Резюме: Масштабирование биосинтеза БНЦ позволило получить образцы композиционной бумаги с повышенной долей БНЦ. Целью работы являлось исследование образцов композиционной бумаги из БНЦ и сульфатной беленой хвойной целлюлозы (ХвЦ) с соотношением компонентов в широком диапазоне – 10:90, 30:70, 50:50, 60:40, 70:30, 90:10. Выбор метода изготовления бумаги осуществлен на основе результатов определения прочностных и деформационных показателей образцов композиционной бумаги с соотношением БНЦ:ХвЦ 20:80. Метод с поверхностным нанесением БНЦ на отливки ХвЦ позволил повысить показатели прочности (сопротивление раздиранию – на 37%, сопротивление продавливанию – на 17%) и деформационные показатели (жесткость при растяжении – на 66%, работу разрушения – на 8%, разрывную длину – на 4%) по сравнению с контролем. Во всех образцах подтверждено образование композиций. Методом растровой электронной спектроскопии установлено, что композиции бумаги состоят из переплетенных микроразмерных волокон ЦвХ и наноразмерных волокон БНЦ, причем по мере повышения в композициях доли БНЦ наблюдалось «уплотнение» структуры за счет увеличения доли сетчатых наноразмерных фрагментов. Данные ИК-спектроскопии свидетельствуют о сходстве целлюлозной структуры всех образцов. Установлено, что возрастание значений степени полимеризации образцов композиционной бумаги прямо пропорционально увеличению доли БНЦ в образцах. Изучена фильтрующая способность образцов композиционной бумаги по отношению к микроорганизмам культуральной жидкости продуцента Medusomyces gisevii Sa-12. Отмечено, что удерживание дрожжей достигается при содержании в композиционной бумаге 70% БНЦ. Представленные свойства нового материала обуславливают перспективы его использования для фильтрования микроорганизмов.

Abstract: Scaling biosynthesis of bacterial nanocellulose (BNC) allowed samples of composite paper with an increased proportion of BNC to be obtained. This work aims to study BNC samples and bleached soft wood kraft pulp (BSKP) composite paper with a ratio of components varying across a wide range: 10:90, 30:70, 50:50, 60:40, 70:30, 90:10. The method of paper manufacturing was chosen based on the determinations of strength and deformation properties of composite samples with the BNC:BSKP ratio of 20:80. Surface application of BNT on BSKP handsheet provided for an increase in the strength values (tear resistance – by 37%, burst index – by 17%) and deformation characteristics (tension stiffness – by 66%, fracture work – by 8%, breaking length – by 4%) compared to a reference sample. The formation of composites is confirmed in all samples. Scanning electron spectroscopy revealed that paper composites comprise interlaced micro BSKP and nano BNC fibres. As the proportion of BNC in composites elevated, densification of the structure was observed due to an increased fraction of cross-linked nanosized elements. IR spectroscopy indicated the resemblance of cellulose structure in all samples. It was found that an increase in the degree of polymerisation of composite paper is directly proportional to an increase in the BNC amount in the samples. The filtering ability of composite paper samples against microorganisms in the culture liquid of the Medusomyces gisevii Sa-12 producer was studied. It should be noted that yeast retention is achieved with 70% BNC in the paper composite. The presented properties of the new material determine prospects for its use in filtering microorganisms.
