Special Issue "Preparation and Application of Polymer Nanocomposites"
Deadline for manuscript submissions: 31 December 2021.
With the advent of nanotechnology, the incorporation of nanofillers to a polymer matrix has prompted a breakthrough in materials development, providing polymer nanocomposites with improved mechanical, thermal, electrical, dielectric, optoelectronic and magnetic properties. Typically, the nanofillers affect the properties of the host matrix, and contribute to the composite performance with properties of their own. The structure and behavior of the interface between the nanofiller and the matrix play a most relevant role. Effort is being devoted to study the mobility of nanofillers inside a matrix, their aggregation, or their possible release to the environment.
Polymer nanocomposites have found applications as membranes in batteries and fuel cells, in biomedicine, for drug delivery, or as scaffolds for tissue regeneration, and in electrical/optoelectronic devices such as solar cells. Smart, responsive materials have been developed and used as sensors, actuators, and low-voltage energy generators for wearables.
This Special Issue is focused on the characterization of polymer nanocomposite films with special emphasis on their structure and interface properties, and their mechanical and electrical response. Research addressing the impact on the nanofiller/matrix interface of external conditions such as heat, electrical/magnetic, mechanical, or ultrasonic action is of particular interest. Contributions related to biocompatible, ecofriendly, and biodegradable polymer nanocomposites are welcome.

Abstract: Guided bone regeneration (GBR) technique helps to restore bone tissue through cellular selectivity principle. Currently no osteoinductive membrane exists on the market. Osteogenic growth peptide (OGP) acts as a hematopoietic stimulator. This association could improve the quality of bone formation, benefiting more than 2.2 million patients annually. The objective of this work was to develop membranes from ureasil-polyether materials containing OGP. The membranes were characterized by differential scanning calorimetry (DSC) and small angle X-ray scattering (SAXS). OGP was synthesized by the solid phase method. Sterilization results using gamma radiation at 24 kGy did not change the structure of the material, as confirmed by DSC. The SAXS technique revealed the structural homogeneity of the matrix. OGP was incorporated in 66.25x10-10 mol and release results showed that the ureasil-PPO400/PEO500 and ureasil-PPO400/PEO1900 membranes released 7 and 21%, respectively, after 48 hours. In vivo results show that, after 60 days, 90% bone filling in the commercial group, 73% filling in the ureasil-PPO400/PEO500 (50/50) group, and 77% filling in the ureasil-PPO400/PEO1900 (80/20) group (no statistically significant), however, the differences with control group (24% bone filling). The results allow us to conclude that membranes with OGP have characteristics that make them potential candidates for the GBR.
