Abstract:

 Basaltic pumice has a black or gray appearance due to its iron and magnesium-rich komatiitic tuff composition. Pumices porous structure allows the production of various polymer-based bio-composite materials for biomedical applications. This study developed bio-composite samples by incorporating basaltic pumice powder at 2.5, 5.0, 7.5, and 10.0 percent concentrations into an elastomeric polyurethane EPU matrix. The surface and elemental structure of basaltic pumice particles were investigated using the SEMenergy diffraction X-ray technique. The physical, mechanical, thermal, melt-flow, and morphological properties of bio-composites were studied experimentally. Findings showed a rise in Shore hardness and tensile modulus parameters and declined tensile elongation. According to the thermal study, introducing basaltic pumice resulted in a modest drop in the thermal stability of the EPU and an improvement in stability against mechanical deformations. Pumice loadings raised the melt flow and extrusion torque values of the EPU. The observation of the homogeneously distributed pumice particles in the EPU matrix is used as visual evidence to investigate the highest performance among the composites in the EPU sample with the lowest loading rate of 7.5 pumice. Overall, BP is effective as a reinforcing agent in EPU-based bio-composites at low additive percentages.

 Bazaltik pomza, demir ve magnezyum açısından zengin komatitik tüf bileşimi nedeniyle siyah veya gri bir görünüme sahiptir. Pomzanın gözenekli yapısı, biyomedikal uygulamalar için çeşitli polimer esaslı biyo-kompozit malzemelerin üretimine olanak tanır. Çalışmada, biyo-kompozit numuneler biyo-esaslı elastomerik poliüretan EPU matrisine 2.5, 5.0, 7.5 ve 10.0 konsantrasyonlarında bazaltik pomza tozu eklenerek geliştirilmiştir. Bazaltik pomza parçacıklarının yüzey ve element yapısı, SEMenerji kırınımı X-ışını tekniği kullanılarak incelenmiştir. Biyo-kompozitlerin fiziksel, mekanik, ısısal, eriyik-akış ve morfolojik özellikleri deneysel olarak incelenmiştir. Ponza içeren kompozitler, doldurulmamış EPU ile karşılaştırıldığında, bulgular Shore sertliği ve çekme modülü parametrelerinde artış, çekme uzamada azalma olduğunu göstermiştir. Numunelerin termal çalışmasının sonuçlarına göre, bazaltik pomza eklenmesi EPUnun ısısal kararlılığında az bir düşüşe ve mekanik deformasyona karşı kararlılıkta bir iyileşmeye neden olmuştur. Ponza yüklemeleri, EPUnun eriyik akış ve ekstrüzyon torku değerlerini artırmıştır. Bu numunenin taramalı elektron mikroskobu fotoğraflarında EPU matrisinde homojen olarak dağılmış pomza parçacıklarının gözlemlenmesi, 7.5 pomza olan en düşük yükleme oranına sahip EPU numunesindeki kompozitler arasında en yüksek performansı araştırmak için görsel kanıt olarak sunulmuştur. Genel olarak, bazaltik pomza düşük katkı yüzdelerinde EPU biyo-kompozitlerde bir takviye maddesi olarak etkilidir.
