Smart polyaniline nanoparticles with thermal and photothermal sensitivity
(IOP Publishing, 2014-11)
Conductive polyaniline nanoparticles (PANI NPs) are synthesized by oxidation of aniline with persulfate in acid media, in the presence of polymeric stabilizers: polyvinilpyrrolidone (PVP), poly(N-isopropylacrylamide) ...
Polyaniline-modified cellulose nanofibrils as reinforcement of a smart polyurethane
(Soc Chemical Industry, 2011-05-24)
Segmented polyurethanes exhibiting shape memory properties were modified by the addition of polyaniline (PANI)-coated cellulose nanofibrils (CNFs). The two-phase structure of the polymer is responsible for the material's ...
A pH-responsive foam formulated with PAA/gemini hernán martinelli 12-2-12 complexes
(MDPI AG, 2021-07-19)
In the search for responsive complexes with potential applications in the formulation of smart dispersed systems such as foams, we hypothesized that a pH-responsive system could be formulated with polyacrylic acid (PAA) ...
Toward pH-controllable bioelectrocatalysis for hydrogen peroxide based on polymer brushes
(2013-04-01)
In the present work, a biosensor was built with smart material based on polymer brushes. The biosensor demonstrated a pH-sensitive on-off property, and it was further used to control or modulate the electrochemical responses ...
Smart Polymer Surfaces with Complex Wrinkled Patterns : Reversible, Non-Planar, Gradient, and Hierarchical Structures
(2023-02)
This review summarizes the relevant developments in preparing wrinkled structures with variable characteristics. These include the formation of smart interfaces with reversible wrinkle formation, the construction of wrinkles ...
Novel poly(NIPA-co-AAc) functional hydrogels with potential application in drug controlled release
(American Chemical Society, 2014-05)
The synthesis, characterization and properties of pH/thermosensitive hydrogels based on acrylic acid (AAc) and N-isopropylacrylamide (NIPA) using (+)-N,N′-diallyltartramide (DAT) as cross-linking agent and water as solvent, ...
Nanofibrous membranes as smart wound dressings that release antibiotics when an injury is infected
(Elsevier Science, 2019-12-03)
Simple and coaxial electrospinning were used for the preparation of nanofibers containing antibiotic. The use of a pH-sensitive polymer provided the membranes with a selective releasing capability, as a function of the ...
Thermal and pH dual responsive polyurethane/2-(diisopropylamino)ethyl methacrylate hybrids: Synthesis, characterization, and swelling behavior
(Taylor & Francis Ltd, 2017-12)
This article describes the synthesis and characterization of stimuli-sensitive hybrid films using 2-(diisopropylamino)ethyl methacrylate (DPA), and a polyurethane (PU) base on isophorone diisocyanate. Hybrid films with ...
Reversible swelling as a strategy in the development of smart membranes from electrospun polyvinyl alcohol nanofiber mats
(John Wiley & Sons Inc, 2020-02)
This work presents an electrospun nanofibrous membrane for water treatment, designed to reduce its pores through polymer swelling to retain contaminants, and after that, reopening them for easy cleaning. It consists of a ...
