A Borinic Acid Polymer with Fluoride Ion- and Thermo-responsive Properties that are Tunable over a Wide Temperature Range
A new type of smart borinic acid polymer with luminescence and multiple stimuli-responsive properties is reported. In DMSO with small amounts of water, the homopolymer PBA shows a tunable upper critical solution temperature (UCST). As the amount of water increases from 0 to 2.5% (v/v), the UCST rises linearly from 20 degrees C to 100 degrees C (boiling point of water). Thus, the thermal responsive...

Borinic acid block copolymers: new building blocks for supramolecular assembly and sensory applications
Borinic acid block copolymers have been prepared by reversible addition-fragmentation chain transfer (RAFT) polymerization and investigated as “smart materials” in sensory applications. Taking advantage of the hydrogen bond donating ability of the borinic acid groups, supramolecular aggregates of PNIPAM-b-PBA were generated by complexation with P4VP. The P4VP complex showed greatly improved fluo...

In situ generation of bioreducible and acid labile nanogels/microgels simply via adding water into the polymerization system.
A novel and versatile method for one-pot and in situ generation of bioreducible and acid labile nanogels/microgels simply via adding water into the polymerization system is reported. The produced polymers in the polymerization system become temperature-sensitive and less soluble after adding water, and hence they collapse together, forming nanoparticles. Subsequently, the disulfid...

Enhanced in vitro mineralization and in vivo osteogenesis of composite scaffolds through controlled surface grafting of L-lactic acid oligomer on nano-hydroxyapatite.
Abstract
Nanocomposite of hydroxyapatite (HA) surface grafted with L-lactic acid oligomer (LAc oligomer) (op-HA) showed improved interface compatibility, mechanical property, and biocompatibility in our previous study. In this paper, composite scaffolds of op-HA with controlled grafting different amounts of LAc oligomer (1.1, 5.2, and 9.1 wt %) were fabricated and implan...

Hyaluronic acid stabled iodine-containing nanoparticles with Au nanoshell coating for X-ray CT imaging and photothermal therapy of tumors
In recent years, considerable efforts have been made for the development of multifunctional nanoparticles with diagnosis and therapy functions. To achieve enhanced CT imaging and photothermal therapy on the tumor, we employed iodinated nanoparticles as template to construct Au nanoshell structure and demonstrated a facile but effective approach to synthesize biocompatible and well-dispersed multif...

A facile approach to modify polypropylene flakes combining O2-plasma treatment and graft polymerization of l-lactic acid
Modification of polypropylene (PP) surface with poly(l-lactic acid) (PLLA) via a facile approach was described. The PP flakes were first treated with O2 plasma and then grafted with l-lactic acid (LLA) monomer in the aqueous solution. The attenuated total reflectance Fourier transform infrared (ATRFTIR) spectroscopy, atomic force microscopy (AFM) and X-ray photoelectron spectroscopy...

Grafting of telechelic poly(lactic-co-glycolic acid) onto O2 Plasma Treated Polypropylene Flakes
In this work, we described a facile approach to preparing polypropylene (PP) surface functionalized with telechelic poly(lactic-co-glycolic acid) (HOPLGA-COOH). The PP flakes were first treated with oxygen plasma and then grafted with different molecular
weight PLGA (Mw ? 50, 100, and 300 K) in dry dichloromethane solution with the addition of phosphorus pentachloride (PCl...

Preparation of poly (L-lactic acid) modified polypropylene mesh and its anti-adhesion in experimental abdominal wall defect repair
A new type of polypropylene (PP) hernia mesh,
modified with poly(L-lactic acid) (PLLA), was developed and
used to repair rat abdominal wall defect. The PP mesh was
first treated with oxygen plasma and then grafted with PLLA
in phosphorus pentachloride (PCl5) solution in dichloride
methane. The water contact angle changed during the procedure,
and the coverage percentage of PLLA on the PP was
about...
