We study the effect of nonsolvent on the formation of polymer nanomaterials in the nanopores of porous templates. Water (nonsolvent) is added into a poly (methyl methacrylate) (PMMA) solution in dimethylformamide (DMF) confined in the nanopores of an anodic aluminum oxide (AAO) template. Water forms a wetting layer on the pore wall and causes the PMMA solution to be isolated in the center of th...

In this work, we examine binary and ternary nanocomposites of poly(methyl methacrylate) grafted silica nanoparticles (PMMA-NP), in poly(styrene-ran-acrylonitrile) (SAN), matrices as a platform to directly probe governing parameters guiding phase behavior nanoparticle assembly composite materials. Through the addition PMMA matrix chains similar molecular weight significantly smaller than SAN cha...

Thin layers of lamellar-forming polystyrene-block-poly (methyl-methacrylate) (PS-b-PMMA) provide the templates for fabricating nanowires with a “fingerprint” morphology. The electrical characteristics of the nanowires were measured, and largely deviated from simulated devices due to high defect density. Their highly curved conformation makes the nanowires strong candidates for electrical testin...

Single crystals of poly(ethylene glycol) (PEG)-b-polystyrene (PS), PEG-b-poly(methyl methacrylate) (PMMA), PEG-b-polycaprolactone (PCL), and polyaniline (PANI)-b-PEG-b-PANI were developed from dilute solutions and thin molten films using self-seeding methodology. The PS and PMMA grafted chains were categorized in disordered nano-brushes; however, the PCL and PANI ones were grouped in ordere...

Carbon nanotubes (CNT) are an attractive material for photonic applications due to their nonlinear optical properties, such as the nonlinear saturable absorption and high third order nonlinearity. However their utilization has been hindered by the lack of flexibility on the device design which rises from the current methods of Carbon nanotube deposition within the optical system. A suitable app...

The present work concerns the preparation of bone cements based on poly(methyl methacrylate) (PMMA), used mainly for prosthesis fixation and cavity filling for correction of human bone failures. A typical bone cement recipe contains methyl methacrylate, which polymerizes in situ during cement application. An inherent problem of this reaction is the large amount of heat released during the cemen...

This study aims at the testing of various low-k insulators deposited at temperatures below approximately 160 C for possible application in temperature-limited copper interconnects (e.g., in plastic electronics). Various polymers were tested such as the well-known poly(methyl methacrylate) (PMMA), a Polyhedral Oligomeric Silsesquioxane (POSS) based copolymer partially fluorinated (POSS-F) and th...

Introduction: Poly(methyl methacrylate), or PMMA bone cement has been a critical material in total joint replacement for over four decades. Modifications used to improve the standard polymer powder/methacrylate monomer system have included the addition of fiber reinforcing phases, bioactive ceramics, antibiotic agents, etc. The microstructural phases in PMMA bone cement can affect its fracture ...

Strength and toughness have been often considered as mutually exclusive properties in many synthetic materials. Natural materials like nacre overcome this conflict by optimizing internal architecture at the nanoscale. In work, nacre-inspired graphene oxide (GO)-poly (methyl methacrylate) (PMMA) nanocomposite is fabricated, which has a “brick mortar” microstructure enhanced interfacial strength....

In this paper, the influence of solvents and reinforcement processing methods on mechanical properties nanocomposite poly-(methyl methacrylate) PMMA-Ti3C2Tx MXene was investigated. A weight fraction 1% two types were used for sample preparation: dimethylformamide (DMF) acetone (Ac). Deionized water DMF to delaminate MXene. An additional peak at 1675 cm-1 observed FTIR spectra obtained samples, ...
