changes, diverse geometric morphing, and reversible macroscopic movements have gained ever‐increasing interest owing to their applications ranging from biomedical aerospace devices. Herein, presented is a near‐infrared (NIR) light‐stimulated actuator based on cis ‐1,4 polybutadiene‐polyethylene semicrystalline copolymer. In the system, newly synthesized croconaine dye,...
A polymer network based on a <italic>cis</italic>-1,4-polybutadiene–polyethylene copolymer exhibits multi- and two-way shape memory effects as well high-strain capacity.
Highly <italic>trans</italic>-1,4-stereoregular polybutadiene (TPB) was obtained by CCTP and novel amphiphilic copolymers (TPB-<italic>b</italic>-PCL/PLA) were successfully synthesized.
Stereoblock polybutadiene (PBD) composed of amorphous equibinary cis−1,4/1,2 PBD (e-PBD, soft) and crystalline syndiotactic 1,2-PBD (s-1,2-PBD, hard) segments is synthesized through one-pot sequential polymerization with iron(III)2-ethylhexanoate/triisobutylaluminum/diethyl phosphate [Fe(2-EHA)3/Al(i-Bu)3/DEP] catalyst system. The first-stage 1,3-butadiene (BD) carried out at a low [Al]/[Fe] ratio to give e-PBD block, sequentially, the in situ addition excessive Al(i-Bu)3 BD living system...
Two triblock copolymers, polybutadiene‐ block ‐poly(ε‐caprolactone)‐ ‐poly(methyl methacrylate) (PBD‐ b ‐PCL‐ ‐PMMA) and ‐polystyrene ‐PS), are synthesized by combination of coordinative chain transfer polymerization (CCTP), ring‐opening (ROP), atom radical (ATRP). The molecular structures these polymers determined 1 H NMR gel‐permeation chromatography (GPC) analysis. resulting copolymers evaluated as compatibilizing agents for highly immiscible binary PBD/PMMA PBD/PS blends. presence...
Abstract Background Globally, millions of patients suffer from regenerative deficiencies, such as refractory wound healing, which is characterized by excessive inflammation and abnormal angiogenesis. Growth factors stem cells are currently employed to accelerate tissue repair regeneration; however, they complex costly. Thus, the exploration new regeneration accelerators considerable medical interest. This study developed a plain nanoparticle that accelerates with involvement angiogenesis...
Some ionic liquid-supported Schiff bases 3 have been synthesized by condensation of aromatic aldehydes 2 with the liquid 1-(2-aminoethyl)-3-methylimidazolium hexafluorophosphate 1 without solvent.The structure 3a has proven single crystal X-ray crystallography.
A simple, efficient, inexpensive one-pot method for the benzo [d][1,3]selenazole derivatives synthesized from 2-bromoaniline was developed by using cheap carbon-supported copper as catalyst at room temperature.The reaction provides an efficient protocol to a series of in good high yields, and benefits readily available synthesis efficiency.Keywords synthesis; [d][1,3]selenazole; 含硒化合物因为其广泛的生物活性, 引起了科学家 们的强烈兴趣 [1] .Bayoumy 等 [2] 证实, 某些合成的有机硒 化物比天然硒化物有着更强的生物活性, 而毒性则更 低. 例如, 硒原子直接与芳环相连的有机硒化合物,...
The synthesis of polymers with tailor-made microstructures and desired properties by controlling the regio- stereoselectivity olefin polymerization is an important research area in polymer science. In recent years, achievements were made to stereoblock copolymer having different tacticity each segment such as crystalline-amorphous blocks from a single monomer. A consisting stereospecific sequences one chain, shows special physical original stereoregular which could be applied thermoplastic...
The title mol-ecule, C(16)H(18)Se(2), features a diselenide bridge between two 4-methyl-benzyl units, in which the central C-Se-Se-C torsion angle is 88.1 (3)°, while Se-Se-C-C fragments assume gauche conformations, with angles of -51.8 (5) and 59.1 (4)°. dihedral benzene rings 78.9 (2)°.
Abstract Shape memory polymers (SMPs) are developed by blending and cross-linking which include crystalline domains cross-linked networks. In this paper, we describe the morphology, thermal shape behavior of methyl vinyl silicone rubber (MVMQ)/olefin block copolymer (OBC) blends prepared a melt-blending chemical method. MVMQ without could not hold its temporary shape. After introducing OBC, obtained exhibited excellent dual properties. The networks acted as reversible domains, while regions...
