Aloe Vera Jel (AVG)/PVA/PLLA Katmanlı Nanobiyokompozitlerin Mekanik Özelliklerinin Araştırılması

Abstract

Aloe vera (AVG) jel formundadır ve yara iyileşmesinde kullanılır. PVA suda çözünebilen, biyolojik olarak parçalanabilen bir polimerdir. PLLA termoplastik bir polimerdir, mukavemeti ve elastikiyeti arttırır. Bu çalışmada ilk olarak PLLA polimeri elektro eğirme işlemiyle nanolifli yüzey formuna dönüştürüldü. İkinci aşamada, elektro eğirme yöntemi ile PLLA nanolifleri üzerine Aloe vera (AVG)/PVA karışımı uygulanarak 2 katmanlı biyonanokompozitler üretildi. Bu katmanlı nanobiyokompozit yapılar ve %0, %5, %10 ve %20 oranlarında AVG içeren nanolifler, viskozite, iletkenlik, pH, SEM, çekme mukavemeti, esneme %, incelik, FT-IR, XRD enstrümantal yöntemleri kullanılarak araştırıldı. AVG ilavesinin nanobiyokompozit yapıya etkileri incelendi.

Investigation of Mechanical Properties of Aloe Vera Gel (AVG)/PVA/PLLA Layered Nanobiocomposites

Abstract

Aloe Vera Gel (AVG) is a product obtained from the leaf portion of the Barbadensis Miller plant and known for its wound-healing properties. PVA is a water-soluble, biologically disintegrated polymer. PLLA, the stereoisomer of the biodegradable polylactic acid obtained from corn, is a thermoplastic polymer and has properties such as strength and elasticity. In this study, in the first stage, PLLA polymer was converted into nanoweb form as a carrier layer. In the second stage, two-layer nanobiocomposites were produced by applying aloe vera (AVG)/PVA mixture on the existing PLLA nanoweb on the collector of the electrospinning device. The effects of the AVG addition of AVG/PVA/PLLA nanobiocomposite structures containing 0 %, 5 %, 10 %, and 20 % of AVG were examined by using instrumental methods such as viscosity, conductivity, pH, SEM, tensile strength, stretch %, delicacy, FT-IR, and XRD.As a result, the percentage of crystallization due to the AVG ratio in the mixtures increased and has been found to provide resistance to the structure. This feature will be the source for the formation of biocrheable resistant materials in future medical studies related to AVG.
