Nanocellulose from abundant sources is attracting attention because it offers excellent properties. There are a number of that can be used to extract cellulose such as algae, bacteria, non-wood and wood materials. Numerous methods were established in order isolate nanocellulose each method produced different types nanocellulose. However, there some limitations merging into polymeric material due the presence hydrophilic group structure. In overcome limitations, surface modification was...

This research work was prepared alpha pineapple leaf (PALF), which obtained the leaves of plant, Ananas comosus belonged to family Bromeliaceae. treated untreated samples were characterized using X-ray diffraction (XRD).

The term microfibril angle, MFA in wood science refers to the angle between direction of helicalwindings cellulose microfibrils secondary cell wall, S2 layer fibres and long axis wall.A method is presented for measurement, using small-angle X-ray scattering (SAXS), angle,(MFA) associated standard deviation walls ofAcacia mangium wood. length orientation irradiated volume ofthe thin samples are measured SAXS scanning electron microscope, (SEM). undeterminedparameters analysis MFA, (M) (σ?)...

Pineapple Leaf Fibers (PALF) which is rich in cellulose, relatively inexpensive and abundantly available has the potential for polymer reinforcement. In this study, Polyethylene Terephthalatate (PET) was added with PALF electro-spinned. The resulting mats were compared PET neat electrospun. samples later examined by Scanning Electron Microscope (SEM), Fourier Transform Infrared (FTIR) contact angle (CA).

Alkali treatment and bleaching have been applied on banana fibers obtained from harvested pseudo-stem of the plant Musa acuminata collected in Banting, Selangor, Malaysia. The structure morphology found to be affected by used alkaline bleaching. crystallite size percentage crystallinity untreated (raw fibers) treated (microfibrils cellulose) were investigated using X-Ray Diffraction (XRD). XRD studies shows that cellulose prepared such chemical (alkali treatment) more crystalline than fibers.

Cellulosic materials derived from pineapple leaves fibers (PALF) which are being wasted after fruit harvested. There two methods to extract cellulose PALF. First were using sodium hydroxide (NaOH) 2% for alkaline treatment and bleached by hypochlorite (NaClO) buffer. Second method, was extracted peroxyacetic acid delignification the sample in acidified pH 3 hydrogen peroxide solution. From X-Ray Diffraction (XRD) Fourier Transform Infrared Spectroscopy (FTIR) data’s, it is proven that both...
