Enhancing performance of in-situ synthesized biocompatible shape memory polyurethane acrylate by cellulose nanocrystals.

This study presents the development of biocompatible and biodegradable nanocomposites utilizing renewable cellulose nanocrystals (CNCs) in polycaprolactone (PCL)-based polyurethane acrylates (PUA) through in situ polymerization. First, CNCs were derived from cotton linter via acid hydrolysis; then functionalized with 3-methacryloxypropyltrimethoxysilane to produce silane-modified CNCs (S-CNCs). CNCs offered uniform dispersion in PUA up to 2 wt% loading, resulting in significant property enhancements, including ~60 % increase in tensile strength and ~25 % increase in Young's modulus.

Highly biocompatible multifunctional hybrid nanoparticles based on FeO decorated nanodiamond with superior superparamagnetic behaviors and photoluminescent properties.

The multifunctional nanostructures with superparamagnetic and luminescent properties undergo revolution in the field of bio-nanotechnology. In this article, we reported a facile and efficient one-step modified co-precipitation method to load superparamagnetic FeO nanoparticle on oxidized nanodiamond (Ox-ND). Subsequently, the as-prepared Ox-ND/FeO hybrid nanoparticle was surface functionalized with vinyltrimethoxysilane (VTMS) to enhance its compatibility with organic media.

Polymer/nanodiamond composites - a comprehensive review from synthesis and fabrication to properties and applications.

Nanodiamond (ND) is an allotrope of carbon nanomaterials which exhibits many outstanding physical, mechanical, thermal, optical and biocompatibility characteristics. Meanwhile, ND particles possess unique spherical shape containing diamond-like structure at the core with graphitic carbon outer shell which intuitively contains many oxygen-containing functional groups at the outer surface. Such superior properties and unique structural morphology of NDs are essentially attractive to develop polymer composites with multifunctional properties.
