Effect of crystallinity on CF/PPS performance under weather exposure: Moisture, salt fog and UV radiation
(2018-07-01)
The crystalline content of a composite can affect its performance under environmental conditions. The objective of this study is to evaluate the influence of the crystallinity degree of CF/PPS composites to hygrothermal, ...
Liquid Crystalline Nanostructured Polymer Blends
(2015-09-23)
Polymeric materials presenting liquid crystalline domains are attracting increasing attention from academia and industry due to their unique properties, particularly for optical applications and as components of high-strength ...
Design and characterization of a novel p1025 peptide-loaded liquid crystalline system for the treatment of dental caries
(2016-02-01)
Dental caries, mainly caused by the adhesion of Streptococcus mutans to pellicle-coated tooth surfaces, is an important public health problem worldwide. A synthetic peptide (p1025) corresponding to residues 1025-1044 of ...
Films from resistant starch-pectin dispersions intended for colonic drug delivery
(2014-01-01)
Free films were obtained by the solvent casting method from retrograded starch-pectin dispersions at different polymer proportions and concentrations with and without plasticizer. Film forming dispersions were characterized ...

Side chain liquid crystalline composites, occurrence of interdigitated bilayer smectic c phases
(2011)
We report on the results of X-ray investigations in two series of polymer monomer composites, PM6Rm-33 and PMnR12-33, which consist of mixtures of achiral liquid crystalline side chain polymers and their monomers. These ...
X-ray study of bilayered tilted structures in liquid crystalline side chain methacrylic polymers
(TAYLOR & FRANCIS LTD, 2003-05)
The synthesis and measurement of thermodynamic properties of six methacrylate-based polymers were undertaken to observe the relationship between structural aliphatic features and mesophase properties. X-ray measurements ...
Polyethyleneimine and Chitosan Polymer-Based Mucoadhesive Liquid Crystalline Systems Intended for Buccal Drug Delivery
(2018-02-01)
The buccal mucosa is accessible, shows rapid repair, has an excellent blood supply, and shows the absence of the first-pass effect, which makes it a very attractive drug delivery route. However, this route has limitations, ...
Determination of the Real Influence of the Addition of Four Thickening Agents in Creams Using Rheological Measurements
(2013-04-01)
This study aimed to characterize different emulsions obtained by the addition of four thickening agents, using rheological measurements, beyond analyzing the emulsions by polarized light microscopy looking for liquid ...
